Most metro Detroit basement flooding is sewer backup, and standard flood insurance does not cover sewer backup unless a general flood caused it (FEMA, FloodSmart). So the help that matters here is not a FEMA check, it is the handful of local programs that pay for the actual fixes: lateral repairs, backwater valves, sump pumps, drainage. Detroit runs the two biggest. As of July 2026, one is closed and one is open to nearly half the city, and telling those two apart is the single most useful thing this page does.
The two Detroit doors
Open: the Private Sewer Repair Program (PSRP). Up to $40,000 per home to inspect and repair your private sewer lateral, disconnect downspouts, and add a backwater valve and sump pump, at no cost, as a grant to owner-occupants and a forgivable loan to landlords. It started in January 2024 with $43 million in federal disaster-recovery funds, and a March 2025 expansion widened it from 22 to 97 Detroit neighborhoods, nearly half the city. You qualify with household income at or below 80 percent of the Area Median Income, a 1-to-4-unit home in a covered neighborhood, provable June 2021 flood impact, and a property outside the floodplain. Applications are rolling until the money runs out (check your address and apply, checked July 2026).
Closed: the Basement Backup Protection Program (BBPP). DWSD's program installed backwater valves and sump pumps at no cost in 11 flood-prone neighborhoods, 382 valves in Phase 1 alone. Its own page now says no applications will be accepted at this time, reopening only if new funding lands (DWSD program page, checked July 2026). If a contractor or a neighbor tells you the city will install your valve free, this is the program they mean, and today the PSRP is the door that is actually open.
Every program, with its real status
Each row was verified against the operator's own page in July 2026. Statuses change, so trust the checked date, not the folklore.

Which programs reach your community
Detroit (Basement Risk Index 92/100, ranked #4 of 116) holds three of the rows above to itself: the open PSRP, the closed BBPP, and the automatic Green Credit. That is not an accident. The city's own 311 records document more than 13,400 water-in-basement reports since 2023, falling hardest on its oldest, predominantly Black, lower-income ZIPs by nearly a factor of three, and the federal money follows the June 2021 disaster declaration.
Southeast Oakland County's RainSmart rebates cover the George W. Kuhn Drain District, which the county lists as all or part of Berkley, Beverly Hills, Birmingham, Clawson, Ferndale, Hazel Park, Huntington Woods, Madison Heights, Oak Park, Pleasant Ridge, Royal Oak, Royal Oak Township, Southfield, and Troy (Oakland County WRC, checked July 2026). Four of those are in our ten riskiest communities metro-wide: Pleasant Ridge scores 100/100, Huntington Woods 87, Ferndale 85, and Berkley 82, and most of the district also shows combined sewers in part. A rain barrel will not stop a sewer backup, but the district running a rebate program at all tells you what its pipes deal with.
Everywhere else in the tri-county, the honest answer is thinner: THAW's bill help, the 211 line, the insurance rider you buy yourself, and the 45-day claim window when the government's own sewer fails. Prevention you pay for out of pocket is covered in our 2026 cost guide, and the two fixes these programs install are explained in our backwater valve and sump pump guides.
