Decentralised water systems can readily contribute towards water environmental sustainability. It is important to be able to rate environmental sustainability of decentralised systems so that home buyers can have confidence on claims of water sustainability, builders can have guidance on how to improve sustainability, land developers can justify their marketing claims and regulators can assess and regulate promotion of water sustainability of decentralised water systems. The Environmental Technology Centre has developed a rating tool for such a purpose. The rating tool quantifies the volumes of water drawn from all sources and wastewater disposed or reused through all routes, compares these with best practice water use volumes for a decentralised system and arrives at a score out of 10 (equivalent to best practice). The algorithm for the rating tool is implemented using Excel workbook/ worksheets prompting users to enter required input values. Application to four case studies is presented.
