Water Supply & Distribution

Hamilton Water is responsible for the treatment and distribution of clean, safe drinking water across the city, and the collection and treatment of wastewater and storm water.  Water is distributed to urban areas by pumping water from Lake Ontario or from municipal wells, through a central water distribution system to residential homes and businesses. The water distribution system includes approximately 2,075 kilometres of water mains, 13,073 fire hydrants, 20,860 water valves and 150,000 service connections.
