What is it?

The City of St. Catharines Flood Alleviation Program (FLAP) provides grants of up to $3,500 to homeowners who have or are at risk of having a sanitary back-up as a result of sewer surcharging.

FLAP consists of a grant to offset the cost of eligible work, which may include:

  • The installation of a backwater valve to stop sewage back-ups
  • The installation of a sump pump with a back-up pump (battery or water-powered)
  • The disconnection of weeping tiles from the sanitary sewer
  • The re-connection of these weeping tiles to the sump pump
  • All materials and labour associated with the installation of the protective devices

The maximum allowable amount funded by the City of St. Catharines is $3,500 per home.


  1. The homeowner contacts Citizens First at 905.688.5600 and provides the customer service representative with flood related information.
  2. Environmental Services staff will review the information to ensure it meets eligibility.
    • Reminder - FLAP is designed for homeowners who have, or are at risk of having, a sanitary back-up as a result of sewer surcharging.
  3. If the application is eligible, City staff will inspect the property to determine what work is required (e.g. installation of a sump pump, installation of a backwater valve).
  4. The homeowner is then responsible for getting quotes for the installation of the work required.
  5. The homeowner shares the quotes with the City. The grant amount given by the City will be based on the lowest quoted amount.
  6. Once approval is given, the homeowner can proceed with the installation work.
  7. Once work is complete, a plumbing inspector will check the work to ensure it has been installed correctly.
  8. Following the successful inspection, the City will issue the grant to the homeowner.


Each situation, home and solution is unique, so it's difficult to give a guaranteed timeline for each FLAP submission.

However, homeowners are advised that the entire FLAP process will take several months to complete.



To apply for FLAP or for more information on the program please contact Citizens First at 905.688.5600 or send an email to Citizens First
