Eligible Richmond Hill residents can receive up to $1,500 toward the cost of installing a backwater valve through the City's Backwater Valve Subsidy Program. The valve lets sewage flow out but blocks it from flowing back in if the sanitary system overflows.
Why Richmond Hill homes need this
During severe storms, overloaded sewers can back up into basements. A backwater valve is a one-time install that protects Richmond Hill homes from that risk for decades.
