Elsewhere, this comes months after the Water Services Regulatory Board (WASREB) announced plans to review water tariffs and licensing arrangements in three counties.
In a notice on Tuesday, March 31, the agency confirmed that it had received applications for water service retail licences and tariff adjustments from four Water Service Providers (WSPs).
The WSPs were Kisumu Water & Sanitation Company Limited (KIWASCO), Kirinyaga County Water & Sanitation PLC (KICOWASCO), Rukanga Makutano Water & Sanitation PLC (RUMAWASCO), and Takaba Water and Sewerage Company (TAWASCO).
According to the regulator, the proposed tariff adjustments were aimed at enabling full cost recovery, supporting critical infrastructure investments, and ensuring the long-term sustainability of water services.
According to WASREB, the review process covered parts of Kisumu County, Kirinyaga County, and Mandera County.
The agency noted that the review process would involve public participation in the affected areas, giving locals an opportunity to give their views on the proposed changes.
The regulator had scheduled a series of hybrid public consultation meetings, both physical and virtual, to facilitate this engagement.
"These meetings will provide stakeholders an opportunity to express their views on licensing, service delivery, tariff adjustments and potential service improvements," the notice read in part.
