showing the position of Densu Basin and its hydrological map.
Densu is considered to be one of the most important rivers in the country with
respect to its social and economic importance as a water supply source to
communities along its route (WARM, 1998, WRC, 2000). In addition, it is also
the main source of the drinking water supply for the western part of the capital
city of Accra because it flows into the Weija Reservoir, which is a major source
of potable water for south western Accra. The cost of treating water from the
Densu River is about ten times that from the Volta River at Kpong (which is well
managed by the Volta River Authority because of the Akosombo hydroelectric
project scheme on the River Volta), but because it is supplied by gravity it
makes it more economical than the water from the Volta which must be pumped
to Accra.
