Multi-unit Toilet Replacement Pilot Program vs. Actual Field Data

摘要

The Toilet Replacement Program is the measure with the greatest water savings in the City of Toronto’s Water Efficiency Program (WEP) and is expected to achieve a reduction of over 100 million litres of water per day by 2011. The Toilet Replacement Program is designed to encourage those replacing existing toilets in all property sectors to choose to install City approved ultra – low-flush models by offering a cash incentive. It is estimated that toilet use represents about 60% of the total volume of water used in a typical multi-unit residence, which is about 272 litres per day, for multi unit residential. Toilet replacement programs have been developed for the Single Family, Multi-unit (private and public housing) and the Industrial, Commercial, Institutional (ICI) sectors. Over 185,000 Cityselected toilets have been installed to date resulting in total annual water savings of approximately 44 million litres/day (ML/d). An ongoing monitoring program was established to measure the actual savings achieved. After installing about one third of the toilets for this sector, almost 50% of the total Multi-unit Toilet Replacement Program target for 2011 was achieved as of the end of 2004. An example of savings will be presented through various case studies of a variety of buildings
