The Mwache Multipurpose Dam in Kwale County is nearing completion, with construction now 90 percent finished. Once operational, the dam will significantly improve water availability in Mombasa and Kwale counties, supplying approximately 186 million litres of treated water daily to over 1.6 million residents.
Standing at about 79 metres tall, the roller-compacted concrete gravity dam is expected to reach its full height of 84 metres soon. The government aims to begin impounding the reservoir by October 2026, marking a critical milestone in addressing the persistent water shortages experienced in Kenya's Coast region.
Strategic Importance and Benefits
- The dam will have a storage capacity of 136 million cubic metres (136 billion litres), bolstering water security in the region.
- It supports the government's Bottom-Up Economic Transformation Agenda (BETA) by fostering economic growth, job creation, and climate resilience.
- The increased water supply will relieve pressure on existing sources, benefiting households, industries, and institutions across Mombasa and Kwale.
Government Oversight and Commitment
Water and Sanitation Cabinet Secretary Eric Muga, alongside Principal Secretary Julius Korir and Water Secretary Eng. Samuel Alima, recently inspected the site in Kinango Sub-County to review progress. Muga emphasized the project's flagship status in enhancing water security and urged the project team to maintain momentum and adhere to high standards and timelines.
Korir reaffirmed the Ministry’s dedication to collaborating with contractors and stakeholders to ensure timely and quality completion of the dam.
Addressing Long-Standing Water Challenges
The Mwache Dam is poised to transform water supply dynamics in the rapidly growing Coast region, which currently faces a daily water deficit of 327,000 cubic metres. By increasing reliable water availability, the project will support socio-economic development and improve living standards for communities in Mombasa and Kwale counties.
