PDC Renewal/Replacement

If an existing Private Drain Connection (PDC) requires renewal, multiple options may be available to you. 



If your property is a single family detached, duplex, tri-plex, four-plex, five-plex or six-plex, the City offers an optional flat rate fee for Sewer Operations to renew the entire PDC from the sewer main to the property line.  The current fee is $5,000.  Alternatively, you can hire your own contractor to undertake a partial or complete renewal of your PDC.  Please note that a Permit for Approved Works (PAW) is required for any work occurring in the City Right-Of-Way. 

What Will the City Do?

As soon as payment is received, City Sewer Operations will:

  • Inspect the PDC with a sewer camera
  • Clean the PDC, if necessary
  • Determine the method of repair or replacement
  • Either open-cut replace, pipe-burst replace, or line the PDC
  • Restore to preconstruction condition

Payment and Application

Contact the City at 519-661-4570 (Monday to Friday 8:30 am to 4:30 pm).  Details can be provided over the phone, sent by fax or sent electronically.

PDC Replacement During A City Construction Project

If the City is undertaking a reconstruction project where the mainline sewer is being replaced, all existing PDCs connected to this sewer will also be replaced between the mainline sewer and a point approximately 2 metres behind curb (this may vary from project to project depending on other external factors such as trees).  The length of the remaining existing PDC will vary depending on a number of factors including the street Right-Of-Way, location of mainline sewer, and width of roadway.
