Abstract

The Toronto Healthy House is a duplex dwelling in downtown Toronto, Ontario, Canada that is completely independent of municipal water and wastewater services. Water for potable use is obtained from the roof and yard surfaces, and grey water and black water are recycled for other uses. The capacity of the rainwater cistern was determined using a program developed for agencies of the Nova Scotia government. Rainwater is treated by dual filtration and ultraviolet disinfection. Monitoring results confirm that potable water quality meets Canadian Drinking Water Standards.
