I.  INTRODUCTION TO WATER SUPPLY

Water supply system, infrastructure for the collection, transmission, treatment,

storage, and distribution of water  for homes, commercial establishments, industry,

and irrigation, as well as for such public needs as firefighting and street flushing of 

all municipal services, provision of potable water is perhaps the most vital. People

depend on water for drinking, cooking, washing, carrying away wastes, and other 

domestic needs. Water supply systems must also meet requirements for public,

commercial, and industrial activities. In all cases, the water must fulfill both quality

and quantity requirements. Water was an important factor in the location of the

earliest settled communities, and the evolution of public water supply systems is tied

directly to the growth of cities. In the development of water resources beyond their 

natural condition in rivers, lakes, and springs, the digging of shallow wells was

probably the earliest innovation. As the need for water increased and tools were

developed, wells were made deeper.

In addition to quantity of supply, water quality is also of concern. Water treatment

is the alteration of a water source in order to achieve a quality that meets specified

goals. Treatment methods included sand filtration as well as the use of  chlorine for 

disinfection. The virtual elimination of diseases such as cholera and typhoid in

developed countries proved the success of this watertreatment technology. In

developing countries, waterborne disease is still the principal water quality concern.

II.  AREA INSPECTED

Pallocan West !ural Waterworks and "anitation Association was the area

selected by the inspectors. The area was referred by the #atangas $ity Water 

%istrict $W%' Production %epartment (anager, )ngr. #ernardo $. *ornilla for this

area is the nearest area not supplied by the #$W%. )ngr. +ose !oberto (.

(aranan, the )ngineering %epartment (anager also contributed information about

#$W% where the inspectors find it helpful to compare and make inqueries with the

findings at the selected area, Pallocan West !ural Waterworks and "anitation

 Associations distribution system.

i. Location

Pallocan West !ural Waterworks and "anitation Association is around

Pallocan West, #atangas $ity, -ust a few steps away from $alumpang #ridge.

There were four &' pumping stations handled by the Waterworks. The first

pumping station is behind the office of Waterworks, and the other stations are

at "antolan, "itio Ilaya and "itio "ilangan.

ii. History

%istribution system at Pallocan West !ural Waterworks and "anitation

 Association was operating since /000. 1ther history information were

unknown since the first batch of waterworks has been placed.

III.  SOURCE

Water resources are sources of water  that are useful or potentially useful. 2ses

of water include agricultural, industrial, household, recreational and

environmentalactivities. The ma-ority of human uses require fresh water . The

sources of water is either be from surface of water, rainwater or groundwater 

The source used by the Pallocan West !ural Waterworks and "anitation

 Association is groundwater well. As previously said, there were four &' stations

distributing around Pallocan West, all of these were groundwater well source.

The station was protected by screen wires and the water storage tank was

elevated. The waterwell in the station was 3 meter deep connected to 4 inches main

pipe.

IV.  DISTRIBUTION SYSTEM

Pallocan West !ural Waterworks and "anitation Association distributes water to

two hundred fifty &435' households through four &' pumping stations6 two elevated

tanks and two pressuri7ed tanks.

The pump gives 3 horsepower to supply every household.

i.  Sizin an! Mat"ria#

The pipe from source to water tank is 4 inches diameter made of 

galvani7ed iron, while main pipe line to branches is 8 inches made of 

Polyvinyl chloride &P9$' pipe and the branches are 4 inches made of 

Polyethylene &P)' pipe and branches to households are made of P) pipe and

varies on their si7es.

The si7ing of main line to households depends on the building structure to

be supplied. :or a single family house, the pipe si7e used is ; inchesdiameter, for a small residential or commercial building, < inches diameter of 

pipe is used and for a large residential or commercial building they require /

inch pipe diameter.

V.  TREATMENT

The water being supplied passed through microbiological test &Total $oliform,

:ecal $oliform and *eterotrophic Plate $ount' which refers to Philippine =ational

Wastewater, 4/st  )dition, AP*A, Washington, %$. &"ee laboratory result,

documentary photos below'

 Apparently, the water distributor doesnt have any treatment used in water 

because the people in the area do not want any disinfectant like chlorine to be

in-ected in their water. The reasons why they do not want any disinfectant were

unknown, but there were hearsay prevailing that chlorination causes illness or worst,

cancer. They also think of why all the fish die when chlorine is added in aquarium, so

then why are they drinking and showering in this chemical that kills another 

organism in a matter of hours@

#esides, the waterworks are flushing water mains every 8 months to ensure that

there were no sediments built up inside the pipes. The main source of water is being

tested every months to guarantee its safety.

VI.  MODE O& PAYMENT

The cost of water for every first /5 cubic meters in #$W% is Php 453.55, while in

Pallocan West Waterworks gives it only Php /55.55, which is a very big difference

thats why they do not tend to assign #$W% handle their water.

)very household has water meter but the station doesnt have, unlike at #$W%.

The advantage of having a water meter at the station is that the water being supplied

is always monitored, of how much water has been supplied or also if there were

leaks.

VII.  PROBLEMS AND OBSERVATIONS

In this area, there are several problems encountered and some solutions made.

*ere are some6

PROBLEM SOLUTION

contaminated water flushing

leaks repairs

dripping water

Though the water quality from source has passed, the quality coming out of the

households faucets were unsure. The water from the households is being

contaminated due to pipes damage where some constituent comes in. %ripping of 

water is also a huge problem but they do not have a solution for this. Beaks andflushing can cause dripping of water.

1ther stuff has been observed like the leak from the main pipe and the grubby

spot of the pumping station. As far as concerned, there was no number of people

become ill due to the water quality. The water quality is safe for drinking as seen in

the result of laboratory tests but some of the residents still buy drinking water for 

safer use.

VIII.  RECOMMENDATION

In the cases above &see table' as well as the observations, here are some

recommendations6

• :or having a contaminated water, &since the contamination comes from

the pipes damge' a better way to make sure that the water is safe is to

install a water purification system in every house, such as a distilled water through water distiller or a reverse osmosis system, which both systems

use multistage purification. 1ther can -ust boil water for relative purposes,

and some may install a filter in every faucet or hose in their house.

• Protection of the pumping station must be closed room and not screen

wires for it can still be easy to access for deep well in-ection and to some

animals. In addition, the pumping station must always be clean.

• The pump requires higher than 3 horsepower to supply a greater pressure

and give a streaming of water.

• Pipe si7e may vary after changing the power of pump.

• !egular monitoring of pipes is necessary to avoid leaks and other 

damages.

• %ig well deeper than 5 ft to acquire safer water. Bess than 5 ft well is

prone to contamination.

• !egular test of water to authori7ed laboratory is required to ensure that

the water being supplied is still safe.

• 1pening a feedback from consumers is suggested to secure their needs.
