Short answer

In Halifax, the applicant pays for the excavation and pipe from the main to the building on a new sewer service connection, and Halifax Water makes the tap. New buildings apply through an HRM building permit, existing single homes and townhouses upload a New Connection and Renewal Application, and multi-unit projects follow Section 8 of the Design Specifications. Regional development charges apply to net new units.

Key takeaways
  • Halifax Water's 2026 Regulations make the applicant pay for excavation and pipe from the main to the building, while Halifax Water does the tap (as checked September 2026).
  • Published Halifax Water fees include $375 for tapping a 19 to 50 mm service and $175 per inspection visit.
  • An existing service at least 30 years old must be replaced at the owner's cost when a redevelopment or a permit over $100,000 is involved.
  • The Design Specifications require a separate connection for each building, except an ancillary building on the same property, and CCTV before a wastewater lateral is reused.
  • HRM's second unit incentive offers up to $10,000 toward water and sewer connection costs, with applications due by October 11, 2026.
Four ways a new service connects to the public systemFour connection types. A wye or tee fitting set into a main while the main is being built. A saddle tap, where a hole is cored in an existing main and a saddle fitting is clamped or bonded over it. A connection at a manhole, usually reserved for larger services. A branch that joins another building sewer, which the plumbing code allows for an ancillary building on the same property and which some cities restrict. The municipal standard decides which one your service gets.

Fig. 1Four common ways a new service meets the public system: a fitting set in a new main, a saddle on a cored hole in an existing main, a connection at a manhole, or a branch into another building sewer where the code and the city allow it.

01 /Who does what on a new Halifax sewer connection?

The applicant pays for the excavation, pipe and related work from the main to the building, and Halifax Water makes the tap on its main, under Halifax Water's Regulations effective January 1, 2026 (as checked September 2026). So the owner's contractor digs and lays the service; Halifax Water connects it and inspects.

The Regulations set the utility's charges: $375 to tap a 19 to 50 mm service and $175 per inspection visit. If your project changes the use of a building, Halifax Water may require a sizing determination or a hydraulic analysis before it approves the connection, so raise any change of use early.

Building sewer and lateral in cross-sectionA house stack drops to the building drain, passes a cleanout and optional backwater valve, then the lateral slopes under the property line to the municipal main. Ownership typically splits at the property line but varies by municipality.

02 /Which Halifax Water application route fits your project?

It depends on whether the building is new and how many units it has. New buildings go through an HRM building permit; existing single homes and townhouses upload a New Connection and Renewal Application to Halifax Water; multi-unit projects follow Section 8 of the Design Specifications (as checked September 2026). Halifax Water's page gives five business days for the application route; confirm what that period covers.

The one-connection-per-building rule mirrors Article 2.1.2.4 of the National Plumbing Code of Canada, which requires each building to be connected separately but lets an ancillary building on the same property share. Nova Scotia's adopted code edition was not verified for this guide, so confirm the edition in force with HRM. For how a backyard suite ties in, see laneway and garden suite sewer options.

Three ways to service a backyard or laneway suitePlan view of a lot with a main house near the street and a backyard or laneway suite near the lane. Route A runs the suite's building sewer forward to join the main house's building sewer; the National Plumbing Code lets an ancillary building on the same property share the service. Route B gives the suite its own service to the street main. Route C connects the suite to a main in the lane, where one exists and the city permits it. Each route has its own length, depth and fall to check. STREET LANE MAIN?

03 /What does a new Halifax connection cost in charges and fees?

Beyond tapping and inspection, the largest public charge is the regional development charge, which for a single home or townhouse is $6,126.84 for wastewater and $1,921.82 for water (as checked September 2026). It applies only to the net increase in units, so a rebuild that replaces one home with one home should not add a charge for that unit.

Regional development charge, secondary suite$2,103.71 wastewater; $659.86 waterSeptember 2026

Halifax Water says the development charges are frozen, and that its 2026 application to update them is suspended pending an extension of the freeze beyond November 9, 2026. Check the rate on the day you apply. HRM's second unit incentive, funded through the Housing Accelerator Fund, offers up to $10,000 toward water and sewer connection costs for a new suite; applications close October 11, 2026 and work must be complete by April 1, 2027.

For private work, 2026 network planning ranges run $600 to $1,000 per metre of trench and pipe at shallow depth and $1,000 to $2,000 per metre when deep or under pavement, plus $500 to $2,000 for mobilisation and locates and $500 to $15,000 or more for restoration. The new sewer connection cost guide shows how these combine.

04 /When must an old service be replaced instead of reused in Halifax?

When the service is at least 30 years old and the project is a redevelopment or carries a permit worth more than $100,000, Halifax Water requires replacement at the owner's cost under sections 51(5) and 61(9) of its Regulations (as checked September 2026). Younger services may be reused, but a wastewater lateral needs a CCTV inspection first, according to the Design Specifications.

Four questions before reusing an existing sewer serviceAn existing service runs from an old house footprint to the main. Four questions are stacked beside it. First, does the city allow it to stay on a redevelopment? Second, what is it made of and what condition is it in, based on a camera video? Third, is it big enough for the new fixture-unit load at its slope? Fourth, does its depth and position suit the new foundation? A no to any of them usually means a new service, and the old one is abandoned the way the city specifies. OLD HOUSE(to be removed) EXISTING SERVICE MAIN 1ALLOWED TO STAY?some cities require a newservice on redevelopment2MATERIAL + CONDITIONcamera video, age, clay,fibre, cast iron, defects3BIG ENOUGH?new fixture-unit load vssize and slope (NPC table)4IN THE RIGHT PLACE?depth and position suitthe new foundation ANY "NO" → A NEW SERVICE; THE OLD ONE IS ABANDONED AS THE CITY SAYS DECISION AID · ILLUSTRATIVE · THE MUNICIPALITY DECIDES REUSE CAN THE OLD SERVICE TAKE THE NEW BUILDING?

That rule catches many infill projects, since a new house or a substantial renovation will usually exceed $100,000 and any service laid before about 1996 is already past 30 years. Get the service age from your records or Halifax Water before you budget. Reusing an existing sewer service explains what a camera run should show.

05 /How deep are Halifax services buried?

Halifax Water's 2025 Design Specifications set a minimum cover of 1.6 m for water services and 1.2 m for wastewater and storm services (as checked September 2026). Where water and sewer share a trench, the water line sets the trench depth, so budget for the deeper of the two.

06 /What should you ask Halifax Water and HRM before you design?

  1. Does my project go through an HRM building permit, the New Connection and Renewal Application, or Section 8?
  2. How old is my existing service, and does the 30-year replacement rule apply?
  3. Will a change of use trigger a sizing determination or hydraulic analysis?
  4. Can my backyard suite connect to the main dwelling lateral, and does the lateral have capacity?
  5. What regional development charge applies on the day I apply, given the freeze?
  6. Which plumbing code edition does HRM apply to the private drain?

Test your building and fixture mix in the service connection planner, then request private-side quotes once Halifax Water has confirmed the route.
