About – Humber Wastewater Treatment Plant

One of four City wastewater treatment plants, the Humber treats "used" water that residents and businesses deposit down drains every day. Flushing toilets, taking a shower and running a washing machine, for example, produces wastewater. It travels through the sanitary sewer system, a network of underground pipes, to treatment facilities.
