REGULAR TARIFF ADJUSTMENT IN ATHI WATER SERVICES BOARD (AWSB) AREA
The Water Services Regulatory Board (WASREB), under the powers granted by section 72 (1) (b) and (2) of the Water Act, 2016, has approved
the regular tariff adjustment for the area served by Nairobi City Water and Sewerage Company (NCWSC).
NCWSC applied to the Water Services Regulatory Board (WASREB) for a review of water services tariffs for the period 2025/2026 to
2028/2029 in line with section 72 (1) (b) of the Act. Public consultation on the NCWSC application was carried out as per the requirements of section
139 of the Water Act, 2016.
Having considered the application, the written and oral submissions by all stakeholders and the current data, WASREB has determined that an
upward tariff review is justified for NCWSC to improve service delivery, operate sustainably and protect consumer interests by meeting the tariff
conditions attached to the tariff.
WASREB hereby gives a one-month notice from the date of this communication to all existing and potential customers of NCWSC that the
structure of approved tariffs for water services for the four financial years 2025/2026, 2026/2027, 2027/2028 and 2028/2029 shall be as follows:
