Plumbing in Hamtramck is plumbing in tight quarters. The city covers about 2.1 square miles inside Detroit, held 28,433 people at the 2020 census, and has a median home built in 1938. Nearly two-thirds of homes went up in 1939 or earlier, and about one in five is a two-unit building, so a single sewer lateral often serves two households. Underneath, rain and sewage share the same pipes, and FEMA’s project description blames the city’s frequent basement and street flooding on a sewer too small for the population. Old pipe, shared buildings and an undersized sewer shape almost every call we get from here.
Prewar flats on a 2-square-mile combined sewer
The census counts 5,258 of Hamtramck’s 8,371 homes as built in 1939 or earlier. At about 13,600 people per square mile, houses sit close together, and a lateral repair can mean digging between two foundations with very little room. In flats and houses this old we expect a cast iron stack with lead-and-oakum joints, a clay tile lateral, and galvanized water piping that has been partly swapped for copper over the years.
Storm water here doesn’t come from a river. EGLE’s 2021 environmental assessment found no rivers, wetlands or floodplains inside the city limits, so when a Hamtramck basement takes water in a storm, it usually comes up through the sewer connection or seeps through an old foundation wall.
The public side is old too. The Department of Public Services owns about 41.9 miles of water and sewer pipe, and the city’s 2021 state filing described the water main under its rebuilt roads as about 100 years old. Hamtramck started replacing lead service lines in 2019. Its 2025 water quality report counted 577 known lead lines, 2,493 copper and 2,959 of unknown material among 6,029 active services, after 780 lead lines were replaced that year. If you’re not sure what feeds your house, ask the Department of Public Services, and take health questions to the state.
What Hamtramck basements and two-family flats need most
- Backwater valve installation
With flooding tied to an undersized combined sewer, a valve on a sound building drain is the private-side defense while the city adds relief sewers.
- Basement floor drain cleaning
A half-blocked floor drain in a prewar basement turns every surge in the street sewer into standing water, and in a flat it is often the one drain both units share.
- Sewer camera inspection
Clay laterals from the 1920s and 1930s crack and take roots, and a camera run shows whether the trouble is in your line, between two foundations, or past the property line.
- Galvanized pipe replacement
Old galvanized piping inside a flat narrows with rust until the upstairs unit loses pressure first, and it is separate from the city’s service line work at the curb.
- Plumbing for landlords and property managers
About 42 percent of occupied homes are rented, and the Building Department runs its own rental registration, so work in a two-unit building gets planned around two sets of tenants and the paperwork.
- Water heater installation
A two-family flat often has two tanks side by side in one low basement, each with its own flue, and replacing one means checking venting and clearances for both.
- Sewer line repair and inspection
At about 13,600 people per square mile, a broken lateral can sit in a narrow gap between two houses, so finding the exact spot before digging saves both foundations.
Mound Road into Hamtramck, and the first look in a prewar basement
From Stephens Rd we take Hoover Road south to 9 Mile, cross over to Mound Road and follow Mound south across 8 Mile toward Hamtramck’s east side. It’s one of the farther cities we cover, so we group visits here and tell you when you call where yours falls.
In the basement we check the floor drain, the cleanout and the stack first, then find out whether the building has one lateral or two and one water service or two. In a flat we also ask who else needs access. Plumbing permits go through the Building Department at City Hall, which runs separate permit portals for contractors and homeowners and takes rental registrations too. For storm backups, a backwater valve only makes sense on a lateral that’s in good shape, so a camera usually comes first.
Keyworth, the library and city hall along Hamtramck’s main roads
- Joseph Campau, the main commercial street, where the city’s plans extend a relief sewer north from Goodson toward Holbrook.
- City Hall, 3401 Evaline, home to the Building Department and the Department of Public Services.
- Hamtramck Public Library, 2360 Caniff.
- Keyworth Stadium, 3201 Roosevelt, opened in 1936 as Michigan’s first WPA project and owned by Hamtramck Public Schools.
- Conant Avenue, the city’s Bengali business district.
The relief sewer work matters most for basements. The city’s plans add a 60-inch relief line tying into the overflow structure at Joseph Campau and Goodson, and FEMA awarded $9.35 million for the next phase of relief combined sewers. Storefront kitchens on Joseph Campau and Conant sit on the same aging mains as the houses behind them, and any business with a backflow device answers to the cross connection program run out of City Hall. After a backup, the Department of Public Services posts a flood report form and a PA 222 claim form. Under that 2001 state law, written notice of sewer damage is due within 45 days of finding it.

Why does my Hamtramck basement flood in heavy rain?
FEMA’s description of the city’s relief sewer project points to an undersized combined sewer that can’t carry big storms, so water backs up toward the lowest drains in the house. Our article on what causes basement backups in storms explains the mechanics. The city also takes flood reports through the Department of Public Services.
How do I find out if my Hamtramck water line is lead?
Ask the Department of Public Services at City Hall. The city has replaced lead lines since 2019, and its 2025 report still listed 2,959 services of unknown material. For health questions, start with the city’s water quality report and the state’s MI Lead Safe resources.
