ABSTRACT
The current aim of the Ethiopia‟s Millennium Development Goal declaration is to
alleviate poverty through improving the strategy of effective utilization of water
supply sources. In order to achieve the goal, a priority area is providing adequate and
quality water. The study was conducted in Simada District, Amhara Regional State,
Ethiopia, where after considerable expansion of the water supply systems, people still
rely on unimproved water sources that may be contaminated with waterborne diseases.
The objective of the research was to investigate the reasons behind the use of
unprotected sources in both urban and rural settings. Sixteen water points were
selected. Three water points (that were functional) were located in urban areas, and the
remaining 13 in rural areas ranged from nonoperational to completely functional.
Forty four households were interviewed in the urban area and 116 in the rural area,
covering water consumption behavior, perception of water source quality, and factors
determining use. Water quality was determined at 11 selected water points
representing both improved and unimproved sources.
In the urban areas people were generally satisfied with the water services provided by
the municipality because the water quality was good and walking distances were short.
The water cost was considered high especially for the poor who could not afford the
cost and therefore used alternative unprotected services. In response, the municipality
recently lowered the cost. . In other cases, because most of the systems were only a
few years old, some people were not adjusted to taste and went back to the original,
lower quality water sources. On some days, waiting times were too long, forcing some
people to use a more distant, unimproved source.
In contrast, more people in the rural areas did not use the constructed water points
because of the quality of water, adequacy, distance and longer waiting times. Systems
had broken down or failed for several reasons, the main one being that a functional
organization did not exist within the community to manage the water supply. Other
people who were dissatisfied did not like the taste of the water, could not pay for the
water services and therefore sought out alternative unimproved sources.
Sanitation coverage in urban areas was much less than that in rural areas where more
extension and promotion has been conducted. Construction of latrines without waste
decomposition or removal mechanisms service and the habit of open defecation were
common problems especially in urban peripheries.

CHAPTER ONE
1. INTRODUCTION
1.1 Background
Ethiopia is one of the member countries that adopted the millennium development
declaration with its main objective of poverty reduction (UNDP, 2008). This resulted
in prioritizing accessibility to improved water supply. Prior research has revealed that
access to clean water, sanitation and hygiene are the significant elements for poverty
alleviation (Water Aid, 2009).
Access to safe drinking water and sanitation is a global concern. However, developing
countries, like Ethiopia, have suffered from a lack of access to safe drinking water
from improved sources and to adequate sanitation services (WHO, 2006). As a result,
people are still dependent on unprotected water sources such as rivers, streams,
springs and hand dug wells. Since these sources are open, they are highly susceptible
to flood and birds, animals and human contamination. In addition, most sources are
found near gullies where open field defecation is common and flood-washed wastes
affect the quality of water.
According to an ADF (2005) report, the Millennium Development Goals (MDG)
objective of Ethiopia is to increase the improved water sources coverage from 2004
levels of 25% water supply and 8% sanitation to 62% for water supply and 54%
sanitation by 2015. As a consequence, governmental and nongovernmental
organizations made efforts to construct improved sources to provide access to safe and
potable drinking water. Despite these efforts, improved water sources are often located
far from user households, and due to the undulating nature of the country‟s
2
topography, water sources often occur at inconvenient locations, forcing people to
travel long distances over continuous short and long steep slopes. This resulted in
more waiting times, inadequate supply, lack of income and lack of quality being the
characteristics of many improved schemes (Admasu et al., 2002).
These factors lead to less access to water needed by the household for consumption
and forced households to seek out alternate unimproved and unhealthy nearby water
sources due to reluctance in using improved sources. It is common that people who are
most vulnerable to water-borne diseases are those who use polluted drinking water
sources. The report from UNICEF (2010), in the world 884 million people use
unimproved drinking water sources in 2010, and in 2015 estimates about 672 million
people will still using unimproved drinking water sources. The WHO (2000) revealed
that seventy five percent of all diseases in developing countries arise from polluted
drinking water. The lack of access to water also limits sanitation and hygiene practices
in many households because of the priority given for drinking and cooking purposes.
Water quality concerns are often the most important component for measuring access
to improved water sources. Acceptable quality shows the safety of drinking water in
terms of its physical, chemical and bacteriological parameters (WHO, 2004). User
communities‟ perceptions of quality also carry great weight in their drinking water
safety (Doria, 2010). Depending on their perception on taste, odor and appearance
(Sheat, 1992; Doria, 2010), this can lead to having different opinions about the
aesthetic values of water quality. Consumer perceptions and aesthetic criteria need to
be considered when assessing drinking water supplies even though they may not
adversely affect human health (WHO, 2004).
3
Despite the best governmental and nongovernmental efforts, a large percentage of the
water supply schemes are malfunctioning, forcing consumers to use unprotected
sources that pose health hazards and which thus seriously affect their productivity. It is
imperative to ensure that the water supply and sanitation services are adequate,
affordable and reliable.
The study was conducted in Amhara region Simada district where many governmental
and nongovernmental efforts focused on water supply projects. Despite the
opportunity for urban inhabitants to use tap water stands installed in the past few
years, people are still collecting water from previously used distant water sources
because of dissatisfaction with the change in the taste of the water, low income and
longer waiting time as compared with the old protected springs. As a result of this
dissatisfaction, consumers generally expect their water to have little or no flavor.
People can detect variations in pH, mineral and organic content of drinking water
(Dietrich, 2006). The variation in pH is detected indirectly, with greater acidity
increasing corrosivity that in turn can contaminate the water, and which implies a
change in the taste of water. In contrast, even though many water points have been
built by different implementing projects in many areas, drinking water scarcity is still
a great problem. Distance from the source to the house, waiting time, adequacy,
quality and early failure of the scheme are common phenomena which force
households to seek alternative unimproved water sources.
Sanitation service in the urban1 area is limited as compared to the rural areas which are
supported by different projects. The habit of open defecation nearby the water source,
the installation of oil machines in close proximity to the water source and increase
1 Urban area is defined as an area with more than 10,000 inhabitants, where the distance between
houses normally do not exceed 100 meters
4
number of dwellers in the vicinity of the water source are visible problems in urban
sites, rendering water sources susceptible to water contamination.
1.2 Justification
Creating community awareness of their water supply and sanitation services is one of
the options for improving sustainable access (Mtinda, 2007). Improving the water
supply coverage and quality has a number of consequences in addition to the fact that
investigating the socioeconomic and other factors affecting household water
consumption patterns provides guidance for policy makers and those in various
agencies implementing projects. It also ensures the projects capture the major points to
be considered before installation begins and ensures the ongoing provision of a service
that is fundamental to improve health, reducing the burden of women and children
carrying water long distances, and enabling users to live a life of dignity. Water supply
and sanitation services should not be seen as isolated factors (Water Aid, 2009).
Furthermore to achieve the MDGs of access to improved water sources is better to
incorporate each element to understand and recommend the major factors which
hinder the vision of the long term programs for the provision of safe or quality water
and sanitation services is very crucial.
1.3 Problem
Lack of access to safe and clean water is locked in the heart of the poverty. Even
though the issue of water is observed as a general problem for both the urban and the
rural population, women bear the greatest burden because of their social gender roles
including collecting water for their households (Rose, 2009). Because of their task of
water provision at the households, women and children suffer from disease, have
5
limited participation in education, and both income generating activities and
engagement in cultural and political issues are often compromised.
Several studies have been carried out to analyze people's perception and attitude about
the drinking water source quality and accessibility. Creating good community
awareness about water quality issues and the associated problems like sanitation and
hygiene services is important to alleviate health effects but it remains below the
expected rate of coverage.
By the year 2015 the national water supply and sanitation program under its
millennium development goal planned to increase the coverage of water supply and
sanitation by 64% and 54% respectively. It has been said that the chances of achieving
the Millennium Development Goal of halving the proportion of people without access
to safe water by 2015 will be seriously lowered unless levels of sustainability can be
greatly improved (Haysom, 2006; Harvey et.al, 2007).
1.4 Goals and Objectives
The main goal of the research is to improve access to water supply systems of both
rural and urban area by assessing current services that provide clean and safe water to
households. The general objective is assessing the reason behind the decision of
people to use unimproved water sources rather than available constructed water points
both in urban and rural areas.
6
The specific objectives are:
To assess the presence of alternative water sources used.
To assess the time required and distance individuals must travel to access
water sources for urban and rural households.
To assess the demand pattern both from unimproved and improved sources at
the household and per capita level.
To assess attitudes in urban and rural areas on the relationship between water
quality, the degree of water source protection and sanitation behaviors.
To determine how community perception on water quality is related to the
actual measured water quality.
To determine the key factors contributing to the continued use of unimproved
water sources and the reluctance to use existing improved water sources.

CHAPTER TWO
2 LITERATURE REVIEW
2.1 The Need for Water Supply and Sanitation
Access to water is a prerequisite for health and livelihood, which is why the MDG
target is formulated in terms of sustainable access to affordable drinking water supply.
The availability of improved and quality water supply and sanitation infrastructures
are widely recognized as an essential component of human rights, social and economic
development (ADF, 2005).
The poor and marginalized people living in rural and peri-urban settlements are most
in need for improved and safe drinking water, appropriate forms of sanitation and
access to water for other domestic purposes (Crow, 2001). The WHO (2000) reports
that polluted drinking water causes about1.8 million people die from diarrheal diseases
annually worldwide. Ethiopia is a country in which the water supply and sanitation
infrastructure endeavors are still low. Table 1 below shows the percent coverage of
improved and unimproved water supply sources in Ethiopia:

Source: WHO (2006), access to improved and unimproved sources
Even though improved2 water sources are available, they are often far away from the
beneficiary households and are located at inconvenient locations. The management
system of stakeholders coupled with water quality problems and inaccessible water
sources are some of the basic problems (Demeke, 2009; Bhandari and Grant, 2007).
The topography of Ethiopia is characterized by rugged landscapes on which women
and children travel long distances by carrying large containers up and down steep
slopes. Full water cans may weigh up to 65 kilograms (Demeke, 2009). In addition to
that, the lack of safe water supply has other series negative consequences such as the
workload in fetching unsafe water from mostly distant unimproved3 or traditional
water points make them vulnerable to health problems. As a result, most of the
children miss the opportunity of attending school, while women spend 10-50% of their
daytime fetching water from polluted water points, losing time on productive activities
(Ethiopian Water Resources Management Policy, 1999; Crow, 2001). According to
2 An improved drinking water source is defined as a type of drinking water facility or water delivery
point that by the nature of its design protects the drinking water source from external contamination,
particularly or faecal origin and which can be piped into dwelling, plot or yard, public tape/stand pipe, tube well/borehole, protected dug well, rain water collection and protected springs (Van Norden 2007
as cited by Sutton, 2008). 3 Unimproved sources include unprotected dug well, unprotected springs, tanker truck, surface water
(river, dam, lake, pond, stream, and irrigation canal), and bottled water (Van Norden 2007 by Sutton,
2008).
9
WHO, basic access can be defined as the availability of drinking water at least 20
liters per day per person, a distance of not more than 1 km from the source to the
house and a maximum time taken to collect round trip of 30 minutes. The UNDP
(2008) says the minimum absolute daily water need per person per day is 50 liters
(13.2 gallons) which include: 5 liters for drinking, 20 for sanitation and hygiene, 15
for bathing and 10 for preparing food. However because of scarcity of drinking water,
millions of people try to exist on 10 liters (2.6 gallons) a day (ADF, 2005). In densely
populated areas, a water hauling trip of 30 minutes or less, including queuing time
would be a more appropriate indicator of access.
As indicated by ADF (2005), over one third of women in some of the regions spent
more than two hours for each water collection trip. This fact is aggravated by the poor
supply efficiency, resulting from bad condition, which cannot satisfy the entire
populations from different villages sharing the same water source and increased
queuing time is common during the dry seasons (Admasu et al., 2002). This will
ultimately lead to household water insecurity (less water available than is needed for
drinking, cooking, and sanitation) in rural areas, especially for those households for
which the demand is higher due to large family size (Collick, 2008, as cited by
Demeke, 2009). Because of these conditions, it is difficult to think about personal
hygiene and sanitation especially for the rural communities. Despite the scarcity of
water, many give priority for drinking and cooking purposes. Rural communities use
unprotected springs and hand-dug wells commonly for cooking and drinking purposes.
Whereas rivers besides their use for washing clothes they also used for drinking
purposes.
This results in not only sickness and death, but also economic crises. Therefore, safe
drinking water is an essential component of primary health care and is vital for
10
poverty alleviation. Introducing improved water supply sources at the household level
enhance personal and community knowledge as well as awareness of the importance
of other factors, such as hygiene and sanitation (Sobsey, 2002).
2.2 Water quality parameters
Drinking water, or potable water, is defined as having acceptable quality in terms of
its physical, chemical, bacteriological parameters so that it can be safely used for
drinking and cooking (WHO, 2004). WHO defines drinking water to be safe if and
only if no any significant health risks during its lifespan of the scheme and when it is
consumed. This thesis focuses on water quality for drinking and domestic uses.
2.2.1 Perception of drinking water
In terms of drinking water quality, user perception is one of the most important things,
sometimes exceeding actual quality of water especially when it concerns the quality of
drinking water for the user communities (Sheat 1992, Doria 2010). There are different
factors that influence the perception of drinking water quality, including:
Human sensory perceptions of taste, odor and color of water are related with
mental factors and some extent taste, which is the more important because it may
detect water contamination related to chemicals.
People may perceive risks if they experience health problem caused by water.
Experience with the previous water source status based on its taste, color and
odor change. For example the change in the color of water from yellowish to
bluish may feel that the water is perceived not good water (Doria, 2010).
11
Information plays a great role in changing people‟s perception on the water
source behavior. It may be person to person or using media (like news papers,
brochures etc.) but in rural areas and poor urban residents interpersonal
information is important.
2.2.2 Bacteriological parameters
The diseases caused by water related microorganisms can be divided into four main
categories:
Water-borne diseases: caused by water that has been contaminated by human,
animal or chemical wastes. Examples include cholera, typhoid, meningitis,
dysentery, hepatitis and diarrhoea. Diarrhoea is caused by a host of bacterial, viral
and parasitic organisms most of which can be spread by contaminated water
(WHO, 2006). Poor nutrition resulting from frequent attacks of diarrhoea is the
primary cause for stunted growth for millions of children in the developing world
(Gadgil, 1998).
Water-related vector diseases: These are diseases transmitted by vectors, such as
mosquitoes that breed or live near water. Examples include malaria, yellow fever,
dengue fever and filariasis. Malaria causes over 1 million deaths a year alone
(WHO, 2006). Stagnant and poorly managed waters provide the breeding grounds
for malaria-carrying mosquitoes.
Water-based diseases: These are caused by parasitic aquatic organisms referred to
as helminths and can be transmitted via skin penetration or contact. Examples
include Guinea worm disease, filariasis, paragonimiasis, clonorchiasis and
schistosomiasis.
12
Water-scarce diseases: These diseases flourish in conditions where freshwater is
scarce and sanitation is poor. Examples include trachoma and tuberculosis.
Testing the bacterial contaminants in water can be simplified by utilizing the presence
of an indicator organism. An indicator organism may not necessarily pose a health risk
but it can be easily isolated and enumerated, is present in large numbers, is more
resistant to disinfection than pathogens, and does not multiply in water and
distribution systems (Gadgil, 1998).
Traditionally, total coliform bacteria have been used to indicate the presence of fecal
contamination; however, this parameter has been found to exist and grow in soil and
water environments and is therefore considered a poor parameter for measuring the
presence of pathogens (Stevens et al., 2003). Studies also show that due to their ability
to grow in drinking water distribution systems and their unpredictable presence in
water supplies during outbreaks of waterborne disease, the sanitary significance or
quality of water is difficult to interpret in the presence of total coliforms (Stevens et
al., 2003).
An exception is Escherichia coli (E.coli), a thermotolerant coliform, the most
numerous of the total coliform group found in animal or human feces, rarely grows in
the environment and is considered the most specific indicator of fecal contamination
in drinking-water (WHO, 2004). The presence of E. coli provides strong evidence of
recent fecal contamination (WHO, 2004, Stevens et al., 2003).
The risk of coliform presence can depend on the health or sensitivity of the consumer.
The risks of E. coli presence, slightly greater than WHO Guideline‟s zero count per
100ml may be of only low or intermediate risk. According to IRC, 2002 as cited by
13
Michael H., 2006 about risk classification for thermotolerant coliforms or E. coli of
rural water supplies shown below.
Table 2: water quality counts per 100mL and the associated risk
Count per 100ml Risk Category
0 In conformity with WHO guidelines
1 – 10 Low risk
11 – 100 Intermediate risk
101 – 1000 High risk
> 1000 Very high risk
2.2.3 Chemical parameters
Some of the main chemical parameters that are of a health concern include the
following WHO (2004):
Fluoride causes mottling of teeth and in severe cases can result in crippling
skeletal fluorosis.
The presence of arsenic implicates the risk of cancer and skin lesions.
Nitrate and nitrite can cause methaemoglobinaemia. This arises from excess
fertilizers or leaching of wastewater and other organic wastes into water surface.
Lead can have adverse neurological effects, mainly in areas with acidic waters and
the use of lead pipes, fittings and solder.
Secondary concern of the impact of chemical constituents is the effect on distribution
and treatment systems that may be implemented to improve the access to a safe water
supply. Corrosive properties of constituents can induce structural failure, which can
also result in deterioration of the quality of the water and cause additional concerns for
health and safety. Due to these concerns, corrosion control is an important aspect of
14
the management of a drinking water system. pH can control the solubility and reaction
rates of most metal species involved in corrosion reactions (WHO, 2004).
Iron, lead, copper, brass and nickel can also be used in construction of piping systems
(WHO, 2004). Concrete is a composite material consisting of sand, gravel and cement,
a binder consisting primarily of calcium silicates, aluminates and some lime (WHO,
2004). Structural deterioration or failure of cement may result from prolonged
exposure to aggressive or highly corrosive waters which can result in leaching of
metals from the cement into the water (WHO, 2004).
When ferrous iron oxidizes to ferric iron, it can give a reddish-brown color to the
water, which could be aesthetically displeasing (WHO, 2004). Manganese can cause
an undesirable taste as well as staining laundry when levels exceed 0.1 mg/liter. The
presence of manganese may also lead to the accumulation of deposits in the piping
system (WHO, 2004). There is no health-based guideline value set for iron but for
manganese it is four times higher than the acceptable threshold of 0.1 mg/liter (WHO,
2004).
2.2.4 Physical and aesthetic parameters
Consumer perception and acceptability of their drinking water quality depends on user
sense of taste, odor and appearance (Sheat 1992; Doria 2010). That is why consumers
have differing opinion about the aesthetic values of water quality. Relying on their
own senses may lead to avoidance of highly turbid or colored but otherwise safe
waters in favor of more aesthetically acceptable but potentially unsafe water sources
(WHO, 2004).
15
Taste and odor can originate from various natural chemical contaminants, biological
sources, microbial activity, from corrosion or as a result of water treatment (e.g.
chlorination) (WHO, 2004). Color, cloudiness, particulate matter and visible
organisms can also contribute to unacceptability of water sources. These factors can
vary for each community and are dependent on local conditions and characteristics.
The following lists a number of primary aesthetic indicators that can cause water to be
perceived as unacceptable:
True color (the color that remains after any suspended particles are removed);
Turbidity (the cloudiness caused by particulate matter present in source water, re
suspension of sediment in the distribution system, the presence of inorganic
particulate matter in some groundwater or sloughing of bio-film within the
distribution system (WHO, 2004).
unusual taste, odor and „feel‟ problems (usually due to total dissolved solids)
Turbidity is the most important problem for the aesthetic value of water quality.
Although it doesn‟t necessarily adversely affect human health, it can protect
microorganisms from disinfection effects, can stimulate bacterial growth, and indicate
problems with treatment processes (WHO, 2004). For effective disinfection, median
turbidity should be below 0.1 NTU although turbidity of less than 5 NTU is usually
acceptable to consumers (WHO, 2004). An important operational water quality
parameter is pH, although within typical ranges it has no direct impact on consumers.
Low pH levels can enhance corrosive characteristics resulting in contamination of
drinking-water and adverse effects on its taste and appearance (WHO, 2004). Higher
pH levels can lead to calcium carbonate deposition. Careful consideration of pH is
16
necessary to ensure satisfactory water disinfection with chlorine, which requires pH to
be less than 8 (WHO, 2004).
Total dissolved solids (TDS) and electrical conductivity (EC) are measures of the total
ions in solution and ionic activity of a solution respectively. As TDS and EC increase,
the corrosive nature of the water increases.

3 MATERIALS AND METHODS
3.1 Description of the study area
The study area Simada is part of South Gondar Zone found in one of the nine regional
states Amhara region, which is situated 774 km north of the capital city of Addis
Ababa and 209 km southeast of Bahir Dar (figure 1). The topographic elevation ranges
from 1196 meter above sea level (m.a.s.l) to 3525 m.a.s.l. It is bordered on the
southeast by the Beshilo River which separates it from the South Wollo Zone, on the
southwest by the Abay (Nile) which separates it from the East Gojjam, on the
northwest by Este, and on the east by Tach Gayint. Part of this district‟s boundary with
Este is defined by the Wanka, a tributary of the Nile. The major town of Simada is
called Wogeda.
The district has three climatic zones: 40% woynadega (intermediate elevation), 10%
dega (high land) and 50% kola (low land). The urban center where 5% of the
population lives in the district is located in the Woynadega zone.
The climate is monsoonal and varies with elevation. The primary wet season extends
from April through October; among these, July and August are the wettest months.
The mean annual rainfall is 900-1100mm and the mean annual temperature is 23oC.
According to the Central Statistical Agency, 2007, the district has an estimated total
population of 228,271, an increase of 22% from the 1994 Census. This is an average
of 4.2 persons per household. The population density of 102 persons per square
kilometer is less than the zonal average of 145 people per km2.
18
Figure 1: Location of Simada Woreda in the Amhara Region
There are 39 peasant associations of which 15 are found in the woynadega, 4 in the
dega and 20 in kola.
The farming system of the district is mainly mixed cropping system which is
dependent on both crop and livestock production. The total area of the district is
228,172 ha; out of this, cultivated land and land gone for grazing are 68,111.22 and
21,445 ha, respectively.
3.1.1 Water supply
Over the past years, many water supply projects were built by different governmental
and nongovernmental organizations. All of the implementing organizations were
19
concerned with rural water supply projects and followed their own approaches based
on their project interests. Some involved the local communities and needed
contribution from the direct beneficiaries while others cover all the construction costs.
At present 68% of the urban population receives water from improved sources. Fifty
percent of rural population is covered by improved water supply system.
In the district, there are 328 water points: 189 hand dug wells (HDW), 124 developed
springs (SPD) and 15 shallow wells (SHW), of which 23 HDW and 10 SPD can be
repaired, while 12 HDW, 11 SPD and 3 SHW need expensive renovation (Table 3).

In the urban area there are 250 individual pipeline connections and 11 public stand
taps. The technicians report that one tap supplies 500 people. At the time of the
survey, the residents paid 1birr for 5 Jeri cans. After March 2011 the price decreased
to 8 Jeri cans per birr to make it more affordable to the poor. These water points and
year of construction is shown in Table 4 (rural water points).

3.2 Data collection methods
Mixed method data collection was carried out during the survey period. The selection
of the area was grouped into two major classes or regions of rural and urban areas,
with the rural areas further divided in to market centers and non-market centers
(villages). Because of the variation in many circumstances such as their living
standards and accessibility of facilities, using these two groups to represent the rural
settings equally was important. Villages are rural settlements without market or any
public facilities whereas market centers have a minimum of public facilities like
markets, shops, high schools, health centers and others. A stratified random sampling
technique was adopted to select the sample needed for the study. Therefore each ward
used as a sampling frame was identified as urban areas, rural areas with market centers
and rural areas without market centers. As a first stage the water points were selected
from each ward, having seven from rural market centers, six from rural none market
centers and three from urban site. These water points were selected randomly and gave
us a total of 16 water points for both the rural and urban regions.
In the second stage household heads were selected for interview. The sampling
methodology was determined from Arkin and Colton (1963) as cited by (Bhandari,
21
2007): the sample size determined the expected rate of occurrence as not less than
90% at 95% confidence level with a precision level of 3%.
𝑛 =𝑁𝑍2 ∗ 𝑝 ∗ 1 − 𝑝
𝑁𝑑2 + 𝑍2 ∗ 𝑝 1 − 𝑝 Eq. 1
where n is the sample size, N is the total number of households, Z is the confidence
level at 95% of Z = 1.96, P is the estimated population proportion of 0.5 which
maximize the sample size and d is the error limit of 5% which is equal to 0.05.
As a result, 76 respondents out of 849 beneficiaries from rural market centers, 40
respondents out of 357 beneficiaries from non-market centers and 44 respondents out
of 443 urban areas were selected from the list of beneficiaries obtained from the
respective rural water supply offices. This comprises sa ample size of 160 respondents
randomly selected from the total of 1,649 beneficiary households.
In the third stage, for the primary data collection the household heads (especially
women who are responsible for water collection) were interviewed. The instruments
of the research were structured and semi structured questionnaires and open-ended
discussions with the communities and water use committees. Essentially cross-
sectional primary data was collected from households about their water use practices
and water quality perceptions. In addition to that data on socio-economic, water
utilization characteristics and household determinants of collecting water from
improved water sources were gathered. For the accuracy of the measured values such
as distance from the source to the house, time taken to collect water, average slope,
elevation and locations were taken from the GPS readings by averaging the center of
the inhabitants‟ location to the water source. Secondary data were collected about
water source protection from the concerned experts, rural water office and water use
22
committees. Besides that on site observation about the status of each water point were
completed.

3.2.1 Water Sampling
Water samples were collected from different sources of water used by the
communities in rural and urban sources. A total of eleven water samples were
collected for laboratory analysis from which three samples were from urban and a total
of eight samples were from rural areas. In addition, samples were collected both from
improved water sources and unimproved nearby alternative water sources currently
23
used as main sources for household consumptions. However the distance covered
between these sources ranged from 40 meters to 700 meters. The samples collected
from unprotected springs, protected springs, hand dug wells and urban tap water were
sent for analysis to regional water quality laboratory by coding them as shown below
Table 6. Based on the water quality of the samples investigated, the status of the
existing water quality was compared with the standards of the world health
organization (WHO, 2004).

3.3 Data analysis
Identifying the number of factors that forced user access to water sources, reluctance
to use improved water sources, and their perception on water sources quality are
investigated. Based on this, the data was analyzed using descriptive statistics, linear
regressions and chi square test using SPSS software system.
The chi square test was used to analyze if there is an association with reluctance to
collect water from improved water sources vs. unimproved sources with other
25
variables. To test the hypothesis of independency of two attributes, the chi square test
is commonly used. These variables include distance from the source to the house,
waiting time, quality of the sources, adequacy of water, presence of alternative sources
in the vicinity, income, personal interest and other factors. These factors influence
households to participate (collecting) water from improved water supply sources.
Waiting time to fetch water from the source, distance from the source to house,
existence of alternative source around the vicinity of the existing water source and
income obligate the community to seek unimproved water sources in place of paying
for improved sources. In addition, the quality and adequacy of the water also had its
own contribution. The waiting time, distance from the source to house and adequacy
can be interpreted in reference to WHO (2004) standards of 15 min, 1.0 km and 20
l/d/p respectively.
The χ2 (chi square) statistic is given by the formula:
x2 = Oij − eij

Where: Oij is the number of units that belongs to the category of i of reluctance and j

reluctance and j of the other variables
The eij is given by
eij =Ri ×Cj

The null and alternative hypothesis may be tested as H0: no association between
reluctance to collect water from improved sources and other selected variables and H1:
there is association between reluctance and other variables.
The decision rule states to reject the H0 for independency at level of significance if the
calculated value of χ2 exceeds the tabulated value with degree of freedom equal to (r-
1) (c-1).
The water use patterns of the community within a given water source vary from one
house hold to another in both urban and rural areas. The major determinants for the
water use (both total household and per capita water) include household size, income,
distance from the source to the house, education level and queuing time.
These independent variables in the water use behaviors were identified based on
published literature and the actual conditions in the area useful to explain the
variations on the dependent variables. Linear regression model was selected to analyze
the relationship between these variables. The equation used the linear combination of
variables X1,X2,X3,……Xn which was presented as Z=B0+B1X1+B2X2+….+BnXn
where Z is the dependent variable per capita water consumption, B0 is a regression
constant, B1, B2, Bn is the regression slope or coefficients of variables and X1-Xn is
the independent variables.
In the present context X1 is total family members, X2 is education level, X3 is total
household income, X4 is average queuing time and X5 is average distance covered per
round trip.
27
Quality of the water source was based on the perception of the households during the
survey and the laboratory results obtained by the quality tested from selected water
sources.
Water quality analysis was used to present the household perception of water quality
both in rural and urban areas and following the results of the laboratory tests as
compared with the WHO standards. Questioners were used to obtain information
basically from women who took the greater responsibility of water collection and
asked about the consumed water quality perceptions on color; taste and odor during
data collection employed.
For the analysis of water quality the main water quality indicator parameters were
detected from the laboratory including physicochemical and bacteriological quality.
The physicochemical parameters included: electrical conductivity (EC), PH, TDS,
turbidity, nitrate, nitrite, iron, manganese and residual chlorine. Turbidity, an
important indicator of water quality as it can protect bacteria and viruses from
disinfection, is also a good vector for the introduction of Giardia and Cryptosporidium
cysts in drinking water system (Ando, 2005). In addition, bacteriological parameters
including total coliforms and fecal coliforms were analyzed using filter membrane
technique by incubating the membrane on a growth promoting medium for 24 hrs at
37oC and 44.5
oC, respectively, and counting the resultant colonies per 100ml of
samples collected from both improved and unimproved sources. Consequently it was
important to compare the quality of the water which is directly used for drinking
purposes from these two water sources.

CHAPTER FOUR
4 RESULT AND DISCUSION
4.1 Socioeconomic characteristics of respondents
The socioeconomic characteristics of the respondents are shown in Table 7a-e below.
The table presents the respondents distribution by presence of spouse of household
(Table 7a), sex (Table 7b), educational background (Table 7c), age (Table 7d) and
finally a summary of total household income from crops, livestock and non-
agricultural products (Table 7e). The age range in urban area was 45.5 percent are
between 20 and 30, 38.5 percent between 31 and 45, 14 percent between 46 and 60
and 2 percent above 60 years old with 35 years of average, 20 years of minimum and
64 years of maximum. In rural areas the age range was 38.8 percent are between 18
and 30, 40.5 percent between 31 and 45, 16.4 percent between 46 and 60 and 2.6
percent above 60 years old with 37 years of average, 18 years of minimum and 85
years of maximum. The results show a wide range of age proportion of the sampled
respondents, which was good because it increased the likelihood of capturing and
understanding community perception about water consumption behaviors and
perceived quality of the source. Of the sampled respondents, 39 percent of the urban
and 57 percent of the rural had spouses. Female-headed sample households were 82
percent from the urban and 69 percent of the rural. These large percentages of female
respondents were because of two reasons:
1) The data had been collected during meker (crop harvesting season) when farmers
were busy on field works, so that females stayed to be interviewed.
2) It was women who suffer the burden of fetching water hence the study gave strong
impression to sense the majority of their number. Because of this, the full
29
participation of women in such development programs was crucial and could give
the real problems and proposed solutions concerned about water issues.
Furthermore the survey results revealed that about 57 percent of the urban and 66
percent of the rural respondents have no education or were illiterate while 23 percent
of urban and 15 percent of the rural could read and right or have informal education.
Even though the higher percentage of the respondents was illiterate they had their own
perception to understood the status of their water source service status and also its
quality. The average household size was about 3 for urban and 4 for rural while the
maximum household sizes were 7 for urban and 8 for the rural areas, respectively.
The mean, minimum and maximum amount of each household income from non
agricultural, crop production and livestock production are shown in table 7d. The total
income source of the house hold show that with an average of 2,252 birr and a
maximum of 10,200 birr in urban area while 3,505 birr of average and 20,950 birr of
maximum in rural areas. The income median value was taken because it is
recommended to use median value when the difference between minimum and
maximum values is too large.

4.2 Household water consumption
The household water consumption behavior under this study determines those primary
and secondary or alternative water supply sources. Despite to deal with household
water consumption from improved sources, unimproved secondary sources were
included. Consequently from the total households interviewed about 77% of the urban
and 65 percent of the rural areas had one or more alternative water sources. Along
with 45% were unimproved sources. Women and children were the main responsible
household members to collect water. Hence 70.5% of women and 18.2% of both
women and children from urban and 45% of women and 40% of both women and
children fetch water in rural areas.
Water collection material was the most important component for women and children.
As a result of that clay pots and Jeri can4s were the two most common types of
materials. Thus in the urban area about 95.5% used Jeri can and the rest both Jeri can
and clay pot whereas in the rural areas 80% of Jeri can, 13% of clay pot and 7% of
both clay pot and Jeri can are used. It was issue that women carry heavy loads to
collect water from moving up and down steep slopes. Accordingly the study revealed
that respondents travelled about an average slope of 6% with a minimum of 3% and
maximum of 17% slopes. These slopes considered only those the initial and final
records from the source to the average location of the residents. Besides this
individuals travel frequently up and down many continuous slopes between this
ranges. But introducing Jeri-can has two advantages in such locations. First: it reduces
the burden of carrying heavy container as it is made from light material. Second: it
4 Jeri can is a plastic material used to collected water instead of using clay pots, which mainly can
contain 20 or 25 liters
32
minimizes possibilities of post contamination as water is used by tilting the Jeri can
instead of dipping cups. Studies had shown that the level of water contamination is
high at the point of consumption than the point of collection (Tiku et al., 2003) which
may be attributed to the mode or drawing water from the containers. This was the best
result of the health extension work throughout especially in the rural villages since it
was one of the 11 sanitary packages.
Frequency of water collection from improved sources and unimproved sources on
average was 1.2 times for the urban and 1.5 times for the rural (Appendix table 15). To
observe the difference between the urban and the rural areas access to water supply
using distance cover, time taken and queuing time were discussed below. Based on
that the average maximum distance covered from the two sources of 1340 meter, 4.36
total hours spent per week per person and 1hour mean queuing time taken to collect
water from improved sources were obtained from urban area. In contrast the rural
areas of 2430 meter average maximum distance covered from the two sources, 5.74
total hours spent per week per person and 1.5 hours mean queuing time taken to
collect water from improved sources were higher than in urban areas. From this it is
possible to say that the urban water supply systems were better off than rural water
supply systems. According to the study the result respond beyond the threshold level
of World Health Organization (WHO) (2004) standards. Concurrence to WHO (2004),
such sources categorized under unhealthy or unimproved sources recommendation by
WHO, 1km distance cover, 30 minutes time taken with queuing time and 20 liters of
per capita water consumption. The queuing time taken to collect water from
unimproved sources in urban areas was 1.52 which is greater than 1.3 for rural areas.
The main reason for that was the availability of unimproved sources in the vicinity of
rural areas was more accessible than urban areas.
33
The per capita water consumption in urban areas was 13 liters better than 11 liters
from rural areas. Even though less difference is there, in urban areas the use of water
is not only for cooking and drinking but also the rate of use of water for sanitation and
hygiene was lesser in rural areas.
Whereas the average total time spent per person per week was 4.36 hours for urban and
5.74 hours for rural areas on average of 5 hours with a maximum of 21.47 hours. For
comparison, according to Roy et.al (2005) and as sited by them under World's Women
(2000) reporting data from the UN statistical office, that water collection times in Kenya
was an average of more than four hours in dry seasons and two hours in wet seasons. In
addition, four to six hours were necessary to collect water in Burkina Faso, Botswana
and Cote D‟Ivoire (Roy et.al (2005). And water collection times of 17 hours per week
for Senegal and 15 hours for the dry season in Mozambique. This took only the time
taken to collect water from the source to the house but when it includes the queuing time
according to the definition of access to improved water sources, the time taken exceeded
5 hours which was about 13hours. Thus the report from the study area was similar to the
study in western Kenya.
In addition, the average total amount of water consumed by the household was 32
liters for urban and 36 liters per day for rural areas. But the per capita water
consumption in urban areas was 13 liters per day per person better than 11 liters per
day per person from rural areas. Even though less difference is there, in urban areas
the use of water is not only for cooking and drinking but also the rate of use of water
for sanitation and hygiene was lesser in rural areas.
This result was also below the threshold level of WHO standard (20 liters per day per
person). Whereas this result met with the reports found from ADF (2005).
34
4.2.1 Determinants of per capita and total household water consumption
The regression results of the comparison of the households‟ per capita water
consumption from urban and rural areas are available in Table 8. When there is an
increase in household size, the probability of collecting more water for larger
household size than individual household. As a result, there is a positive relationship
between household size and total water consumption. However, the per capita water
consumption decreased with an increase in household size because there is a problem
of access and adequacy when considering the supply necessary to meet the needs of a
large family. Family size had a negatively to per capita water consumption both in
urban and rural areas. This implies that there was a negative relationship between
household size and per capita water consumption. Therefore for every one unit
increase in the household size there is a decrease in the per capita water consumption
by 1.9 times in urban and 1.7 times in rural areas. In other words all household
members share the available water less than single individual access per day. In
addition to that average queuing time was also significant factor for urban areas which
was negatively correlated with per capita water consumption. Hence, for a unit
increase queuing time there was also a decrease in per capita water consumption by
4.2 times. Because the more the queuing times the less to access the required amount
of water for daily consumption.

a. Dependent Variable: Per capita water consumption
There were people who are still dependent on unimproved water sources. such that a
cross tabulation chi square test were run to saw the association between people
reluctance to collect water from improved sources and factors that assumed to trigger
this reluctance. The following table 9b shows us income and waiting time were the
two variables significantly affected in urban areas. In contrast to the rural areas table
9a income was not a factor. Because people in rural areas were not willing to pay for
improved water services whereas, in urban areas especially the poor who were unable
to pay for the tap water owned by municipal water service enforced to search
alternative unimproved sources. Beside that queuing time was also a problem to access
water hence people obligate to found alternative unhealthy water sources. In rural
36
areas distance from the source to the house, quality of the water, adequacy from the
source and waiting time were significant at P values less than 0.05. This means there
was a relationship between reluctance and these variables. Because when the distance
from improved sources increased people prefer to collect water from nearby
unimproved sources. Even though distance was a reason, waiting time undermine to
travel long distances to access the water any where coupled with lack of adequate
amount of water availability. Sometimes household prefer to collect water from
unimproved sources because they believed the water sources can be cleaned manually.
The reason behind was less attention given to treat the improved sources by the water
office technicians once installed.

There were different systems the community used to manage and evenly distribute the
existing improved water sources for all households include:
37
Setting fixed time to collect water twice a day mostly from 7-9am and 4-6pm.
Classifying the total households in to groups per day. If other groups need to
collect during that day it was must to search alternative unimproved sources.
Putting a predetermined amount of water collected per day per household, such as
four Jeri cans per day per household.
Increasing the rate of payment per month for those who came outside the territory.
E.g. for the owner of the scheme 1birr per month while 7 birr per month for
outsiders (1 US dollar =16.69 birr in Ethiopian current exchange).
Categorizing the water sources services as drinking from improved sources and
cooking and personal hygiene from unimproved water sources.
Hiring guards and constructing fences was also the best option to avoid conflicts
and for equal distribution of water without discrimination.
Construction of alternative nearby improved water points create an opportunity to
avoid water related disease particularly for aged people who depend on proximate
unimproved sources.
Many people collect water at midnight to reduce the waiting time from both
improved and unimproved sources.
Both sources are located near improved sources at a distance of about 40m and 100m
respectively. At UP18 improved sources were visible that people did not using it
rather depend on unimproved source. Whereas UP32 shows people whose group turn
was out of the date searching the water from unimproved nearby improved sources.

4.3 Water quality perceptions
Consumers concerning their drinking water said aesthetic factors such as taste, odor,
and color were very important. Likewise the drinking water trustworthiness depends
on the perception of consumers and the resultant complaints due to tastes, odors, color
or any other particulate matter.
4.3.1 Aesthetic parameters
All water samples taken from improved and unimproved sources were tested for iron
and manganese. From the total water samples analyzed for iron, one improved sources
and 75% of unimproved sources in the rural areas did not met the value suggested by
WHO for the acceptability of drinking-water (0.3 mg/l). According to the UNICEF
(2008) hand book on water quality may be the level of contamination influenced by
the depth of the water sources whether or not it is capped. The remedial action if the
39
aquifer is affected also to tap another unaffected deeper aquifer or use another source.
Since the depth of improved sources is deeper than unimproved sources (mostly
natural springs) the concentration of iron is lower. In addition to that the manganese
test result of improved sources 57.2% and 75% of unimproved sources also did not
meet the WHO (0.2ml/l) standards. Manganese is the main source of displeasing test
and consumes much detergent when used for washing. From the following table 11 it
was certain that the water source sample P18 which was improved hand dug well
accounts the greatest number of manganese above the threshold level which is
5.3mg/l. As a result of this the existing households were not used from this source due
to displeasing test of the source. But they used for washing clothes mostly people did
not use soap rather they wash without soap or traditional means. Because of this
reason they were dependent on the alternative nearby unprotected spring which
measures 0.33 and 0.8mg/l iron and manganese respectively. The rural peoples mostly
used to wash their clothes at streams and rivers than water supply schemes. This P18
source was unique than other sources which had alternative unimproved sources serve
as the main sources additionally. It is observed that the color of water is changed into
reddish and people said the reason may be the presence of cattle trough spring
approximately 10 meters from the head of the well causes the problem. In contrast
three of the urban sources met the recommendation for iron and manganese. To
compare these results with the direct survey conducted from total households 6.8% of
the urban and 2.6% of the rural improved sources color is not good. The color
complain from urban improved sources was resulted from tap water which had a better
chance to treated with chlorine so that consumers believe it is not palatable directly
unless waits for some time to settled. Consequently the laboratory result shows the
presence of chlorine residue of 0.3mg/l only from tap water which was within the
WHO recommendation (2.5-0.5mg/l). But the residual chlorine is good and should
40
always be maintained so that even post contamination due to presence of bacteria in
the water collecting vessels could be avoided.
In addition to that due to corrosion of iron pipes and stand pipes in the distribution
system, the color and test of the water may be affected. According to the survey result
from the two areas 64.5% of the respondents believe that test was the main indicator
of water quality deterioration. It was proved that test of water is the main indicator of
aesthetic water quality status (Dietrich, 2006). These parameters adopted well and
some of the community member‟s especially Muslim religious followers said that
“quality water should full fill these three (i.e. test, color and odor) parameters or could
not be used for any purposes” learned from their religious lessons. If these parameters
fulfilled it is believed to be quality water. Using taste as the main indicator of water
quality perception and determining the perceived test of improved and unimproved
sources, 7% of the urban and 18% of rural households respond and believe that the test
of improved sources were not good while 32% of the urban and 13% of the rural
perceived the quality of unimproved sources were good and better than improved
sources.
However the urban households believed the test of alternative protected spring was
better than the tap. They explain that spring water was better because it flows day and
night directly from the spring eye and consequently there was no time for bad
materials to left in the water. In contrast the tap water flows through pipe which heated
with sun light and chlorination creates disturbing taste of water (Dietrich, 2006).
The surveyed respondents believe that the major source of change in the taste of water
was flood. As it was observed many of schemes were located nearby gully formations.
As a consequence 61% of the urban and 52% of the rural areas believe human waste
41
was the major causes of water quality deterioration. The main reason for improved
sources pollution by humans was: especially in rural areas children play on water
sources particularly on hand dug wells. In addition to that destruction of cement well
of the scheme and the residual water caused by over flow after the collection material
was filled enter back in to the source. Furthermore most of the improved water sources
located along the main roads so that it makes the scheme susceptible for pollution like
people wash their hands and heads over it and their waste enter into the source through
openings. Whereas in urban areas since the main source of water located downstream
side of the residents where open defecation was common in the upstream locations.
From the total water samples tested for turbidity, 71% of improved and 25% of
unimproved sources met the recommended value of WHO that is 5 NTU in the rural
areas. The higher percentage of the unprotected sources was mainly caused by the
runoff during rainy season and blowing of particulate matter over its unconfined
surface which pollutes and increases the turbidity of the water. Whereas for improved
sources mostly turbidity was caused by like a hand dug wells, when the stored water
pumped out the pump disturb the whole water body. In addition to that flood enter in
to the water tankers and children‟s play over the scheme and drops dirt particles into
the water. In contrast the urban sources were below the recommendation of WHO.
Electrical conductivity (EC), pH, nitrates, nitrites and TDS from the two areas were
within the recommended ranges by WHO. A TDS of less than 600 indicates good
palatability (WHO, 2004), and all the samples from this study were palatable.
Chlorine concentration in the urban tap water was in recommended WHO range of
0.25-0.5mg/l. Chlorine was added in the urban springs and tap water 4 times per year
42
and it can treat itself. As expected all rural water samples were less than 0.25 mg/l
(Table 11).
4.3.2 Biological parameters
The urban springs from which the tap water originated and are being used by people
for drinking water was contaminated with coli form since the tap water was free of
fecal coli form it shows that the chlorine application for the urban tap was effective
and the test results had 0cfu/100ml. In contrast all water from both protected and
unprotected had fecal coli from counts in excess of the WHO standard (table 11).
According to IRC (2002) as cited by Michael H., (2006), Risk classification except the
urban tap water other sources indicates the incidence of faecal coli form which could
be classified under low (42.9%), intermediate (14.3%) and high risk (28.6%)
classifications. The two urban springs included under low risk classification. Table 10
summarizes improved and unimproved water sources of total and faecal coli forms.

4.3.3 Treatment measures used
The treatment measures adopted from the different locations of the people vary
accordingly. According to the following Figure 4, the survey result showed 85% of the
urban and 86% of the rural respondents did not use any treatment measures. Since the
main source of water was improved sources for this study bench mark and many of the
people assumed the water sources once protected so no risk was expected. And the
urban residents believed that once the water treated by chlorine there was no problem.
But a significant number of people used Aqua tab, boiling and sedimentation as
treatment measures. From the total number of respondents 10% of the urban and 2%
of the rural used to treat using boiling techniques. Traditional techniques were also
adopted like smoking and washing the container with a special wood, plant leaves and
sand. Because they thought that it could increase the better test of the water and killed
the remaining pathogens within the container. But it needs especial attention and
extension works to enhance people‟s attitude to use different techniques.

4.4 Sanitation and hygiene
Environmental sanitation is essential to promote health and prevent diseases. It is
described in terms of personal hygiene, toilet facilities and surrounding environment.
Water supply conditions without sanitation and hygiene behavior looks nothing
(Water Aid, 2009). According to the report found from the expert in the study area, the
sanitation coverage shows 49.5% of urban and 16.8% of rural areas which is still
underestimated so that it needs more focus. Besides that out of the total sample
households only 27% of the urban and 39% had accessed to latrine facilities such as
simple pit latrines. Not had these latrines but also 46% of the urban and 71% of the
rural currently use the latrine and out of which 28.9% of children did not use the toilet
from the two areas. Plus the condition of toilets was also not so hygienic due to
scarcity of water and problem of awareness created among the existing households.
The local communities‟ awareness toward sanitation seem good and got access to
sanitation and hygienic education especially in rural areas but analyzed at ground in
terms of their practices became limited. The members of the households without

toilets go to nearby open field for defecation. According to the survey results 84
percent of the urban and 77 percent of the rural respondents defecate from open fields.
The reasons for not having toilets included adopted habit of preferring to open field,
absence of space or land for toilet and lack of labor and money. This reasons
developed from two major categories. First lack of awareness made the people to
prefer open fields and lack of money and land related with poverty. Particularly in
rural market centers the home owners needed to construct its free land for extra rented
house than digging latrine. But there were some individuals who had awareness about
their environmental sanitation as a result of that one respondent said that “It is nothing
if I dig a pit for latrine unless my neighbor do the same because his children defecate
on the garden so that the flies bring the disease to affect my children easily‟‟. In close
proximity, open fields and riverbanks were the two major places used by households
for defecation. For the rural communities they used their toilets during the wet season
because their fields occupied by crops. While the urban poor and peripherals
inhabitants did not have latrines travel long distance to defecate under river banks. The
main thing here was the rural non market center people did not allow the market center
residents and also for the urban peripheral to use their lands to secure from crops
trample. Table 12 below shows that the percentage of having latrine coverage and
extent of use. The basic reason behind was the urban and rural market center residents
were mainly lived in rented houses so that the owner of the house did not willing to
construct the latrine. The rural areas had ample land and there were strong and better
extension done for the community than the urban extension workers lately takes into
service.

Information was also gathered on hand washing practices after defecation. There were
three different hand-washing practices observed such as soap, ash and water. It was
encouraging that majority of the households (95.5%) have used to wash their hand
after defecation. It was common for all the households to wash their hand after
defecation especially for the women who are responsible for the home work. In
addition to that it was common culture to wash hands before and after eating in
Ethiopia. There was also a good habit and chance of cleaning hands with water at least
five times a day in Muslim religious followers. It may better to further assess the
difference in rate of contamination among these people and other non followers.
4.5 Characteristics of water sources, their functionality, level of
protection and surrounding neatness
It was observed from the field about the characteristics of each water point status
during the survey period. The type of water sources coverage from the sample water
points were 56.25%, 37.5% and 6.25% of developed springs, Hand dug wells and tap
water sources respectively. With regard to each water supply scheme the minimum
number of beneficiaries of 171, a maximum of 1170 and an average of 426 were
recorded. The big difference of beneficiaries per schemes forced the water office to
build additional water points in the vicinity of developed sources. About the total
water point 37.5% of which had alternative improved water sources within the
distance of 20-300 meter interval. The oldest water sources (developed spring) were
developed during 1989 constructed by FHE from the rural area. In addition, the level
48
of functionality of the schemes in urban area; well functioning tap and with some
breakages of the two developed springs. On the other hand, in rural areas include
43.75% well functioning, 50% functioning with some breakages and 6.25% of non
functional at all. However, there was also scheme which was included under well
functioning source but it was not used currently by the existing households because of
its displeasing test that is P18. While most of the some breakages, revealed that from
developed springs of failure of faucets and valves. The major reason for that was life
span of the valves and technical problems of using the faucets by the users which
couldn‟t operate properly according to the project expert from FHE.
The surrounding neatness of the water points were also observed in such a way that
from Table 13; 58%, 23% and 19% of the total water sources including both protected
and unprotected sources had not neat at all, somewhat neat and neat surroundings
respectively in rural areas. Beside that the neatness of the improved sources alone was
also tried to identify and 37.5% of each not neat at all and somewhat neat while the
other percentage lied under neat surrounding. But the urban sources were all
somewhat neat. Because discussing about the neatness of the surrounding could affect
the quality of the water source directly or indirectly. There was evidence that due to
problem of the neatness of the surrounding one scheme of hand dug well became
nonfunctional at all due to upstream side of the source neatness. In addition to that
neatness of the sources verified with the stagnant water due to poor drainage causing
water related disease (WHO, 2006), waste water enter back in to the source, bad smell
caused by lack of removing mud, growing algae and grasses and livestock waste
(Demeke, 2009). The following figure shows as some of the schemes characteristics.
49
Figure 5: Sample water sources with stagnant water (P35, Meramie; P22, Tach Ziwa
and P11, Lay Duba)
It was observed that all of the unprotected alternative water sources were not protected
at all but to protect the source from direct contact to animals and children it was
common that roofing the scheme with wood or stone. Whereas from the total sampled
improved water sources about half of them were not protected at all while the rest 23%
somewhat protected and 27% were well protected. Protection includes fencing, hiring
guards and locking for timely harvest. Beside that except one protected spring from
the urban, all of the other sources did not have additional facilities. According to the
district experts such facilities constructed based on the potential of the source and
budget availability.

4.6 The discrepancy between actual and reported access to
improved water sources
Accessibility of water supply points principally supplying adequate and quality water
for the wellbeing of human health. Sustainable Access to improved and safe drinking
water is one of the MDGs goals. Whereas the level of determining whether the
existing community got access to improved and safe drinking water was difficult to
know the exact value. According to USAID, 2006 Ethiopian report; the government
report that the percent coverage of water supply was 40% while NGOs and WHO said
the coverage approaches to 22%. Such disparities came from the absence of real data
and method of access coverage determination. Based on this fact it was tried to know
the exact access coverage of improved sources in the district had been gave two
answers. The first calculates the standards followed by each type of water point
potential to cover a significant number of beneficiaries. For example developed spring
(350), hand dug well (250) and shallow well of (500) beneficiaries per scheme. The
standard level of service is based on consumption of 20 l/day and maximum walking
distance of 1 km from the water sources (though this changes to 3 km in the arid
regions where the current distances are as high as 10 km in some instances), and
reduction in collection time to about one hour (ADF, 2005). Despite this points were
considered; the percent coverage of this technique always brought greater number.
The second actual number of people having access to water can also be determined
from the data available in the district office. By summing the actual number of
beneficiaries of the water supply systems is 27%, almost half of that reported from
standard based.
53
Standard rates of beneficiaries access water point was optimistic but because of low
populations density and the time it takes for walking to the water supply is much
greater than obtaining the water from a unprotected source that is closer.
Even though the above reasons challenge the real access to improved sources; some of
the people complain about the potential of the water supply scheme. The main reason
was: the technicians did not found the right spring eye so that its potential decrease
from time to time and the people forced to use unimproved sources. But the water
office experts believe that before five-six years ago such problems were prevalent so
that they were not willing to allow for the installation of improved water sources but at
present there were better awareness of improved sources than unimproved sources.
It was worth to discuss access to water supply, especially in regards to the MDG goal
point of view. Besides coverage, the sufficiency and quality of the installed improved
sources must also be considered in the discussion on access. Assuming that access to
water source coverage reaches the actual beneficiary number (27%) and whether it
was good or not. However, it was difficult to confirm this value because of different
reasons according related to the field observation and surveys conducted:
1) About 68.1% (77% of urban and 64% of rural) people depend on alternative5 water
sources of both improved and unimproved sources out of which 46% were
dependent on unimproved sources (Table 14).
5 Alternative water sources are those water sources used as additional water supply
points.

2) About 8% of improved sources were not gave the current supply of water due to its
lower quality than unimproved sources from the rural areas.
3) The functional level of schemes according to the district data shows about 10% of
improved sources were non functional.
4) Lack of maintenance for the existing water sources. As a result 29% of the
improved water sources affected by waste from over flow water enter into it. They
said that “We know the problem but we couldn‟t have option to leave the source”.
5) Low level of attending the healthiness of the sources. No water source treated with
any disinfectant after construction period completed.
Access coverage on the district expert point of view: disagree that determining the
coverage using the standard techniques. The main reason was if the value of the
standard number took as an accomplishment and struggle for 100%; after a while
almost 50% of the community will become out of any access reference to actual
numbering.
This paper disagree the determination of standard based type of access to improved
water sources coverage especially for those rural people residents. Because the people
inhabited pattern of scattered nature exacerbate the problem. So that a great attention
55
should be given for such issues before blocking part of the community without
improved supply of water and for the better success of the MDG Goal.
4.6.1 Accepting to pay for improved water sources
According to the survey results, households accepting to pay for the improved sources
account for 68% of the urban and 88% of the rural, while the others were not
accepting to pay. The main reason why people did not pay was mainly aged people
and poor people. Because they perceive and said that a women “from all my age I had
not been observed such payment, water is the gift of God, how could it be sold” and
the urban poor prefers to search other sources than paying for water. But it was
possible to observe the better attitude of the community regarding greater number of
the respondents were accepting to pay for the service and more than half of them were
aware of their responsibility for the schemes. If so why the rural people were not
paying for the service? It may be the institutional arrangement from the top to the
grass root level and the loose attitude of the selected water use committee did not
brought the people to coordinate and make responsible for the scheme. Because the
bylaws developed by the community should have recognition and legal within the
district level so that no body irritate to enforce their laws. There needs to create a
smooth relationship among the community and the water use committees.
It was important to saw the relationship between the adequacy and perceived safety or
quality of water sources with households‟ willingness to accept to pay for the
improved sources. Figure 6: shows there were a better percentage of acceptances to
pay for the quality water for those responded not safe at all, somewhat safe and
partially safe.
56
Bank report by Sara and Katz (1997), that when the communities perceive their water
shows a significant improvement they are more willing to pay for the service that is
for quality water. But at the safe and highly safe level perception the households‟
willingness to pay reduced. The reason may be since they perceive once their source is
safe, they did not want to pay for more costs. Because the willingness to accept to pay
measures if additional improvements added from the current level of safety or quality
of source.
From Figure 7, when the households became partially satisfied, their willingness to
pay reduced especially for the rural areas of which alternative water sources of both
improved and unimproved sources are available. It assumed that if they are not
satisfied they equally benefited from unimproved sources. Whereas those households
who are satisfied with the current improved source their willingness to pay is
enhanced. On the contrary with an increase in satisfaction or at very satisfied level the
households‟ economic factors seams dominant especially in urban areas so that their
willingness to pay decreased. In addition to that households may not be interested to
pay above what they expect to pay. According to this study not only consumers
satisfaction but also perceived quality of the source were factors determining
accepting to pay for improved services.
According to the following two figures 6 and 7 it was possible to draw priorities of the
people to full fill their desire among the two parameter i.e. quality and quantity based
on their willingness to pay. Therefore taking the normal situation and assume the
water supply source deliver safe or quality and enough quantity of water. At this point
it is observed that the households were more willing to accept to pay for quantity or
availability of water than quality of water.

CHAPTER FIVE
5 CONCLUSION AND RECOMMENDATION
5.1 Conclusion
The study reveals issues related with water supply and sanitation behaviors in the
study area. Indeed it will give a brief understanding about household water
consumption, perception of water quality of improved and unimproved sources,
perception vice actual laboratory quality results, level of water sources status such as
its functionality, measure of protection, and surrounding cleanness during the survey
and access of improved water supply points coverage‟s from urban and rural areas. In
addition to that it was tried to identify the determinants of households reluctant to use
improved water sources than unimproved sources. Therefore the study took 160
households to conduct the survey in which the respondents were beneficiaries of those
randomly selected 16 water points. The result of the study understands the following
findings:
The major responsible bodies for water collection were women and children besides
the work load of women doing the home activities even field works with men. It was
good extension observed that the use of plastic pot that is Jeri cans which reduces the
heavy load and contamination. Because women‟s travel long up and down slope and
far distances with heavy clay pot materials but it was better to replace by Jeri cans.
And dropping the water from the Jeri can reduces the direct contact in between the
storage and consuming material. Besides that the presence of alternative unimproved
sources of about 46% increases the chance of the people depend on these sources.
59
The per capita water consumption has a negative relationship with household size both
from urban and rural areas. Besides that queuing time negatively correlate with per
capita consumption in urban areas. There is a positive relationship between waiting
time, distance, adequacy and quality of water source for the consumption of
households from unimproved sources in rural areas. In contrast queuing time and
income were the main factors resulting households reluctance to collect water from
improved sources in the urban areas. This leads to vulnerability of the households to
water borne diseases. As a result of this it is better to reduce the queuing time by
installing additional water supply points. Because the time devoted for water
collection losses the possibility of spending on other productive activities.
To understand the people‟s perception on the quality of their water sources of both
improved and unimproved, it is evident that people have the capacity to identify the
quality of their water through test, odor and color. Furthermore test was the main
indicator of water quality in the study area in which 64% of the respondents measure
the quality of the source. As a result of this one scheme become out of use due to its
displeasing test. It was interesting that the result obtained from people‟s perception
lies with the actual laboratory results. On the contrary tap water was the only source
which satisfies the standards of water quality from the selected water sources but some
people dislike consuming from this source as compared with the nearby protected
sources. The main reason were chlorination and test less of the water than the spring
not transported though pipe and feel comfort while drinking and cool.
It was impossible to isolate the sanitation and hygiene practices from the water quality
perspective (water aid, 2009). Out of the total respondents about 79% of which
defecate on open field and from those having the physical latrines only 65.5% of those
currently use the latrine and out of which 28.9% of children did not use the toilet.
60
Functionality of the water source was also seen from the field which shows except one
scheme 43.75% of well functioning and 50% functioning with some breakages.
Although one scheme was included under well functioning it doesn‟t give the service
to the households due to its quality problem. The surrounding neatness has its own
contribution for the quality of water. Therefore 37% of improved sources were not
neat at all while other are neat and somewhat neat surroundings. Despite protecting
and cleaning the surrounding it is difficult to see neat surrounding. So that about half
of them were not protected at all while the rest 23% and 27% of sources were
somewhat protected and well protected respectively.
One of the MDGs aim was sustainable accessing to improved and quality drinking
water for the people who are without this resources. Although many efforts have been
applied to achieve this goal for the people it is still a problem to reach the target
objective. Among the many reasons such as quality of the scheme, dependency of the
people on unimproved sources, nonfunctioning of sources and others the focus given
for the term access by itself has misleading. As a result of that there were two ideas
while about access coverage for the district. One is standards based which took the
capacity of the scheme while the second was actual access coverage implies the
district has 50% and 27% access coverage respectively. Consequently this discrepancy
leads to stop the development endeavors after a while when the 100% recorded from
the standard based report which is recommended by the regional office.
The households have a better awareness about their source potential and the problem
as well. As a result many of the people were willing to pay for the improved sources.
But very limited sources about 31% currently pay for the source especially most are
for the salary of the guard. But there was still a need to create awareness why the
61
water use committees selected and up to what range they had the potential to do
activities alone.
Furthermore due to vast coverage of the area the district experts did not reach to the
site immediately when the schemes stop working. This forces the household to depend
on unimproved sources. To resolve such technical problems even though training was
given for the selected water use committees but they complain that they couldn‟t do
that because of the minor training was given without technical equipments. To sum up
with the households preference for pay for quantity of water was more important than
quality of water.
5.2 Recommendations
A given water scheme should supply only for the targeted groups rather than
creating competition between households with other more water consuming
activities such as schools feeding programs, nursery site, etc.
Giving attention for unimproved water sources may reduce the rural people
immediate consumption from polluted water so that advice to protect the schemes
from direct contact with animals, treatment measures taken and others because
people in reality still dependent on unimproved sources.
Taking the actual coverage of access to improved water sources will motivate
funding agencies to participate for development endeavors than taking the
exaggerated reports that brings half of the people without access to water after a
time.
A lot of awareness creation activities should be done on sanitation and hygiene
through extension workers not only for preparing latrines but use of the latrines
and hand washing practices.
62
Continuous follow up on already installed schemes give a better chance to sustain
schemes.
Strengthening institutional arrangements will increase the continuous inspection of
schemes health and functionality.
