WATER SUPPLY AND QUALITY CONTROL IN KISUMU CITY The city is supplied with water from KIWASCO water treatment plant located in Dunga. The plant obtains its water from L. Victoria. Water treatment process Intake Water is pumped into the plant from the lake. Sodium carbonate is added to obtain a p H of 7 for proper coagulation. Flocculation The water moves at a slow speed for coagulation of impurities and suspended particles into larger particles that can settle down at the sedimentation tank. Samples are taken for jar test at this stage. Sedimentation Water enters slowly for proper sedimentation. The floc blanket settles down. More tests on p H, color and turbidity are done. The suspended solids should be zero. Filtration The tank is trapezium-shaped. Stones are arranged from fine sand at the top to pebbles at the bottom. Pipes are placed strategically at the bottom to take in filtered water. Backwashing Water is passed through the filters from the bottom to the top. This is done to clean the filters Chlorination Water is pumped into a tank where chlorine is added to remove oduor, color and kill pathogens. The recommended residual chlorine is 0.2-0.3 mg\l. The water is then pumped to the city.

Hello Okoth!
It's your SJ mentor.
Hope things are fine with you.
Thank you for introducing the process of water supply to the city.
In Korea, tap water is supplied through a similar process.
Even if residual chlorine is removed, drinking does not cause any problems.
However, saving and managing water sources is very important because only about 3% of the total water resources are available to humans.
It would be nice to introduce not only the water purification process but also what efforts are being made to promote water circulation eco-friendly.
Green cheers!
Sincerely,
SJ mentor.

Hello Okoth,
this is your mentor WooJoo.
I hope you are doing well.
Thank you for sharing your report regarding water supply and its quality control in your city.
In Seoul, the capital city of South Korea, is having Han River and Paldang dam as water supply for the city's tap water, called Arisu.
Maintaining water quality high is very important since we use it every day, and even some people drink it.
It would be helpful if you can write more about details of the quality of water running the city, and its surrounding ecosystem.
Okoth, your reports are falling short of length, and you are missing the references too.
Please keep this in mind, and try to write longer next time.
Regards,
WooJoo
