What Nyeri Water And Sanitation Company Limited (nyewasco) does

Nyeri Water and Sanitation Company Limited (NYEWASCO) is a county government-owned water and sanitation utility incorporated on September 23, 1997, operating under the regulation of the Water Services Regulatory Board (WASREB) and oversight of the Nyeri County Government. The company provides treated water supply, sewerage, and sanitation services across Nyeri Central Sub-County, Kenya, serving over 100,000 residents at 99% water coverage and 100% drinking water quality compliance. Core operations are anchored on the Chania River water source with a treatment capacity of 27,000 cubic meters per day (upgraded from 6,000 cc in 2004 with GTZ support), supporting facilities including Kangemi Treatment Works, Kamakwa Treatment Plant, Gatei Sewerage Treatment Plant, and multiple pumping stations.

The company's technology stack centers on smart water management — smart meters, acoustic leak detectors, GIS integration, real-time monitoring tools, and system automation for billing and customer service — which has driven non-revenue water down to 16.79% versus a 42% national average. NYEWASCO holds ISO/IEC 17025:2017 laboratory accreditation (serving as a NEMA reference lab) and operates an all-services mobile application launched in 2022 alongside 24-hour customer service and toll-free support channels. Supporting products include automated water kiosks in low-income areas (Witemere) operating on mobile money tokens, and an alternative services line for areas outside the main piped network.

The business model is fundamentally a regulated utility: revenue is generated through consumption-based water tariffs and sewer charges (sewer billed at 75% of water volume consumed), with a pro-poor cross-subsidy in which higher-consumption customers subsidize lower-income users — production cost is Ksh 66.08/unit but the pro-poor tariff charges Ksh 47/unit (a Ksh 19.08 per-unit subsidy covering 72% of consumers who consume up to 6 units monthly). Customer segments are residential (primary, 100,000+ residents), low-income area residents served via subsidized tariffs and kiosks, and commercial/industrial customers on business-account minimums. NYEWASCO has held the #1 WASREB ranking among 81 Kenyan water utilities for 18+ consecutive years and was named Best in Eastern and Southern Africa by ESAWAS in 2024.
