Where does Toronto tap water come from?

Toronto tap water comes exclusively from Lake Ontario. It gets pumped to four distinct water treatment plants located around the city. These plants operate 24/7 to deliver over 1 billion litres of drinking water! Lake water is run through screens to remove large debris and then through filters to remove additional impurities. Depending on the treatment plant, water is disinfected by using either chlorine or ozone. Additionally, the Island Water Treatment Plant, which is located on Center Island, uses the consistently cool temperature from the lake to chill downtown buildings during the summer! After the disinfection process, water flows through a succession of filters such as gravel, sand, and carbon to remove impurities and more bacteria. In order to distribute the water all the way to everyone’s tap, chlorine, fluoride, ammonia and phosphoric acid are added. Chlorine keeps microorganisms out of the distribution system, fluoride to help prevent tooth decay, ammonia to turn chlorine into chloramine to reduce smell and taste of the latter, and finally, phosphoric acid is used to reduce the risk of lead leaching into drinking water. Once water enters Toronto’s distribution system, it is tested every 6 hours at dedicated water sampling stations. Water must comply with the health standards set out in the Safe Drinking Water Act set by the Ministry of the Environment and Climate Change (MOECC).
