How long a new sewer connection takes, step by step

01 /What are the steps in a new sewer connection?

Seven steps, in roughly this order, although cities name and group them differently. Knowing the order is what lets you overlap the ones that can run in parallel.

1. Zoning and permit route

   Confirm what the lot allows and which permit path the building takes: house-scale or multi-unit.

2. Servicing check

   Get the tie-in depth and location from records, film any existing service, and run any capacity pre-review the city requires.

3. Connection application

   Submit the connection or service application with drawings and pay the fees.

4. Locates

   Book utility locates before any excavation, and arrange private locates for lines the one-call service does not mark.

5. Tap and lay

   The public side is built by the city or its authorized contractor, the private side by your contractor, and the two are joined.

6. Inspect and test

   The city and the plumbing inspector see the work before backfill; camera video where required.

7. Records and sign-off

   As-builts, service cards and final acceptance.

02 /What waits do cities publish?

Few cities publish a full start-to-finish time, but several publish the pieces. As checked in September 2026:

Two published figures warn about peaks. Utility Safety Partners said on its home page, when checked, that response times may be 5 to 10 business days because of high volume. And Vancouver's 4 to 6 months is a scheduling window, not a fixed date.

03 /When should the application start?

During design, before the foundation depth is fixed. The tie-in invert decides how deep the building drain can be; a capacity pre-review can set limits on discharge or require fire-flow work; and the city's answer on reusing the old service decides whether you need a new connection at all. Vancouver requires its residential sewer and water permit application before the combined development and building permit, and Ottawa requires a service consultation before a coach house building permit, which shows how early cities want the conversation.

04 /Where does the connection fit in the build schedule?

Usually between demolition and backfilling the foundation. On an infill rebuild, the old services are dealt with before or during demolition, the new private side is laid while the lot is open, and the city's part is timed to meet it. Where the city builds the public side on its own schedule, as in Vancouver and Toronto, your contractor caps the private pipes at the property line and the building carries on; the connection is made when the city's crew or contractor arrives.

• Demolition: Winnipeg will not issue a demolition permit until services are abandoned or a deposit is paid; Saskatoon requires a licensed contractor to cut off services on demolition.
• Excavation: the building sewer leaves the foundation at its design depth, so it is laid before the foundation is backfilled.
• Public side: timed to the city's queue or your contractor's road permit.
• Occupancy: the connection and its inspections must be complete; plan for the records to be filed before the final inspection.

05 /Does it matter who builds the public side?

Yes: it decides which queue you are in. Where the city builds the public side, the city's own crew or contractor schedule is the long pole, and your contractor finishes the private side and caps it at the property line to wait. Toronto's 12 to 14 week target and Vancouver's 4 to 6 month window are both of this kind. The advantage is a known fee and no road work in your contract; the cost is that you cannot speed the city's crew up.

Where your own approved or licensed contractor builds to the main, as in Calgary, Saskatoon, Winnipeg and Halifax, the queue is mostly paperwork: the application, a servicing plan review where one applies, the right-of-way permit and inspection bookings. Halifax Water says it processes applications within five business days, and Saskatoon's pre-review answers within five. Once approved, the connection can be built in the same mobilisation as the private side, which is why contractor-built models can move faster on paper. Edmonton sits between: EPCOR schedules and builds the public side by quote, typically in 3 to 5 days of construction once it is on the calendar.

06 /What delays new connections most often?

1. A late application. Discovering the city's queue after the foundation is poured.
2. A wrong assumption about reuse. Budgeting to keep the old service and learning it must be replaced.
3. A shallow tie-in. Finding the main is not deep enough for gravity drainage from the planned basement, forcing a redesign or a pumped service.
4. Missed inspections. Backfilling before the inspector has seen the work; Winnipeg forbids backfilling until the City authorizes it.
5. Utility conflicts. Gas, communications or water lines where the new service needs to go, found only at locate time.
6. Revisions. Each round of drawing changes restarts part of a review clock; Toronto allows 10 business days per revision.

07 /How can you shorten the timeline?

Front-load the questions. Ask the city for the tie-in depth and its reuse rule in the first week of design. Film the existing service before demolition. Count the fixture load in the fixture load estimator so the size is settled before the application. Submit complete drawings, because incomplete ones restart clocks. And book the city's part as soon as the rules allow, because the public side is the longest queue in the cities that build it themselves.

Fees are usually due at application or before the work, so they belong in the early cash flow too; Toronto has you pay the estimated cost in advance. See the cost guide for the published figures.

Use the Service Connection Planner for your city's published timing, and request quotes from contractors who can tell you their current lead time for the private side.
