SuDS for managing surface water in Diepsloot informal settlement, Johannesburg, South Africa

摘要: Sustainable drainage systems (SuDS) imitate natural water management processes in catchments that have been degraded due to urbanisation. The aim is reduce the quantity of stormwater runoff and improve quality. Management rainwater informal settlement Diepsloot Johannesburg compounded by domestic wastewater discharged into lanes. These lanes fall outside mandate City Johannesburg’s system; hence residents need rely on their own initiatives address surface-water problems. This preliminary study investigated introduction SuDS enhance existing interventions, as a low-cost flexible approach. Using action research methods, small-scale interventions were designed, constructed refined researchers at two sites close Jukskei River. While primary intention was standing public areas, quality testing indicates reduced some pollutants. Nitrate phosphate concentrations slightly lowered through permeable channels soakaways, while these had moderate effect chemical oxygen demand. involvement markedly different, reflecting divergent priorities social dynamics. Spontaneous continuation system one successful knowledge skills exchange. limited duration with only sets tests; therefore, longer term monitoring strongly advised be able give more robust assessment this type intervention.
