A Local Guide for DeWitt, MI Basements
The only thing that starts here is a request to be contacted. After one independent contractor reaches you, it explains what might suit your basement, and no one, including this site, can promise a basement that never takes on water.
As a referral and advertising service, the site does no basement work and prices nothing. It is not a contractor, plumber or anyone's agent, and holds no Michigan builder, maintenance and alteration or plumbing license. The contractor may pay a flat fee to advertise (waived for now as a trial); homeowners pay and get nothing.
About 1,800 Homes in DeWitt, MI
This page covers the City of DeWitt, home to about 4,800 people. DeWitt Charter Township, wrapped around the city, is its own government, so if you live in the township, sewer and permit questions go to your township office.
Captain David Scott, who moved from Ann Arbor in 1833, was the first settler. The State Legislature created DeWitt Township on March 23, 1836, and the county seat sat in the township until December 1857. DeWitt became a village in 1929 and a city in 1965.
Census survey data put the typical home at about 1985. About 9% were built in 1939 or earlier and 17% before 1960, a small older core among homes spread evenly over the 1970s, 1980s and 1990s, about 18% each. Roughly 78% of the 1,795 homes are single-family detached, and about 83% are owner-occupied, the highest share on this site.
Basement Fixes Around DeWitt, MI
- Aging sump pumps. A pump from a 1980s or 1990s build can wear out; a new pump, check valve or alarm is common work.
- Silted drain tile. Footing drains can clog over decades or may never have been tied to a working pit.
- Window wells. Wells that lack a drain or cover collect rain and snowmelt, which can then seep past the window.
- Settled backfill. Soil beside newer foundations can sink until the yard tips toward the house.

The Looking Glass River and DeWitt, MI Ground
DeWitt, MI lies on the Looking Glass River, which flows on to join the Grand. It also receives the treated water from the plant that handles the city's sewage. A nearby river is rarely why a basement gets wet; the soil around the walls matters more.
Glacial till underlies much of mid-Michigan. Ground like that can hold groundwater a few feet below the yard from fall until spring, where it rests against basement walls. In August 2018 the National Weather Service noted several inches around the Lansing area, yet spots that usually flood saw less water than normal because the soil was very dry. In July 2024 DeWitt received just over 2 inches, per the Lansing State Journal.
City Hall Handles Sewers and Permits in DeWitt, MI
The City of DeWitt sends its sewage to a Clean Water Plant run by a regional municipal utilities authority, and residents are billed quarterly. Sewer and permit questions go to City Hall, (517) 669-2441, at 414 E. Main Street. A floor drain pushing water up is a sewer matter for City Hall, not a waterproofing job.
Sumps, sewage ejectors and a home's sanitary sewer hookup all appear on the City's plumbing permit form for residences, a sign that tying either into a pipe is permit work for a licensed plumbing contractor. Digging or structural repairs may need their own permit; put each permit, and who pulls it, in the written agreement.

Local Questions
My home was built in the 1990s. Why is the basement damp?
Newer basements still take on water. Drain tile can silt up, a pump can fail or fall behind in a summer downpour, backfill can settle toward the walls and window wells can fill. Wet ground from fall through spring adds pressure. A contractor's visit can narrow down which one applies.
I live in DeWitt Charter Township. Does this page apply?
Michigan's rules on licenses, plumbing and contracts apply in the township just as in the city, and the address check above shows whether a request from your street is accepted. Sewer and permit questions go to your township office, not City Hall.
Where should my sump pump empty?
Outdoors, far enough from the foundation and the neighbors' yards that it won't wander back. A floor drain, laundry tub or the sanitary sewer is the wrong destination. When in doubt, check with City Hall or a licensed plumbing contractor before anything is connected.
What should a signed agreement say?
A Michigan administrative rule expects a contract signed by you and the contractor that spells out the cost, the scope and the materials. Ask it to give drain length, pump details, the discharge point, warranty terms and permits. If a sale over $25 was solicited and signed at home, you may be able to cancel up to midnight on the third business day after signing.
