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).

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.
