The Board’s area of jurisdiction spreads over the counties covering the original
8 larger districts of Turkana, West Pokot, Baringo, Keiyo, Koibatek, Nyandarua,
Nakuru and Narok. According to the 2009 Census, the Board’s area has population
estimated at 6 million people.
The Board commenced operations in 2004,
initially by taking over all operations previously managed by the Ministry of
Water & Irrigation as well as those that were being managed by the National
Water Conservation & Pipeline Corporation. Since then the Board has
appointed 11 Water Services Providers (WSPs) to manage water service provision
on agency basis. This policy decision has enabled the Board to concentrate on
making strategic investment decisions as well as regulate the WSPs.
