Avoid Overloading the Sewer
Disconnect any rain gutter downspouts, weeping tiles and sump pit drainage systems that drain directly into the sewer system.
In the past, direct connections to sewers were acceptable, but now our wastewater treatment system serves more customers and additional rainwater can overload sewer pipes and treatment systems. This increases the risk of flooded basements and overflow into the environment. See our Wastewater Bypass and Overflow Reports.
Residential Inflow and Infiltration Subsidy Program (RIISP)
The Residential Inflow and Infiltration Subsidy Program (RIISP) provides financial assistance (subsidy) to residential property owners who have experienced or could potentially experience flooding of their basements from sewer backups during times of heavy precipitation.
The subsidy partially reimburses property owners who incur costs associated with installing one or more of the approved plumbing solutions covered by RIISP. The approved plumbing solutions:
- ensure you are compliant with regulations
- help minimize the potential for municipal sewer backup into your home
- help direct roof water away from foundations and protect basements from flooding
Learn more about inflow and infiltration on our storm water page.
