Rainwater as a Domestic Water Supplement in Scotland: Attitudes and Perceptions

Abstract

Aims: Water resources in Scotland are under immense pressure despite the perception that Scotland enjoys abundant rainfall and water resources. The transport and treatment of water utilizes high amounts of energy is which contradicts the UK government’s carbon neutral agenda. There is also the need to ensure reliable water supply to households whilst protecting the natural environment. The intent of this study therefore was aimed to explore the feasibility of rainwater harvesting (RWH) as a domestic water supplement in some selected peri-urban areas in Scotland by understanding people’s perceptions, attitudes and behaviour towards RWH systems; and the preference for a community or individual system. Methodology: Paper questionnaires were administered randomly to households using Private Water Supply (PWS) in three local areas: Highlands, Scottish Borders and Aberdeenshire over a period of 4 months. Results: The response rates for Highlands, Scottish Borders and Aberdeenshire were 28%, 27% and 19% respectively, with the latter being marginally below target. The survey responses revealed that participants were unlikely to use RWH for domestic purposes including drinking, bathing, dishes and laundry but felt RWH would be acceptable for most uses except drinking. These included non-potable uses such as gardening, car washing and toilet flushing. Conclusion: Most respondents were indifferent to implement RWH in their house if their neighbor used it or if it was a community set-up, but were willing to consider it if grant incentives were
