Detroit Water and Sewer Connection Fees (2026)

The Detroit Water and Sewerage Department (DWSD) supplies water and sanitary sewer service to Detroit addresses and buys treated water and sewer treatment wholesale from the regional Great Lakes Water Authority (GLWA); GLWA bills DWSD and its other member communities at a wholesale rate and doesn’t publish a per-tap fee for individual homeowners, so DWSD’s own retail schedule is what a new Detroit house actually pays. For a new single-family home connecting to both water and sewer, DWSD’s published Schedule of Fees comes to $1,450 in the ordinary case: a $150 plan review, a $650 water permit inspection, and a $650 sewer permit inspection. Unlike many cities, Detroit’s schedule doesn’t price the tap or the meter by size — DWSD doesn’t charge a separate tap or meter fee at all, because the homeowner’s own licensed Master Plumber or contractor supplies the materials and performs the excavation, service-line installation, and main tap under DWSD inspection. The most important caveat: many Detroit infill lots carry an old, disconnected water service from a demolished house, and DWSD’s schedule doesn’t say whether reconnecting that line replaces or adds to the standard $650 water inspection fee — see the worked examples below.

Official Detroit fees in one table

The table below lists every DWSD charge we verified from the city’s Schedule of Fees and Penalties for fiscal year 2026-27 (effective July 1, 2026, unchanged from FY2025-26). Three rows form the standard new-tap case: the combined plan-review fee, which covers water and sewer together on one line, plus the separate $650 water and $650 sewer permit inspections. The rest are situational — a second review cycle, non-residential zoning, the reconnection permit for a reusable existing line, demolition-related water disconnection, and a stormwater plan review whose applicability to one home isn’t stated — and are flagged rather than folded into the default total.

Worked example for a single-family home in Detroit

Assumptions: a detached single-family home in Detroit’s “Residential Zoning, Four (4) Units or Less” tier, connecting to both DWSD water and sewer, tap and service line installed by a City-registered Master Plumber (water) and Master Plumber or registered contractor (sewer).

Published DWSD service-permit charges, single-family, effective July 1, 2026

Case A is the baseline: DWSD approves the plans on the first submittal, and both taps are brand new. Case B adds DWSD’s $75 fee per plan-review cycle beyond the first, only owed if DWSD sends the plans back for revision. Case C covers a common Detroit scenario: a lot where an earlier house was demolished and DWSD approves reusing the old water service line instead of a fresh tap. DWSD lists a separate $650 Water Service Line Reconnection Permit here, but doesn’t state whether it replaces the $650 Water Permit Inspection for the same job or is billed on top of it — budget $1,450 to $2,100 and confirm with DWSD Permits.

Why there’s no published tap or meter fee

DWSD’s own Water & Sewer Service Permit Application Guide states plainly: “Plumber/Contractor does all work under Detroit Water and Sewerage Department (DWSD) inspection, including supplying all materials, excavating, laying pipe, tapping of main/sewer, etc.” DWSD’s role is plan review, permitting, and inspection — not performing or pricing the physical connection. The service line, tap, and meter setting are a private contract with the homeowner’s licensed plumber, which is why they aren’t DWSD line items and aren’t broken out by meter size the way many other cities’ tap fees are.

Costs outside the Detroit fee schedule

DWSD’s charges cover plan review and its own inspections. Everything else — materials, labor, excavation, the service line, and the physical tap — is priced privately by the homeowner’s licensed plumber or contractor, and a Right-of-Way permit from City of Detroit DPW (or MDOT/Wayne County Road Commission, depending on the street) is required for every new tap with no dollar figure published. National estimates (methodology):

• Water service line: $30–$150 per foot, typical $50. DWSD requires 5 feet of minimum pipe cover and caps service lines at 130 feet without a waiver.
• Sewer lateral: $50–$250 per foot, typical $100. DWSD requires new sewer taps to be 6 inches in diameter with 4 feet of minimum cover.
• Street cut or bore: $1,000–$10,000 per crossing, typical $4,000 — relevant if the tap opens a paved street rather than an alley.
• Plumbing permit: $100–$1,300, typical $300, issued by the City of Detroit’s Buildings, Safety, Engineering, and Environmental Department (BSEED), not DWSD.
• Electric service: DTE Energy supplies electricity in Detroit. We found no published new-service connection fee for a standard single-family home on DTE’s site — ask DTE directly for your address.

Paying Detroit fees: timing and process

DWSD’s process runs plan review before permit, and permit before physical work. The Master Plumber (or an authorized agent) submits engineering plans through DWSD’s online portal; a fire-line project also needs a flow test, hydraulic calculations, and Fire Marshal approval first. Once DWSD approves the plans, the applicant gets a ROW permit, then files the Water and Sewer Service Permit application with a property legal description, the plumber’s or contractor’s City registration and insurance, and signed statements of understanding. DWSD invoices the $150 (or $700 non-residential) plan-review fee here, payable at DWSD’s customer portal; a complete package becomes an issued permit in about 3–5 business days, valid one year. The plumber or contractor then does the physical work and must call DWSD’s inspection line at least 7 business days before backfilling — that inspection is what the $650 water and $650 sewer fees pay for. Finally, the Master Plumber calls DWSD’s Permit Unit at least 5 days ahead to schedule the water meter-set appointment; DWSD sets the meter itself, and we found no separate published fee for it.

Detroit fee changes to watch

• DWSD’s FY2026-27 Schedule of Fees (effective July 1, 2026) kept the plan-review, inspection, and reconnection-permit amounts identical to FY2025-26 — no increase this cycle for a single-family tap.
• FY2026-27 added a new “Easement Encroachment Permit Fee” ($300) not on the FY2025-26 schedule; its relevance to a standard new tap isn’t stated.
• Figures here are current as of our September 26, 2026 check. Fees are set by the Detroit Board of Water Commissioners and the document itself says they’re “subject to change.”
