New residential water - sewer service - disconnection - re-use - City property

The following information applies to:

  • the installation of the new water and sewer service connections/disconnections on City property subject to associated fees
  • owner initiated requests to service upgrade for existing service connections on City property (replacement) including properties with existing double or "Y" connections, where property owner would like to upgrade to a single connection. This will be subject to associated fees.

This procedure is not for those who want to apply under the Priority Lead Water Service Replacement Program (LWSRP). For the Priority LWSRP see: Priority Lead Water Service Replacement Program - LWSRP

The City does NOT replace or install water and/or sewer service connections on private property. This is the homeowner's responsibility. We do not refer property owners to contractors for work on private property.

If you are changing your water service on the private side from a half-inch service to a 3/4 inch (19mm) diameter water service it is recommended that you change the City side to match. Replacing both will provide you with the most benefit in terms of pressure and flow.

Visit the City of Toronto website for application requirements for both Residential properties and Industrial, Commercial, Institutional (ICI) & Multi-residential Properties.
