The Water Services Regulatory Board (WASREB) has approved new water tariff structures for several Water Service Providers (WSPs), with the changes covering the 2026/2027 to 2028/2029 financial years.
In a gazette notice dated September 11, the Kiambu Water and Sewerage Company Limited (KIAWASCO) will charge between Ksh91 and Ksh160 per cubic metre for domestic water, depending on consumption.
For water kiosks, KIAWASCO will charge Ksh70 per cubic meter, with public resale capped at Ksh5 per 20-liter jerrycan. KIAWASCO’s regulated kiosk resale price will range from Ksh2 to Ksh3 per 20-litre jerrycan.
“Kiambu Water and Sewerage Company Limited (KIAWASCO) has received approval for an upward review of water service tariffs for the 2026/2027 to 2028/2029 period. The company had applied for the tariff review, citing the need to improve service delivery and ensure sustainable operations.
After considering the application, views submitted by stakeholders during the public consultation and current data, the regulator determined that an increase in tariffs was justified,” read part of the gazette notice.
