Score is Grade A Plumber's own 0–1,000 rating, computed from review quality and volume, recent activity, owner replies and a verified Michigan licence. Google ratings and counts are shown as reported by Google and are not this site's own rating. A green ✓ means we matched the company to a current Michigan plumbing licence; “verify” means it is not in our register extract yet — check the state record. A blank is not a claim that a company is unlicensed.
Plumbing in Macomb County: water, sewers and permits
Across Macomb County, cities and townships buy treated water from the Great Lakes Water Authority (GLWA), drawn from the Detroit River and Lake Huron — confirmed in each community’s own annual water-quality report. [City of Warren 2025 Water Quality Report; Clinton Township 2025 Drinking Water Quality Report]
The Macomb County Public Works Office (21777 Dunham Rd, Clinton Township; 586-469-5325) runs 68 miles of sanitary sewer for more than 800,000 residents across 14 communities, through three drainage districts: the Macomb Interceptor Drain Drainage District (~600,000 residents, including Clinton Township, Shelby Township, Sterling Heights and Macomb Township), the 8.5 Mile Relief Drain district (Eastpointe and St. Clair Shores), and the Martin Sanitary district (Roseville and St. Clair Shores). The county bought the 38-mile interceptor from Detroit in 2010; flow goes to the GLWA plant in Detroit. [Macomb County Public Works — Wastewater Services]
The Chapaton Pump Station and Retention Treatment Basin, at the foot of Nine Mile Road in St. Clair Shores, is in a $27 million rehabilitation that adds 13 million gallons of storage and is expected to cut combined-sewer overflows about 38% — work Commissioner Candice Miller says will "prevent basement flooding for residents and businesses in the drainage district area." [Macomb County Public Works news release]
Under Michigan law (MCL 691.1419), a homeowner claiming sewage-backup damage must give the responsible government agency written notice within 45 days of discovering the damage, stating their name, address, the affected property and a description of the claim. Macomb County publishes no single backup-claim process — each city or township handles its own, so the first call is to your local water or public-works department. [Michigan Legislature, MCL 691.1419]

St. Clair Shores is an older postwar city: a median build year around 1955 and roughly 79% of homes built between 1940 and 1969 (derived from the city’s own service-line inventory file), which is why galvanized supply lines and clay sewer laterals are common here. [Derived from the City of St. Clair Shores service-line inventory (building-year column)]
Common questions
Who do I call after a sewer backup in Macomb County?
There is no single county claim line — each city or township handles its own. Call your local water or public-works department first, and remember Michigan law (MCL 691.1419) gives you 45 days from discovering the damage to file written notice with the responsible agency. [Michigan Legislature, MCL 691.1419]
Where does Macomb County’s water come from?
From the Great Lakes Water Authority — the Detroit River and Lake Huron — delivered through each community’s own mains, as stated in their annual water-quality reports. [Community water-quality reports (Warren, Clinton Township, St. Clair Shores)]
Who do I call about a sewer backup in Warren?
Warren runs its own wastewater plant, so a backup claim goes to the City of Warren Risk Management Division (586-574-4670), and Michigan law gives you 45 days from discovering the damage to file written notice. [City of Warren 311]
Does Clinton Township have lead water pipes?
No — the township’s 2025 inventory reports zero lead service lines (1,370 remain unknown), and it replaces any line found to be lead at no cost. You can look up your own pipe on the township’s map. [Clinton Township]
Who maintains the water and sewer mains in Shelby Township?
The Shelby Township Department of Public Works (586-731-5990) maintains more than 325 miles of water main and 175 miles of sanitary sewer; the county’s Public Works Office runs the larger interceptor the township drains into. [Shelby Township DPW]

How the score works
Each company earns a 0–1,000 score from its Google rating (shrunk toward the local average so a handful of 5-star reviews can’t outrank a long record), review volume, reviews in the last 90 days, how often the owner replies, and readiness — 24/7 service and a verified Michigan licence.
