DO YOU KNOW THAT…

The United States has one of the safest water supplies in the world.

More than 3.4 million people die each year from water, sanitation, and

hygiene-related causes. Nearly all deaths, 99 percent, occur in the

developing world.

In 2011, 768 million people were still without access to improved sources

of drinking water while 2.5 billion people did not use improved sanitation.

Globally, diarrhea is the leading cause of illness and death, and 88 per

cent of diarrheal deaths are due to a lack of access to sanitation facilities,

together with inadequate availability of water for hygiene and unsafe

drinking water.



WHAT IS THE PROBLEM?

Presently, COWD has been conducting periodic water qualitymonitoring with the parameters of pH level, turbidity, and the

residual chlorine of the water supplied by RVWCI before it reach

and mix with COWD water supply. Water samples from the

RVWCI pipeline are manually collected by COWD personnel

and analyzed in the laboratory for the purpose to characterizeand identify changes of trends in water quality before it reach

consumers and able to respond to emerging water quality

problems.



The researchers sought to answer the

following:How can we improve the present water quality

monitoring system with less human

intervention?



OBJECTIVES OF THE STUDY :

1. To design a remote monitoring system for water quality

parameters namely: dissolved oxygen and conductivity.

2. To develop a database that will received and store data.

3. To make a graphical user interface (GUI) that will display

and store the monitored parameters of quality of water

from the remote area.

This study aims to design and implement a monitoring

system to monitor specific parameters of water:



Significance of the Study :

•

To the consumers, this project would help them know the quality ofwater that they are drinking because the readings of the monitored

parameters of water will be easily viewed online by visiting the website

that will be provided.

• To the COWD members, this project would help them conserve their

strengths and their time as well, because instead of going to the site

where the water source is located to get water samples and go back to

their laboratory to test those samples, they can easily remotely

monitor the water quality using telemetry.



WATER QUALITY :

- refers to the chemical, physical and biological characteristics of

water.

Physical parameters are: Temperature, taste and odor, turbidity,

true color and total dissolved solids which can be link to

conductivity.

Chemical parameters are: hardness, pH and dissolved oxygen.

It is a measure of the condition of water relative to the

requirements of one or more biotic species and or to any human

need or purpose.



WATER QUALITY INDICATORS



SENSORS USED:

Conductivity. in water is affected by the presence of inorganic

dissolved solids such as chloride, nitrate, sulfate, andphosphate anions (ions that carry a negative charge) or

sodium, magnesium, calcium, iron, and aluminum cations

(ions that carry a positive charge). Organic compounds like

oil, phenol, alcohol, and sugar DO NOT conduct electrical

current very well and therefore have a LOW conductivity whenin water. Conductivity is also affected by

Temperature: the warmer the water, the higher the conductivity.

Distilled water has conductivity in the range of 0.4 to 3 mS



CONDUCTIVITY SENSOR



Dissolved oxygen. analysis measures the amount of

gaseous oxygen (O2) dissolved in an aqueous solution.Oxygen gets into water by diffusion from the surrounding air,

by aeration (rapid movement), and as a waste product of

photosynthesis.

Dissolved oxygen criteria for drinking water which exist in

adjacent jurisdictions include: 5 mg/L minimum-same as foraquatic life , >8.0->9.5 mg/L-same as for aquatic life
