There is a perception that Canada has an abundant freshwater supply. In some regions of the country, where drought conditions do not exist, this is certainly the case. There are, at times, large volumes of freshwater available.
But this is by no means the case for the entire country.
Re-use of treated wastewater will significantly reduce the demand for freshwater and also eliminate or reduce the discharges, thereby reducing the contaminant loadings to the freshwater sources.
