Canada Mortgage and Housing Corporation (CMHC), in partnership with 12 municipalities across Canada, conducted a pilot program to test dual-flush toilet technology in residential, commercial, and institutional settings. The study assessed water consumption and compared this to the existing 13 litre toilets as well as a number of single-flush 6-litre toilets. Overall toilet performance and customer satisfaction were also surveyed. Results indicated that on average, dual flush toilets saved 26% more than single-flush 6-litre toilets when used to replace non-efficient toilets.
