The dam is located in Baringo County, Koibatek District and has a capacity of 15 million cubic meters or 15 billion litres. Chemususu Dam discharges 35,000 cubic metres or 35 million litres of water per day. It was designed to serve at least 50% of Baringo County population which includes towns and various institutions within the County.


Soin-Koru Dam


The Soin-Koru Dam Development project is proposed to be located on the Nyando River in the vicinity of Muhoroni in the Western part of Kenya. It shall be 60km from Kisumu City and 5km upstream of Muhoroni town. The Dam will be located in Kisumu and Kericho counties.


Siyoi - Muruny Dam

















The proposed Muruny Dam is located near Kapsait Primary School at Murkokoi Center which is approximately 43km from Kapenguria Town. The site location is covered on SK Map 75/4 Cherangany at GPS coordinates 36 N 0761064 and UTM 0129350, elevation 2690 masl at the riverbed. The project area lies within the Rift Valley Drainage Basin. River Muruny emanates from Cherangany Hills and flows in a North Eastern direction before finally draining into Lake Turkana.


Kiserian Dam









Kiserian dam is located along Kiserian River about 2kms from Kiserian Township and will supply water to Kiserian, Ongata Rongai and parts of Ngong’ townships. The present (2010) total population of the area is about 124,000 people with a water demand of 8,450m3   per day. The 18m high dam will store 1.22Mm3 of water and supply 15,700m3  per day of water to the townships which will meet the future (2020) water demand.


Maruba Dam

















In June 2010, NWCPC finalized rehabilitation of Maruba dam by raising the height of the embankment wall and spillway by 6 m. This increased the dam’s storage capacity from 0.60 Million m3 to 2.45 Million m3.  Increase in storage volume has ensured increase in water supply to Machakos Town and its environs from 2,050 m3/day to 8,700m3/day.
