Plumbing in Oakland County: water, sewers and permits
Oakland County communities get their drinking water from the Great Lakes Water Authority (GLWA) — Lake Huron and the Detroit River. The county Water Resources Commissioner (WRC) operates water systems for 15 communities, and some cities, like Royal Oak, buy through the Southeast Oakland County Water Authority (SOCWA), which in turn buys wholesale from GLWA. [Oakland County WRC — Drinking Water; City of Royal Oak Water & Sewer Overview]
The Oakland County Water Resources Commissioner (248-858-0958; One Public Works Drive, Waterford) maintains sewers for 22 municipalities and runs the county drains. The county operates the sewers for communities such as Farmington Hills and part of Novi, while Royal Oak, Waterford and West Bloomfield run their own local sewers and are billed by the county for conveyance and treatment. [Oakland County WRC — Sewer]
Much of southeast Oakland County drains to the George W. Kuhn (Twelve Towns) system, which serves all or part of 14 communities over 24,500 acres. In heavy rain the combined flow — typically more than 93% stormwater — is stored, screened and disinfected at the Kuhn basin before discharging to the Red Run Drain, a tributary of the Clinton River. This is the system that drives basement-backup risk across Royal Oak and its neighbors. [Oakland County WRC — George W. Kuhn Retention Treatment Basin]
A basement-flooding claim in a county-operated community is filed with the WRC in writing within 45 days of discovering the damage, on the PA 222 claim form (online or mailed), and must show a defect the county knew or should have known about, a failure to repair it, and that the defect caused at least half of the damage. Your sewer bill tells you which agency — county or city — maintains your sewer. [Oakland County WRC — Basement Flooding Claim]
City by city
Royal Oak
Royal Oak issues plumbing permits through its Building Division (203 S Troy St; 248-246-3210), with the permit portal at AccessMyGov (you request a PIN from the Building Department to link an account). [City of Royal Oak — Building Inspection]
Royal Oak buys its water from the Southeast Oakland County Water Authority (SOCWA), which buys wholesale from GLWA, and owns about 220 miles of water main. [City of Royal Oak — Water & Sewer System Overview]
Royal Oak is on a combined sewer — storm and sanitary flow mix into one pipe that drains to the county’s George W. Kuhn system. On a backup, call the Department of Public Service (248-246-3300); the city handles blockages in the main, while the homeowner’s lateral is the owner’s responsibility. [City of Royal Oak — Sewer FAQ / Street & Basement Flooding]
Royal Oak has lead service lines and an active replacement program that swaps lead or galvanized lines for copper at no cost. A 2023 city inventory listed 260 lead and 826 galvanized lines (plus ~1,783 unknown), with 811 replaced since 2019 at about $4,300 each and a goal of finishing by 2033. [City of Royal Oak — Lead Service Line Replacement Program; Water System Advisory Council (Nov 2023)]
Over half of Royal Oak’s single-family housing was built before 1960, so galvanized supply lines and clay sewer laterals are common — part of why its combined sewer and lead-line program are so active. [City of Royal Oak — CDBG Consolidated Plan 2021–2025]
Farmington Hills
Farmington Hills issues building, plumbing, electrical and mechanical permits through its Building Division (31555 W. Eleven Mile Rd; 248-871-2450), with applications filed online through BS&A. [City of Farmington Hills — Building]
GLWA supplies Farmington Hills water from Lake Huron and the Detroit River. [Oakland County WRC — Farmington Hills community page]
The county WRC operates Farmington Hills’ sewers. On a sanitary backup not caused by internal plumbing, the city directs residents to the Oakland County WRC, with a written PA 222 claim filed within 45 days; a private sewer lead is the owner’s responsibility. [City of Farmington Hills — Sewer Backup Information]
There are no known lead service lines in the Farmington Hills water system — Oakland County has required copper for service lines of 2 inches or less since 1957, and Michigan banned lead statewide in 1988. [Oakland County WRC — Farmington Hills community page]
Waterford
Waterford Township issues building, mechanical, electrical and plumbing permits through Development Services (5200 Civic Center Dr; 248-674-6238), using BS&A Online; inspectors are in the office 8–9 a.m. [Charter Township of Waterford — Development Services / Permits]
Waterford runs its own water and sewer systems through Public Works (248-674-2278) — 13 water treatment plants, over 350 miles each of water and sanitary sewer main and 63 pumping stations — with wastewater conveyed to Detroit through the Clinton-Oakland Interceptor. [Charter Township of Waterford — Public Works]
Waterford’s sewer is township-run, not on the county WRC operated list; the Public Works emergency line (after hours 248-618-7550) is the local contact for a water or sewer problem. [Charter Township of Waterford — Public Works]
Waterford submitted its service-line inventory to the state before the October 2024 deadline; physical verification found no lead lines beyond one known private-side lead line it plans to replace, and it put the chance that any single unknown line is lead at under 1.4%. [Charter Township of Waterford — Complete Distribution Service Material Inventory]
Much of Waterford’s housing stock was built between the 1950s and 1970s, so older homes there are more prone to aging-pipe maintenance issues. [Charter Township of Waterford — Master Plan, Residential Areas]
Novi
Novi issues plumbing permits through Community Development (45175 Ten Mile Rd; 248-347-0415) with online permits and inspections on BS&A; same-day inspection requests close at 3:30 p.m. [City of Novi — Inspections / Online Portal]
Novi buys water wholesale from GLWA and sends sewage to a county (WRC) interceptor for treatment, setting its own rates. [City of Novi — Water FAQ]
Only part of Novi’s system is on the county WRC list; the city funds operation of the interceptor it drains into. For a sewage backup, call 248-347-0495 in business hours (Police Dispatch 248-348-3088 after hours) and city staff walk you through filing a claim. [City of Novi — Sewage Backup (311)]
No lead service lines were identified in Novi’s water system — the city physically verified 373 lines for its October 2024 inventory. [City of Novi — DSMI]
Novi’s housing skews newer than the older Oakland cities — about 27,380 units in 2020, with building permits peaking between 2000 and 2005 — so lead and clay-pipe problems are rarer here than in Royal Oak. [City of Novi — Master Plan Housing (draft, 2022)]
West Bloomfield
West Bloomfield Township issues building and trade permits through its Building Division (4550 Walnut Lake Rd; 248-451-4818), with online application; a township plumbing inspector reviews private-side service materials. [Charter Township of West Bloomfield — Building, Planning & Development Services]
GLWA supplies West Bloomfield water through seven entry-point vaults; the township Water & Sewer Utilities Department maintains over 370 miles of water main, 300+ miles of sanitary sewer and 23 lift stations. [Charter Township of West Bloomfield — Water & Sewer]
The township runs its own sewer (the county handles conveyance). Under PA 222, a backup claim is reported to the Township Clerk within 45 days; the owner is responsible for the lateral from the home to the township main. [Charter Township of West Bloomfield — Water & Sewer FAQ]
West Bloomfield installs copper from the main to the curb stop and publishes its service-line material inventory and annual water-quality report; the township plumbing inspector approves private-side materials. [Charter Township of West Bloomfield — Water Quality Documents]
Over 70% of West Bloomfield housing was built since 1970, and more than half between 1970 and 1989 — newer stock than the inner-ring Oakland cities, which keeps lead-line risk low. [Charter Township of West Bloomfield — Master Plan (2010)]
Common questions
Who do I call after a sewer backup in Oakland County?
Check your sewer bill to see which agency maintains your sewer. County-operated communities (like Farmington Hills) file a PA 222 claim with the Water Resources Commissioner within 45 days; cities that run their own sewers (Royal Oak, Waterford, West Bloomfield) take the call themselves. Either way, Michigan law gives you 45 days from discovering the damage. [Oakland County WRC — Basement Flooding Claim]
Which Oakland County cities still have lead water lines?
It varies sharply by age. Royal Oak, with housing largely built before 1960, has hundreds of lead and galvanized lines and an active replacement program. Newer communities — Farmington Hills and Novi — report no known lead service lines. Waterford found only one. Age of the housing is the best predictor. [City of Royal Oak; Oakland County WRC (Farmington Hills); City of Novi]
Does Royal Oak have lead water pipes?
Yes — Royal Oak has lead and galvanized service lines and runs a free replacement program swapping them for copper; a 2023 inventory found 260 lead and 826 galvanized lines, with a goal to finish by 2033. Text a photo of your pipe to 248-459-8187 to check eligibility. [City of Royal Oak]
Who do I call about a sewer backup in Farmington Hills?
The county operates Farmington Hills’ sewers, so a backup not caused by your own plumbing goes to the Oakland County Water Resources Commissioner, with a written PA 222 claim filed within 45 days of discovering the damage. [City of Farmington Hills]
Does Waterford run its own water and sewer?
Yes — Waterford Township operates its own systems (13 water plants, 350+ miles each of water and sewer main, 63 pump stations) and conveys wastewater to Detroit, so local water or sewer problems go to township Public Works, not the county. [Charter Township of Waterford]
Does Novi have lead service lines?
No — Novi’s 2024 inventory, built on 373 physically verified lines, identified no lead service lines in the water system. [City of Novi]
Who is responsible for my sewer lateral in West Bloomfield?
The homeowner — the township maintains only the sewer main, and the lateral from the home to the main is the owner’s responsibility. A PA 222 backup claim is reported to the Township Clerk within 45 days. [Charter Township of West Bloomfield]
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.
