Abstract This paper reports on the water and energy balances of a small ecosensitive subdivision in Brisbane, Australia. The 22-lot development is designed around individual and communal rainwater tanks, on-site greywater reuse, off-peak sewer pump outs, and energy and water efficient house design and appliances. Results to date are limited by time and occupied house constraints, but they clearly identified the importance of rainwater and greywater in substituting for potable water (up to 190 L/hh/year). However, this water self sufficiency came at the cost of specific energy use well in excess of that from centralised water and sewerage systems. Suggestions are made on how to offset these energy losses, and include greenhouse gas efficient hot water system and grid connected photovoltaics (PVs). Future monitoring will include the social attitudes of residents towards sustainable urban practices and composition of the various water streams (e.g. rain, greywater, sewage and storm flow).
