South Africa pilot uses stone, wood, and sand to filter river water for irrigation.
University of Cape Town researchers installed a filtration system in a South African town. The single river/community pilot uses stone, heat-treated wood, and sand to treat 36,000 litres of polluted Stiebeuel River water per day for community vegetable plots. This is an early-stage pilot, and its long-term effectiveness and maintenance have not yet been independently assessed.
Why it matters
This pilot demonstrates a viable method for locally purifying agricultural water with simple, renewable materials in response to river pollution that threatens food security.
