Greywater Rebate

Install a Greywater Reuse System and Get a $1000 Rebate

Greywater systems collect and filter the water from your shower or bathtub so you can reuse the water to flush your toilets. With a greywater system, you could use up to 30% less water and save money on your water bill.

A greywater reuse system automatically makes your home eligible for Blue Built Home certification.

Contact Us Before You Buy or Install a Greywater System

Please call us to ensure rebate funds are available, then read, sign and submit one of the forms below to tell us if you are planning to install a greywater system in a newly-built home or an existing home.

When we receive your signed form, we will send you written permission to participate in the greywater system rebate program.

Hire a Licensed Plumber

Your greywater system must be installed by a qualified plumbing contractor to qualify for a rebate.

Building Permits and Backflow Prevention

Your home must have a backflow prevention device installed by a licenced plumber, and you will need a building permit to install a greywater reuse system. Please contact our Building Services team for more information.

Submit Your Application, Proof of Purchase and Installation

Schedule a Final Plumbing Inspection

After your greywater system is installed, please contact the City’s Building Services team to schedule a final inspection. If your inspection is successful, you will receive a written notice.

We will send you a rebate cheque and Blue Built Home certification within four weeks of your completed inspection.
