Feasibility study for hydropower plants at chania river outfall and thika dam, and design and supervision of the construction of hydropower power generation station at chania river outfall.

Athi Water Services Board intends to utilize the existing hydropower potential in its existing water facilities and generate electricity either for integration into the grid or direct usage in order to meet the increasing demand for power in Kenya.This project will exploit the residual head at the Chania outfall estimated to be about 50 meters and with an average flow of about 2.5 m³/sec in a run-of-river power generation scheme.Chania outfall is the point at which water from Thika dam together with that abstracted from Kiama and Kimakia Rivers is transmitted to Mwagu intake through a series of tunnels. Mwagu Intake the water is again transmistted through a tunnel and a pipeline to Ng’ethu water production plant for treatment and later transmission to Nairobi City for consumption. The scope of works will be in two phases as follows:a) Phase 1: Feasibility study for Hydropower Plants at Chania Outfall (3MW) and Thika Dam (1.2MW), and Preparation of Design and Bidding Document for Chania plant, b) Phase 2: Supervision and Coordination of Hydroelectric Power Generation Station at Chania Outfall.
