The push to secure Nairobi’s future water supply gathered fresh momentum on Thursday, February 26, 2026, as Athi Water Works Development Agency convened a high-level stakeholders’ meeting in Nairobi to review progress on the proposed Maragua IV Dam Water Supply Project.
The meeting brought together key players from government, technical teams, and local communities in a collaborative forum aimed at shaping the next phase of the project. At the heart of the discussions was the transition into the detailed design stage—an important step that signals steady progress toward implementation.
Once completed, the Maragua IV Dam is expected to significantly ease water shortages in the Nairobi Metropolitan region. With an estimated storage capacity of 120 billion litres, the dam will supply an additional 140 million litres of water daily to Nairobi and surrounding areas such as Thika, Juja Farm, Konza City, Syokimau, Ngong, and Mlolongo. An additional 20 million litres per day will be directed to communities in Murang’a South, boosting water access in the region.
During the engagement, AWWDA officials outlined key milestones already achieved, including the completion of preliminary hydrological assessments for the South Mathioya and Maragua rivers, materials investigations, and early pipeline route analysis. These studies, stakeholders were told, form the backbone of the detailed design process and will guide the project’s eventual construction.
Beyond the technical updates, the forum also highlighted the broader impact of the dam. Participants were briefed on its potential to support urban growth, drive socio-economic development, and enhance long-term water resilience in both Murang’a County and the greater Nairobi area.
The session further provided a platform for open dialogue, with stakeholders raising concerns, offering recommendations, and aligning on the path forward. The agency emphasized that such engagements are central to ensuring transparency, inclusivity, and sustainability in delivering large-scale infrastructure.
As Nairobi’s population continues to grow and demand for water rises, the Maragua IV Dam project is shaping up as a critical piece in securing the region’s water future—one that planners say must be resilient, sustainable, and built with the input of all stakeholders involved.
