Abstract The new building, the future Centre for Environmental Science and Engineering (ESE building), scheduled to open in 1998, has provided an opportunity for a WATGreen team to initiate the study of a rain water system for the building. The proposed rain water system would involve using rainfall that would otherwise be collected as surface runoff. With a rain water system, 'free' rainwater would instead be stored in a rain water storage or retention tank and then used for flushing toilets, which does not necessitate the use of clean chemically treated water. The use of a rain water system on the University of Waterloo campus not only promotes water conservation, but it also promotes an aspect of sustainable development of such an irreplaceable resource.
