Water Supply

The Water Services Boards were mandated to supply water but not directly. Supply of water was to be done through a contractual agreement between the Boards and their agents called Water Service Providers. However for the case of the Coast Water Services Board, the bulk water supply is handled by the Board which then sells the commodity to the Water Service providers. This was inevitable especially for the transboundary water supply system which include the Mzima pipeline, the Marere pipeline, the Baricho pipeline and Tiwi boreholes.  Our  area of jurisdiction coincides with the administrative boundaries of the Coast Region covering six counties namely :

  • Mombasa County
  • Kilifi County
  • Kwale County
  • Taita-Taveta County
  • Lamu County
  • Tana River County
