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.

摘要

水敏感城市设计 (WSUD) 提出了一个实现水敏感城市目标的过程。综合方法需要社区接受才能在家庭层面实施 WSUD。在南非开普敦和比勒陀利亚的 250 户家庭中进行了一项探索性比较调查，以确定雨水收集、灰水回收系统和透水铺路的实际吸收情况、影响吸收的因素以及实施 WSUD 相对于其他水的援助的有效性需求侧管理工具。在节水的中高收入房主中，雨水收集和中水回用的实际应用是显而易见的。尽管对数线性分析表明开普敦最近的干旱不太可能有助于提高吸收水平，尽管如此，实施 WSUD 的援助仍被视为第二个最有效的工具。提出了三个更系统研究的方向，以更好地为家庭层面的 WSUD 实际实施提供信息。
