Our Services

Reliability

Continuous and dependable water flow at customer taps, minimising downtime. In urban areas, water is accessible within 30 metres; within 1 km in rural areas.

Accessibility

Universal access across our service area — physical, economic, non-discriminatory and informational access. Tariffs are set to match the local economy and national benchmarks.

Quality

All water supplied meets Kenya Bureau of Standards health and aesthetic standards — safe, clean, clear and pleasant in taste and odour.

Treated Water Supply

OLWASCO abstracts water from its 12 operational boreholes and from the Malewa River, treats it at our water treatment plant to meet Kenya Bureau of Standards quality, and distributes it through our pipe network. Water quality compliance has improved from 32% to 62%, with a target of 100% by 2030.

We supply water to 4,508 active connections and are expanding towards a target of 8,780 connections by 2030. Daily supply hours are currently 19 hours, targeting 22 hours by 2030.

• ✅ Domestic household connections
• ✅ Commercial premises connections
• ✅ Institutional connections (schools, hospitals)
• ✅ Government connections
• ✅ Public water kiosks in low-income areas

New Water Connections

OLWASCO is actively connecting new customers as part of our target to increase connections from 4,508 to 8,780 by 2030. Applications for new connections are processed by our Commercial Services Department.

We serve all five wards of Ol'Kalou Constituency: Ol'Kalou, Kaimbaga, Rurii, Milangine and Kanjuiri Ridges. A dedicated pro-poor connection programme is expanding access in Low-Income Areas (LIA) — currently at 11%, targeting 22% by 2030.

• ✅ Residential connections
• ✅ Commercial and business connections
• ✅ Institutional and government connections
• ✅ Low-Income Area (LIA) subsidised connections
• ✅ Meter installation and activation

Pipe Maintenance & NRW Reduction

Non-Revenue Water (NRW) — water produced but not billed — stands at 35%. Our Strategic Plan targets reducing this to 28% by 2030 through active leakage control, pressure management, network rehabilitation and enforcement against illegal connections.

Emergency response teams are available 24/7 for burst pipes, major leaks and supply failures. We have replaced 52 valves and installed 5 bulk meters for boreholes and 2 for District Metered Areas (DMAs).

• ✅ 24/7 emergency burst pipe response
• ✅ Active leak detection surveys
• ✅ Pressure zone management
• ✅ District Metered Area (DMA) monitoring
• ✅ Illegal connection enforcement
• ✅ Asset management and network rehabilitation

Sanitation & Sewerage Services

Sanitation coverage currently stands at 75%, targeting 85% by 2030. Sewerage coverage is at 1.5%, with a target of 5%. OLWASCO completed Phase 1 of the sewerage system under the Kenya Towns Sustainable Water and Sanitation Services Project (KTSWSSP) funded by AfDB.

We adopt ecological sanitation solutions and technologies, build and maintain public sanitation facilities, and sensitise communities on proper sanitation and hygiene. Wastewater standards compliance is at 92%, targeting 100% by 2030.

• ✅ Sewerage line connections
• ✅ Public sanitation facilities and ablution blocks
• ✅ Ecological sanitation technologies
• ✅ Wastewater treatment and management
• ✅ Community sanitation sensitisation

Borehole & Spring Development

OLWASCO operates 12 boreholes — increased from the original 1 in 1973 to 12 today. New borehole drilling is planned under the Strategic Plan 2026–2030 to increase water production capacity and reduce dependency on the Malewa River, which faces challenges from illegal abstractions by upstream farmers.

We work in partnership with CRVWWDA, WSTF and the County Government to fund and implement new water source development including borehole drilling, spring protection and solar pump installation.

• ✅ 12 operational boreholes currently
• ✅ Hydrological and hydrogeological surveys
• ✅ New borehole drilling and casing
• ✅ Solar pump installation and maintenance
• ✅ Spring protection and capping
• ✅ Water production capacity expansion
