Basement Backup and Flood Protection

While the Detroit Water and Sewerage Department (DWSD) and the Great Lakes Water Authority (GLWA) are doing the big stuff to address the aging infrastructure and become more climate resilient, residents can do the small stuff to help protect your homes and property.

Did you know that basements are inherently prone to flooding if not protected? First, they are under the ground where water seeps. Second, if the foundation and drain tiles are not maintained, they can lead to basement flooding. Third, sewer lateral service lines that carry sewage from the home can also fail and backup into the house.

City of Detroit Residential Basement Backup Protection Program


What is the City of Detroit Basement Backup Protection Program?
Homeowners in 11 Detroit neighborhoods that have historically experienced basement backups during rain events are eligible to apply for this program.

With increasingly frequent and severe weather events, it is important for residents to take measures to protect your property. There are small steps you can take to reduce basement backups and flooding as outlined in the City of Detroit Basement Backup & Flooding Handbook.

Local, county and state government agencies are assessing implementation of climate resiliency plans.

Property owners should disconnect downspouts from the sewer system, and where necessary install a backwater valve and/or sump pump to help reduce the potential for basement backups at houses, especially for areas that experience a history of basement backups.

The City of Detroit is offering residential homeowners (owner/occupied and landlords of occupied residential houses and duplexes) who have property within one of the 11 identified neighborhoods, a Basement Backup Protection Program. This is not offered to commercial property or nonprofits. The neighborhoods are based on clusters of historic basement backups and flooding reported to the Detroit Water & Sewerage Department (DWSD).

Phase 1 of the Basement Backup Protection Program is currently offered to homeowners in the Victoria Park and Aviation Sub neighborhoods, which were the hardest-hit areas during the June 25-26, 2021 rain event and have a history of basement backups during rainstorms. Victoria Park is the lowest geographic point in the city and in a flood plane. Aviation Sub has a long history of backups and basement flooding. Phase 1 is underway and began in May 2022.

  • The contractors assigned to Phase 1 are:  Ben Washington & Sons, Cregger Mechanical Systems, DPI, Lakeshore Global, Plumberz North America LLC, QMB LLC, and Mr. Wiggles.
  • After signing the homeowner waiver, completing the deposit, and pre-inspection, the contractor will be assigned to the participating occupied house in Phase 1 (homeowners are to only reach out to the plumber assigned to their address).

View the map below for the neighborhoods that are eligible for Phase 2. This phase is scheduled to begin in 2022 and end by December 2024 or when the funding is exhausted. These neighborhoods are based on clusters of historic basement backups as well as funding availability.

The Detroit Basement Backup Protection Program is funded by the Detroit Future Fund, possible only due to funds approved by U.S. Congress and President Joe Biden for the American Rescue Plan Act. The Fund pays for the cost of the program, with the exception of the homeowner payment. No water and sewer rate dollars are used.

Once the work for the property under this program is approved by DWSD, the homeowner occupant or landlord will make a $100 non-refundable deposit per eligible occupied house. Homeowner occupants can have a waiver for the deposit if they are enrolled in the DWSD Lifeline Plan Water.

Homeowners that have residential property in either phase can apply now.

Please refer to the City of Detroit Basement Backup & Flooding Handbook for information on backwater valves and the other measures to reduce backups and flooding.

  1. Inspect sewer lateral service line with CCTV (camera)
  2. Disconnect downspouts and install extensions at least three feet from foundation
  3. Install backwater valve only if sewer lateral service line is in viable condition
  4. Install sump pump on properties where diversion is possible

  • No addition of another sump pump and/or backwater valve.
  • No plumbing repairs on the private property including inside the house and the water service line.
  • No homeowners in neighborhoods outside of the target areas will be eligible due both to funding capacity and based on historic basement backup data.
  • If you have a finished basement with flooring other than cement, this program will only cover repatching the cement floor – the City will not subsidize the cost for restoring any tile, wood, carpeting, other materials, and/or fixtures.
Requirements
  • This subsidy program is only for residential, non-commercial property (occupied houses and duplex homes).
  • Funding must be available at time of application – check this page to see if there is a notice that funding has been committed (exhausted). 
  • For Phase 1 eligibility, the homeowner must have an occupied house or duplex in Victoria Park or Aviation Sub neighborhoods.
  • For Phase 2 eligibility, the homeowner must have an occupied house or duplex in one of the 9 targeted neighborhoods as defined in the map shown above.
  • The homeowner will review and sign a waiver once initial approval of your application has been granted.
  • After the signed waiver is received, the homeowner occupant or landlord will receive an invoice and make a $100 non-refundable deposit. 
    • Homeowner occupants can have a waiver for the deposit if enrolled in the DWSD Lifeline Plan; you can apply if you are low or moderate-income and become eligible for the waiver if you get approved and enrolled in the plan.
  • DWSD will schedule an appointment for a pre-inspection by the City of Detroit Buildings, Safety Engineering & Environmental Department (BSEED), and must pass the inspection to be eligible to participate – depending on the phased schedule this occurs in 2022 or in 2022-2024.
  • After the inspection is approved, a licensed plumber, assigned by DWSD, will visit the property to inspect the private sewer lateral that services your home. At this time, the plumbing contractor will review a list of eligible flood mitigation upgrades through the Basement Backup Protection Program. 
  • Based on BSEED initial inspection and the plumber's assessment and estimate, DWSD will deny or approve the work to be performed under this program.
  • BSEED will issue a permit and inspect the final work.
  • All eligible basement flooding protection work must be performed by a contractor/licensed plumber contracted and scheduled by DWSD.
  • If the downspouts are disconnected, they must safely be routed onto grass or a flower bed, and not on cement or towards a neighboring house, which can be done under this program.
  • Any work performed by the homeowner themselves does not qualify for subsidy.
  • Disputes with respect to qualifying work will be resolved by the representative from DWSD.
  • The contractor will use material/fittings that are approved by the Detroit Building Code, including the backwater valve and sump pump specifically approved for this program.
  • DWSD will pay the authorized contractor upon completion of the work, including proper inspections.
  • If water bill arrears exists, account holder must agree to enroll into a payment plan or low-income assistance plan.
How do I Receive Approval?

Homeowner verifies their occupied residential house or duplex is in the defined area based on the map on this page, then apply online. Tenants cannot apply. Once DWSD has provided pre-approval, the homeowner takes the following steps:

  2. Homeowner must have paid DWSD the $100 deposit (waiver for Lifeline Plan) to begin the processes.
  3. Homeowner must allow BSEED to perform an inspection inside and outside the home.
  4. Plumber will share the estimate with DWSD for approval.
  5. DWSD will pay the plumber directly for the cost of the approved flood mitigation measures.
  6. Final inspection is required before the payment is approved and is provided directly to the plumber.
