Hamilton 3P Program to Prevent Basement Flooding - Backwater Valve and Sump Pump $2,000 Rebate

The City of Hamilton offers good news to its residents who wish to protect their homes from rainwater basement flooding. Through its 3P Program (Residential Protective Plumbing Program), the city guides homeowners and gives out financial assistance as they perform a number of plumbing installations to stop basement flooding as a result of sewer surcharging.

Recently, Hamilton has experienced more heavy rains and flooding than in the past years. This prompted the City Council to launch the 3P Program to encourage homeowners to take action. (The program includes backwater valve rebate.)

Below are important 3P details:

1. Homeowners become eligible for the program after disconnecting their downspouts and installing their own backwater valve, with sump pit and pump. But when doing so, homeowners should know the following:

a) Installing these plumbing features require inspection and a building permit. Securing a permit requires costs, but these too will be reimbursed by the city later on.

b) Installation must be done or in consultation with Hamilton-licensed plumbers and/or contractors

2. With the help of a licensed plumber/contractor, homeowners can perform the following works and later apply for the amount of maximum rebate specified:

a) Installing of an approved backwater valve with sump pit and pump, for a maximum rebate of $2,000

b) Getting an official CCTV inspection and assessment, for a maximum rebate of $500

c) Disconnecting downspouts, for a maximum rebate of $200

The City of Hamilton will cap its funding at the lowest estimate submitted. And to further provide convenience to homeowners, the City of Hamilton is also offering a 3P loan program

3. Finally, homeowners will be asked to submit three independent estimates from a licensed plumber/contractor.

Peel Region Backwater Valve Rebate - Prevent Basement Flooding in Brampton, Mississauga, Caledon

The Region of Peel encourages homeowners to construct their own sanitary backwater valve in order to protect themselves from basement flooding and it is providing a rebate amounting to $700 to all eligible homeowners.

A backwater valve makes sure storm water flows out from the house and into the sewer system, reservoir or dumping area. As water passes through the device, the valve closes to prevent backflow, thus preventing flooding. Although a backwater valve does not provide 100% guarantee, it can get the job done when installed properly by a professional.

Are you eligible for the rebate? First, you must:
  • Prove that you live in a flood-prone area by showing a past flood-related insurance claim
  • Have experienced and reported basement flooding due to rainstorm in the past
  • Have not already received a similar subsidy from the Region of Peel in the past
Second, you must satisfy program requirements by performing the following:
  • Disconnect all your downspouts to make sure the backwater valve will be installed properly. You might need to consult a licensed plumber on how to disconnect your downspouts. If disconnecting any or all is not possible, call 905-791-7800, ext 4409 to ask for an exemption.
  • Install an open-type sanitary backwater valve that has passed the Ontario Building Code. You can install the valve yourself if you have passed the necessary criteria. Otherwise, installation must be done by a licensed plumber. (To avoid getting scammed, know that a typical installation of sanitary backwater valve may range from $1,600 to $3,500.)
  • Secure a building permit from the City of Brampton, Mississauga or the Town of Caledon, signed by a municipal inspector. The permit should include the sanitary backwater valve model number.
  • Secure a signed sanitary backwater valve inspection from municipal inspector 
  • Complete the Sanitary Backwater Valve Rebate Program application form
Third, send the application form with the signed building permit and receipts to:

Sanitary Backwater Valve Subsidy Program
2 Copper Road
Brampton, ON L6T 4W5

After receiving your application, expect the Region of Peel to visit your home to assess your downspouts.  After having assessed that all your downspouts have been disconnected accordingly, expect your rebate in the mail after 6-8 weeks. (This does not apply if you applied for a downspout disconnection inspection.)
