Watermains are underground pipes that deliver a steady supply of fresh, clean drinking water to residents and businesses.
The City is improving the watermain distribution system through the following programs:
The City replaces approximately 35 to 50 km of watermains each year.
A combination of factors are considered when prioritizing replacement, including: pipe age and material, break frequency, operational performance, future growth, and coordination with other construction projects (i.e. gas, hydro) in order to minimize cost and disruption to the community.
The City rehabilitates more than 130 km of watermains each year to help extend the life of its watermains. This is done through the following methods:
Residents should call 311 to report a watermain break. Toronto Water staff are available 24 hours a day, seven days a week to respond to calls. Depending on the severity of the break, repairs can take up to 24 hours and sometimes longer.
The City flushes watermains to help clean out mineral deposits and sediment that have built up over time.
