Drainage Rebate

The City of Thunder Bay offers financial assistance for homeowners who take flood prevention measures including installing sump pumps, sewer back-up prevention valves and weeping tile disconnections. The rebate program is available to property owners whose homes are impacted by extreme weather events.

EcoSuperior delivers this program on behalf of City of Thunder Bay. New funds are allocated by City of Thunder Bay yearly, and rebates are available while funding lasts. Check EcoSuperior's Drainage Rebate webpage for current availability.
