With the challenges of global warming, climate change and population growth, and increasing concern in the UK that the demand for wholesome water will soon begin to exceed supply, a study was conducted to survey the acceptability of introducing low flow water fittings to domestic buildings. The study included: an experiment to test public opinion about low flow water fittings, focus group, survey of manufacturers and installers, and a literature review of public attitudes and behaviour regarding water use. The results give an improved understanding of the barriers and enablers to water-efficient behaviour which is essential to the appropriate installation of low flow rate appliances and their acceptance by the public.
