Public Acceptance and Preference Towards Rainwater Harvesting in Klang Valley, Malaysia

Abstract

This study explored the public acceptance and preference towards rainwater harvesting (RWH) in the area of Klang Valley. Self-administered questionnaires were used to obtain data from 109 respondents. An interview was also conducted on an individual representing a household with a RWH system. Respondents generally accepted that rainwater could be collected and reused for non-potable uses such as washing the porch and vehicles and watering the garden. While suggested WTP values of non-owners of the system fall below RM500, actual interview showed a homeowner spending a much higher amount for the system’s installation. Among the attributes of a RWH system preferred by respondents were affordability, safety and convenience. Added feature of a system preferred would be having a unit subsidized by the government. These findings may assist policymakers in finding ways to promote the development and use of RWH systems in the country.
