The multibillion-shilling Mwache Dam in Kwale County is racing toward completion, with the contractor now indicating the project could be commissioned this year — ahead of schedule. The Ksh 25.6 billion mega-project is already 83 percent complete, marking significant progress on one of Kenya’s most critical water infrastructure investments.
However, a parliamentary watchdog has sounded the alarm over potential delays caused by inadequate funding for the water treatment plant and pipeline installation components of the project.
What the Dam Means for Coast Region
Once operational, Mwache Dam will be a game-changer for Kwale, Mombasa, and the wider coastal region. The dam is designed to supply over 180,000 cubic metres of water daily, addressing chronic water shortages that have plagued the Coast for decades.
For residents who have relied on erratic water supplies and expensive tanker deliveries, the dam promises a reliable, affordable alternative. The project also has potential for hydroelectric power generation, adding to Kenya’s renewable energy mix.
The Funding Challenge
Despite the impressive progress on the main dam wall and reservoir, the downstream infrastructure is underfunded. The water treatment facility — essential for making the water safe for domestic use — and the distribution pipelines that will carry water to homes and businesses still need significant capital injection.
Parliament’s Public Investments Committee has warned that without urgent budgetary allocation, the dam could end up as a multi-billion-shilling white elephant — full of water but unable to deliver it to the people who need it.
Looking Ahead
The government has expressed commitment to completing the project, citing it as a flagship initiative under its Big Four Agenda successor programs. With heavy rains currently pounding the region filling reservoirs across the country, there is added urgency to get the treatment and distribution systems ready before the dam reaches full capacity.
If the funding gaps are addressed in time, Mwache Dam could begin transforming lives in the Coast region before the end of the year — a rare bright spot in Kenya’s often-delayed infrastructure landscape.
