Abstract

ABSTRACT: An integrated approach to Water Sensitive Urban Design and Sustainable Drainage Systems requires community involvement. Mooikloof is a low-density upmarket residential estate with one-hectare properties and large detached houses, but with no stormwater infrastructure, offering a unique case study of uptake of source controls. Using the Theory of Planned Behaviour and an online survey, we examined property owners' current and intended uptake of rainwater harvesting, green roofing, permeable paving and retention ponds, and factors influencing uptake. Owners showed noticeable levels of uptake of certain controls, influenced foremost by positive attitudes and peer pressure with site hydrology also playing a role. Some owners may need assistance to implement certain controls, whereas others may need incentivising or behavioural nudging towards uptake. We conclude with recommendations for further research and the practical implementation of source controls on site or individual residential properties in similar contexts.
