The City of Toronto is divided into six operating levels or zones which result in 12 separate pressure districts. The ground elevations in each zone were selected so that the water system pressure in the zone, under normal pumping conditions, varies from a minimum of 275 kiloPascals (kPa) to a maximum of 793 kPa.
Before submitting a service request with 311 Toronto to investigate low water pressure, please visit the City of Toronto website.
