Desalination plant increases drinking water production
Claudia ReiterWindhoek
The Erongo Desalination Plant (EDP) recorded another production milestone in 2025, producing a total of 17.59 million cubic metres of drinking water for the Erongo Region — a 14% increase compared to the previous year.
The increased output underscores the plant’s growing role in supplying coastal towns, mining operations and industry, while also strengthening national water security. The facility currently has the capacity to supply up to 22.5 million cubic metres of water annually and is designed for a long-term maximum capacity of 45 million cubic metres to meet rising demand.
A major highlight in 2025 was a new daily production record of 63,381 cubic metres, achieved on 17 June. The plant also marked 15 years of operation without a single lost-time injury, a significant safety milestone.
Sustainability remains a key focus. Since 2025, the plant has been partially powered by solar energy, helping to reduce operating costs and carbon emissions. These savings were passed on to consumers, resulting in a 2% reduction in water tariffs within a year.Located near Swakopmund, the desalination plant continues to serve as a critical pillar of Namibia’s water security, including long-term support for the central area around Windhoek, which increasingly depends on reliable alternative water sources.
