Sump Pumps and Basement Water in Toledo: Rules, Grants and Upkeep
Page date: November 15, 2026.
Water in a Toledo basement usually comes from one of two places: groundwater and rain soaking through or under the foundation, or sewage backing up through a floor drain. A sump pump deals with the first. A backflow device or standpipe deals with the second. Knowing which problem you have decides what fix makes sense, whether a City grant can help, and where the water is legally allowed to go.
This guide covers Toledo's discharge rules, the City's basement flooding grant, and practical sump pump upkeep before winter and spring.
Two kinds of basement water
The City of Toledo says basement flooding or sewer odor "may be caused by a broken or obstructed sewer line, or by unusually heavy rainfall." (City of Toledo, Basement Flooding)
- Groundwater or storm water. Clear water that seeps through walls, rises through floor cracks, or collects in the sump pit. Drain tile around the footing carries it to a sump crock, where the pump lifts it out.
- Sewer backup. Gray or dirty water, often with odor, coming up through a floor drain or the lowest fixture. This can be a blockage in your own sewer lateral or an overloaded public sewer during heavy rain.
The difference matters. Toledo's basement flooding grant covers devices that keep sanitary sewage out of basements. It does not cover "work to prevent strictly groundwater or storm water flooding such as wall waterproofing, footer drain cleaning or replacement." (City of Toledo, Basement Flooding Grant Program)
Where a sump pump may discharge in Toledo
Two parts of the Toledo Municipal Code shape where sump water can go.
It may not go into a sanitary sewer. TMC 930.04(a) states that no person shall discharge to any sanitary sewer "any unpolluted water such as, but not limited to, storm water, ground water, roof water runoff, subsurface drainage, footer drain discharge." If the City finds such a connection, it issues a written order to remove it within 90 days. (TMC 930.04) Connecting a sump pump to a laundry tub or floor drain that runs to the sanitary sewer falls into this category.
Replacement foundation drainage has specific options. TMC 1745.03(d), part of the City's Housing Code, says replacement foundation drainage "shall not drain to daylight exterior of the building envelope." Replacement drain tile must drain by gravity to a storm sewer or combination storm-sanitary sewer, or to a sump pump crock. Sump pump discharge of foundation storm water must go by direct underground connection to a properly sized dry well, to a storm sewer or combination storm-sanitary sewer outside the structure, or to a contained landscaped area such as a rain garden or retention pond. In every case "a back-flow prevention system, or check ball valve, must also be installed," the discharge may not flood neighboring properties, and it may not be made into the public right-of-way. Violations are treated as a public nuisance. (TMC 1745.03)
Toledo's code refers to both sanitary and combined public sewers (TMC 927.01), and defines combined sewers as sewers receiving "both storm, surface and ground water drainage and sewage." (TMC 930.011) Whether your street has a storm sewer, a combined sewer or neither affects which option fits your lot. The City's Division of Sewer and Drainage Services maintains 1,100 miles of sanitary sewers, 986 miles of storm sewers and 64 miles of ditches. (City of Toledo, Sewer and Drainage)
The basement flooding grant
If sewage has backed up into your basement because a public main sewer was overloaded, the City offers a grant toward prevention. From the City's program page (City of Toledo, Basement Flooding Grant Program):
- What it is for: work "intended to prevent backup of sanitary sewage into basements," isolating and elevating basement sewer connections with devices or methods "such as standpipes, check valves, sewer or plumbing modifications, and sump pumps."
- Who is eligible: owners of property in the City of Toledo "that experiences sewer backups from overloaded main sewers." There is no age or income requirement, though those factors can affect the amount.
- How much: the City covers the first $1,000 of eligible work, then matches the second $1,000 50/50, up to a $1,500 maximum. The maximum is $2,000 for Homestead Exempt owners or Home Energy Assistance Program recipients. The grant is not repaid.
- Not covered: insurance deductibles, replacement of damaged property, cleanup costs, sewer lateral repairs or cleaning, and groundwater or storm water measures such as wall waterproofing.
- Process: apply with at least two written quotes, no more than 60 days after work is complete. The City must verify a public sanitary backup before approval. Owners may do the work themselves when permitted, or hire a contractor licensed for it, and the work needs any required inspections.
Choosing and maintaining a sump pump
General points that apply to most Toledo basements:
Test it before it matters. Pour a bucket of water into the pit and watch the float rise and the pump start. The water level should drop quickly and the pump should shut off on its own. Do this in fall and again before spring thaw.
Check the discharge line in winter. An outdoor discharge line that holds water can freeze solid. Toledo's average first freeze is October 17 (NWS Cleveland) and the City designs for a winter temperature of 1°F (City of Toledo, Building Construction), so any above-ground section needs to slope so it drains fully between cycles.
Know the check valve. A check valve on the discharge pipe stops water from running back into the pit. Toledo's code requires a back-flow prevention system or check ball valve on qualifying sump discharge. (TMC 1745.03) If you hear the pump cycling on and off rapidly, a failed check valve is one common cause.
Plan for power outages. Heavy storms that bring water also knock out power. A battery backup pump or a water-powered backup (which needs adequate city water pressure) keeps water moving when the main pump cannot. Test backup systems on the same schedule.
Keep the pit clear. Silt, gravel and debris can jam the float or clog the intake screen. A lid on the pit keeps debris out and reduces humidity.
Watch the age. Pumps wear out. If yours runs constantly, hums without pumping, or has not been tested in years, plan a replacement before the wet season instead of during it.
If your basement is flooding now
The City asks residents to call Engage Toledo at 419-936-2020 "right away" for emergency flooding issues, and says help is available 24 hours a day. (City of Toledo, Basement Flooding)
Its guidance also covers next steps:
- Find the obstruction. The City suggests having a private licensed sewer cleaner check the line. Obstructions between the main sewer and the home are the homeowner's responsibility; problems in the public right-of-way or sewer easement are the City's. Obstructions can be cleared by the homeowner, a licensed sewer tapper, a licensed sewer cleaner or a licensed plumber; repairs can be made by a licensed sewer contractor only.
- Clean up safely. Wear boots and gloves, remove debris, clean floors and walls with soap and warm water, then go over affected areas with a mixture of 1 tablespoon vinegar, 1 cup bleach and 1 gallon of water, and rinse. Throw out any food exposed.
- Electrical safety. If you had to evacuate, turn off main power switches and unplug appliances until a qualified electrician inspects them, and check gas appliances and pilot lights for leaks before relighting. If you smell gas, leave and call 911 and the gas utility from outside.

Permits and hiring
Toledo's Division of Building Inspection requires permits for plumbing work, with inspection before work is enclosed, and allows homeowners to pull plumbing permits only for a one-family, owner-occupied home where they do the work themselves. (City of Toledo, When are permits required) If you hire someone, confirm they appear on the City's registered plumbing contractors list. The grant program also links its own contractor list from the program page.
