About this document
Toilet flushing represents a significant portion of the total water supplied to Australian cities and towns. This proportion only increases when water restrictions are in force. Toilets in Australia are, however, already relatively water-efficient. The average flush volume of a toilet sold today is about 50 per cent of what it was 25 years ago.
This study explores whether there are opportunities for even more water-efficient flush toilets than the current Water Efficiency Labelling and Standards (WELS) Scheme four star rated toilet models sold in Australia. It specifically examines what would be required to introduce WELS five and six star rated toilet models. The study addresses flush toilets solely and therefore excludes vacuum and dry toilets.
