Construction of the Semwa Dam in Mashonaland Central is progressing steadily, with engineers estimating the project is now between 32 and 42 percent complete. Authorities say phased commissioning is on track to bolster water security, irrigation and economic recovery across Rushinga and Mt Darwin districts. Designed to store around 260,000 megalitres of water, the dam will support approximately 12,000 hectares of irrigation while also facilitating potable water supply, fisheries and tourism activities.

Government officials and the Infrastructure Development Bank of Zimbabwe (IDBZ) confirm the project has regained momentum after early delays, and is now fully funded by the State. Completion is scheduled in phases through 2028. With a planned 72-metre dam wall, Semwa is positioned to become one of the region’s largest reservoirs, potentially converting dryland farming into viable commercial agriculture.

Local leaders expect significant socio-economic gains, including job creation during construction and expanded agribusiness once operational. Project planners say the dam will stabilise crop production, improve food security and catalyse small-scale industries around water access points, helping communities withstand recurring droughts.

Site reports show earthworks and cofferdam phases are well under way, paving the path for wall construction, spillway development and intake structures. IDBZ has listed Semwa among its flagship infrastructure programmes and is providing periodic updates on funding flows and procurement progress to maintain continuity and avoid previous stop-start setbacks.

Environmental assessments and community resettlement plans have been completed to address social impacts, with compensation processes ongoing. Observers emphasise that adherence to environmental safeguards, transparent procurement and consistent financing remain crucial to avoid cost escalations or delivery delays.

“When complete, Semwa Dam is expected to power agricultural development, improve access to clean water and open new opportunities for tourism and small-scale industry.” — Francis Dzenga, Assistant Resident Engineer.

Civil-society groups are calling for regular public oversight of budget utilisation, contractor performance and resettlement progress. Semwa’s advancement marks a critical step toward improved regional water security and rural economic growth, with stakeholders set to monitor quarterly milestones and safeguard commitments through to completion.
