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.
