The government has announced that construction of the Mwache Main Dam in Fulugani, Kinango Sub-County, Kwale County, has reached 90 per cent completion, with reservoir impounding now targeted for October 2026.
Water and Sanitation Principal Secretary Julius Korir said the project remains on schedule and represents a major milestone in efforts to strengthen water security across the Coast region.
Korir made the announcement after inspecting the dam site, where he reviewed progress on the ongoing construction works and held consultations with engineers, contractors and project managers.
“The project remains on track for impounding by October 2026, marking a major milestone towards enhancing water security in the Coast region,” the PS said.
The Mwache Dam is one of the government’s flagship water infrastructure projects and is expected to play a central role in supplying reliable water to households, industries and public institutions in Kwale and Mombasa counties.
Once completed, the dam will have a storage capacity of up to 136 million cubic metres of fresh water and is designed to produce approximately 186,000 cubic metres of treated water per day.
According to the Ministry of Water and Sanitation, the project is expected to benefit more than 1.6 million residents in the two counties, helping address longstanding water shortages that have affected domestic consumers, businesses and key economic sectors such as tourism and manufacturing.

The inspection visit came hours after Water, Sanitation and Irrigation Principal Secretary Eric Mugaa also toured the project site. Mugaa described the dam as a flagship investment under the government’s Bottom-Up Economic Transformation Agenda (BETA), saying it would enhance water security, support economic growth, create jobs and strengthen climate resilience for communities along the Coast.
Mugaa noted that the 84-metre-high roller-compacted concrete gravity dam had risen to about 79 metres, with construction progressing steadily toward full completion.
The project team was directed to maintain the current pace of work and ensure that the remaining activities are completed within the agreed timelines and to the required technical standards.
Korir said the ministry would continue working closely with the project team and other stakeholders to guarantee timely delivery of the remaining works.
He added that the Mwache Dam is a transformative investment that will not only improve access to clean water but also support agriculture, industry and broader economic development in the Coast region.
The dam forms part of the government’s wider programme to expand water infrastructure, improve resilience to climate variability and support long-term social and economic development in underserved regions.
