Abstract
Agaro Town has been experiencing the problem of potable water supply in adequate quality even
if the modern water supply system was installed since in 1961 and expanded its service by
drilling a number of boreholes, it is common to see red water color in different interval of
months .Still a number of people do not have access adequate amount of potable water and also
they are not used for all home consumption. This research has focused on Water quality
problems in town and its impact different bodies.
Laboratory analysis characterizing and evaluating its quality by comparing with WHO and
Ethiopian Standards is used in this research for identifying water quality problems in the town.
By preparing Questionnaires with the aim of recognizing impact of water quality problems , for
different people that cannot used distributed water for all home consumptions like merchant of
the town that can partake coffee and tea, and people that can follow Muslim religion they
cannot used for preparation of soup in the month of Ramadan. Economical loss by requiring
another source of water is described in this body of this study.
TWATER CAD software is used in water distribution system to analyze pressure and velocity
and Pressure measurement was taken in different location of distribution system for the purpose
of calibration. The parameters like Iron, Electrical conductivity, Total coli form, Turbidity,
Dissolved oxygen and E. coli are not within the maximum permissible limit prescribed by WHO
and Ethiopian drinking water quality standard.
The max and min pressure by WATER CAD is at 7 and 10 junction respectively and max
and min velocity is at 5 and 21 links respectively, whereas by Gagged pressure at sample
location point is 3 junction low pressure observed . The total simulation accuracy of pressure in
the network systems as assessed by statistical methods, R
=0.899
Generally it can be concluded that the source of water supply contain high level of iron, it affects
color of coffee, tea and soup this results affect high cost loss in merchant of the town that
participate on preparation of coffee and tea , the people that follow Muslim region because of
soup is prepared during the month of Ramadan, high level of iron contain high corrosive problem
it affect pipes and pumps in the borehole . The other is as they not used pre and post chlorination
total coli form and ecoli is show above permissible limit because this water born and water
related disease is the first top ten diseasesshown in the town.Aeration, chlorination and house
hold water treatment like boiling is the most recommended for removal of these contaminants in
the town water supply system. KEY WORD:-water quality parameters, physical, chemicaland
