ABSTRACT
The use of stormwater runoff for domestic purposes (rainwater harvesting; RWH) is increasing as part of the green building movement; however, significant barriers impede the widespread uptake of the technology. This paper reports on the results of stakeholder interviews conducted with representatives from municipal administrations, the building sector and commercial suppliers, identifying barriers faced by each party in implementing RWH. The most significant barriers were as follows: initial capital cost, liability for potential health risks, limitations on the end use of rainwater, the Building Code's poor differentiation between rainwater, greywater and non-potable water, and a lack of public environmental commitment. Health risks would be a paramount concern for public health officials, but were only a moderate concern for the majority of building practitioners interviewed. These barriers are elaborated upon and discussed in the context of technological lock-in of conventional water management systems and the resulting lack of capacity in alternate water management approaches. Flexible, iterative, reflective, and participatory processes are required to build capacity for sustainable urban water management.
