Kuja which rises from Kiabonyoru hills in Nyamira County is the main river and has adequate water for the development of a mini hydro electric station. Other streams are mogonga, mogusii, Riana and Iyabe. There are also numerous springs and boreholes which are sources of clean water for both human and livestock.

Sanitation

Kisii County does not have good drainage system and most towns in the county have poor drainage. Waste management is not properly managed in the county because there are no designated sites for wastes. Most households have pit latrines in the county. Hence there is need to connect households to the sewer lines especially in major towns and establish dumping sites or start a waste recycling plant.
