South Africa is taking a major step toward water sustainability by developing its first Water Efficiency Labelling Scheme (WELS). This national initiative will help reduce water consumption, lower energy demand, and advance the country’s climate goals.

The scheme will introduce standardized labels for products such as taps, toilets and showerheads to help people and businesses make smarter choices that save water and lower costs. It is being led by the Department of Water and Sanitation (DWS) in partnership with the South African National Energy Development Institute (SANEDI), Water Research Commission (WRC), Department of Trade, Industry and Competition (dtic) with technical support from CLASP.

CLASP experts provided timely research that helped shape the scheme. Their in-depth analysis found that adopting water-efficient products—especially for faucets and showerheads—could help South Africa save over 1 trillion litres of water, reduce energy use by 18 terawatt-hours, and avoid 16 million tonnes of carbon dioxide emissions each year.

“This scheme lays the groundwork for widespread adoption of water-efficient technologies in homes and commercial buildings. It supports smarter consumer decisions and accelerates progress toward climate resilience,” Angellah Wekongo, Senior Associate at CLASP.

The WELS initiative comes at a critical time, as South Africa faces growing water stress and a projected 17% shortfall by 2030. CLASP’s research shows that appliance energy efficiency is one of the most cost-effective means of reducing emissions, improving resilience for climate-vulnerable communities, and supporting sustainable development.

“We work with policymakers around the world to provide technical expertise and cutting-edge research on how to achieve international best practice in appliance efficiency. Water efficiency is a strategic priority, and our partnerships in South Africa are key to strengthening climate action and advancing sustainability across Africa,” Anne Muhonja Songole, CLASP’s Africa Climate Manager.
