TANO RIVER

The Tano is the westernmost river in Ghana with its source near Techiman and terminates in Aby Lagoon at the south east corner of the Ivory Coast. The river flows in long stretches of gentle slope and a few reaches of rapids. The notable rapids are located downstream of Ausaso near Sedukrom and upstream of Tanoso. Upstream of Asuaso, the river has a gentle slope upto Sefwi Wiawso and further upstream it flows through a few swamps. In the initial reaches close to the source it has a very steep slope. 

UPPER TANO WITH MINI HYDRO SCHEMES

Upper reaches were omitted in previous developments. SECSD planning for the upper reach proposes minihydro projects upto 5000kW capacity suitable for implementation by local companies or rural communities. A total of nine such schemes were identified with total capacity of about 50MW.

LOWER TANO WITH MODIFIED PLANNING

The lower reach was originally planned with large dams for navigation with submergence. SECSD redesigned  the lower reach to avoid excessive submergence. The schemes in the new design are such that same equivalent amount of power of 150MW is obtained as per the original planning.
