ABSTRACT
Water Sensitive Urban Design (WSUD) presents a process towards the objective of a water-sensitive city. An integrated approach requires community acceptance to implement WSUD at household level. An exploratory comparative survey was conducted amongst 250 households across Cape Town and Pretoria, South Africa, to determine actual uptake of rainwater harvesting, greywater recycling systems and permeable paving, factors affecting uptake, and the perceived effectiveness of assistance to implement WSUD relative to other water demand-side management instruments. Actual uptake of rainwater harvesting and greywater reuse is noticeable amongst water-saving middle-to-high income home owners. Although loglinear analyses suggest that Cape Town’s recent drought is unlikely to contribute towards more established levels of uptake, assistance to implement WSUD is nevertheless perceived as the second most effective instrument. Three directions for more systematic research are proposed to better inform the practical implementation of WSUD at household level.
