Water treatment plant is collectively the industrial scale process that makes water more potable or useful by the
use of some processes according to the tests and experiments carried out on the water. This project involves the use of
surface water. Surface water could be regarded as all inland water permanently or intermittently occurring on the earth
surface. The two sources of surface water used are ‘Elemi’ and ‘Ureje’ River. The objectives of this project is to find
out the quality of water based on BOD, COD, DO, pH and other water quality parameters and to provide information
for engineers to execute the project. The process involved in making these water sample potable are; pretreatment,
coagulation, flocculation, sedimentation, filtration and disinfection. In comparing the quality of water from the Elemi
River and Ureje River, it can be concluded that Elemi River is better to use for domestic purposes than Ureje River
