Sewer line replacement: the one published price, and who pays for which part
Sewer line replacement is a large repair on the private side of a house’s plumbing, and one with very little published pricing. Contractors quote per job; nobody publishes a Canadian average; and the scope — open-cut, pipe-burst or lining — is decided only after someone has looked down the pipe.
One Canadian city does publish a price. London will replace a Private Drain Connection itself for a flat fee, payable over ten years on the tax bill. This page starts there, then sets out who owns which part of the pipe in eight cities, when a city pays for part of your side, the three methods, and what insurance does and does not do.
The short version
- London replaces a Private Drain Connection for a 2026 flat rate of $7,250, payable as a lump sum or on property taxes over ten years.
- London’s crews inspect with a camera first, then open-cut, pipe-burst or line — the method follows the pipe’s condition.
- Who owns the pipe decides who pays: property line in five of the eight cities here, the main in three.
- Service line coverage, where you have it, is the cover written for a failed pipe. Replacing an old one is maintenance.
Three methods, several names
| What you would say | What the quote or city calls it | What it changes |
|---|---|---|
| Digging it up | Open-cut replacement | Excavation along the pipe; the most disturbance. |
| Trenchless | Pipe bursting | A new pipe pulled through the old one; London lists it by name. |
| Relining | Lining / cured-in-place | London: eliminates the need to dig up the original pipe. |
| My sewer pipe | Private Drain Connection (London) / lateral / service line | The pipe being replaced. |
| Camera first | Inspection with a sewer camera | How the method is chosen. |
| Paying over time | Flat-rate fee on property taxes | London, over ten years. |
The one published price
City of London, Sewers and wastewater · 2026
For the City's own replacement of a Private Drain Connection, available to residential single-family homes and duplex to six-plex properties. Once paid, the City says, Sewer Operations will inspect the connection with a sewer camera, clean it if necessary, determine the method, and open-cut replace, pipe-burst replace or line it, then restore to preconstruction condition. Page last modified March 30, 2026; read through a fetch service. It is the only installed price for a sewer lateral that this site has found published by a Canadian city.
That is a real number, with a real scope attached, published by the city that will do the work: inspection, cleaning, the method decided on the pipe’s condition, and restoration. It is one city’s price, for its own crews, and it is not a Canadian average — but it is the only installed price for a sewer lateral this site has found published by any Canadian municipality, and it is a useful reference against any private quote in Ontario.
Two conditions of London’s service are worth noting. It is available to residential properties from single-family homes up to six-plexes. And because London makes the homeowner responsible for the entire lateral, the flat rate covers a longer run of pipe than an equivalent job would in a city that splits at the property line.
City of London, Sewers and wastewater · 2026
The City is responsible for the sanitary sewer main within the roadway in front of the property. This is the opposite of Ottawa, where the owner's responsibility stops at the property line and the City's runs from there to the main. The same failure under the same boulevard is the homeowner's bill in London and the City's in Ottawa.
Whose pipe it is decides who pays
| City | The owner’s side ends | Help published for the owner’s side |
|---|---|---|
| London | At the main — the entire lateral | City replacement at a $7,250 flat rate (2026), payable over ten years |
| Hamilton | At the main — the whole lateral | One-time reimbursement where City-tree roots damaged the private portion |
| Winnipeg | At the main, including under the street | City-arranged repair under the street for eligible owner-occupied homes |
| Ottawa | At the property line | The City handles City-tree root and City-property cases |
| Calgary | At the property line | None found |
| Edmonton | At the property line | EPCOR waives service fees if the problem is on the public portion |
| Saskatoon | At the property line | Cost-sharing only if you replace rather than repair a non-compliant pipe |
| St. Catharines | At the property line | None found for the private side |
City of Winnipeg, Private sewer pipe responsibilities · 2026
The furthest a Canadian city on this site pushes the owner's side of the line: under the road. Winnipeg runs a repair-assistance programme for the part under the street, limited to owner-occupied single-family and two-family homes; properties outside it are “responsible for all sewer repairs, even if the problem is under City property”.
The same collapsed section under the same boulevard is a City repair in Ottawa, the owner’s in London, and in Winnipeg a City-arranged repair for eligible homes even though the pipe is the owner’s. Establish which rule applies before anyone quotes.
When a city pays for part of your side
City of Saskatoon, Bylaw No. 8880, s. 10(2)(c) · 2024
The by-law makes an owner whose failed connection is made of non-compliant materials eligible for any City cost-sharing policy only if they replace their portion. Repair it instead and the door closes. This site found no current City cost-share programme for sewer connections; the one it did find is for lead water lines.
Saskatoon’s by-law is the sharpest version of a general rule: the help, where it exists, is for replacing, not patching. If a camera shows an old pipe of a material the city no longer accepts, choosing a cheaper repair can close the door on whatever cost-sharing the city offers.
City of Hamilton, Sewer Back-Up and Blocked Drains (archive copy of June 4, 2026) · 2026
Part of Hamilton's definition of a qualifying defect, together with a structural deficiency in the public portion. Where the private portion is affected by City-tree roots and the owner replaces or rehabilitates the entire private portion, the City says a one-time reimbursement of part of the cost may be available, up to a maximum set in its Sewer and Drain By-law; the page gives no figure and this site did not find one.

City of Toronto, Drain Grant Appeal staff report (PDF), January 24, 2007 · 2007
The Council amendment of July 2006 to a policy that had assisted owners with repairs where a blockage resulted from City-owned tree roots. This is a 2007 document; this site could not confirm the grant still exists, and Toronto's current blocked-drain page does not mention it. Reported as history, not as an offer.
The water pipe coming in is a separate question with its own programmes. Where it is lead, Hamilton lends, London puts the cost on the tax bill and Saskatoon shares it — see lead water service. Replacing the sewer and water services in the same trench is worth asking about.
Lining or replacing
City of London, Sewers and wastewater · 2026
The City adds that if the Private Drain Connection has collapsed or is severely damaged, there may be no other solution than to replace it. Lining versus replacement is the single largest swing in what a failing lateral costs, and it is decided by the pipe's condition rather than by preference.
The method is decided by the pipe, not by preference. A pipe still sound enough to hold its shape can be lined, and nothing is dug up. A collapsed or badly broken pipe cannot be lined, and has to be replaced — by open cut or by bursting a new pipe through the old path. That is why every honest quote starts with a camera inspection, and why London’s own service puts the camera first.
- Ask to see the footage the method was chosen from.
- Ask where the work stops: at the property line or at the main — which depends on your city.
- Ask what is restored: lawn, driveway, sidewalk, boulevard. London includes restoration in its flat rate.
- Ask about permits and the city’s side: who connects to the main, and who inspects.
What insurance does with a failed line
General Insurance OmbudService (GIO), Water Damage & Insurance: What will my insurance cover? · 2026
GIO's definition of water and sewer lines coverage — what this site calls service line coverage, under one of its several names. Quoted as published, including the missing comma. “On your property” is the phrase that makes the city's own boundary rule matter: where your side of the pipe ends decides how much of a failure this coverage can reach.
Service line coverage is written for exactly this pipe — a leak, break or collapse on your property — up to a stated limit. What it is not is a replacement plan for an old pipe that has not failed. And the water that comes into the basement when a line fails is a separate question: sewer backup, which a standard Canadian policy does not include.
Insurance Bureau of Canada, Water Damage and Flood Protection · 2026
IBC's wording is unambiguous: “Damage caused by the backing up of sewers and drains is typically not covered by a standard policy.” It adds that “optional sewer backup is offered by most insurers” — so the cover exists, it is just not switched on by default.
Why this site has nothing to gain from your answer. We are paid a fixed amount for each enquiry, agreed before it is sent. It does not move with the size of the job, with whether you book anything, or with which company you pick. So there is no version of this page where steering you is worth anything to us — which is also why you will not find a company named, rated or recommended anywhere on this site.
Questions people actually ask
How much does sewer line replacement cost in Canada?
No Canadian average is published. The one municipal price this site found is London's: the City replaces a Private Drain Connection for a 2026 flat rate of $7,250, payable as a lump sum or on property taxes over ten years, including camera inspection, cleaning if needed, the repair method and restoration.
Who pays to replace the sewer line from the house to the street?
It depends on the city. London, Hamilton and Winnipeg make the owner responsible to the main; Ottawa, Calgary, Edmonton, Saskatoon and St. Catharines split the pipe at the property line, with the city responsible beyond it.
Is lining cheaper than replacing a sewer line?
This site has no price comparison. London says lining a Private Drain Connection eliminates the need to dig up the original pipe, and that a collapsed or severely damaged connection may have no option but replacement.
Does home insurance pay to replace a sewer line?
Not as maintenance. Service line coverage, where offered, pays up to a specified limit when a water or sewer line on your property leaks, breaks, tears, ruptures or collapses and causes damage. The resulting water damage is sewer backup, an optional endorsement.
Does the city help pay for a new sewer line?
Sometimes, on conditions. Hamilton may reimburse part of the cost when City-tree roots damaged the private portion and you replace it all. Winnipeg arranges repairs under the street for eligible owner-occupied homes. Saskatoon's by-law ties any cost-sharing to replacing rather than repairing a non-compliant pipe.
How do I know if my sewer line needs replacing?
A camera inspection. London's crews inspect with a sewer camera before choosing the method, and Hamilton says a complete lateral investigation includes a colour CCTV recording of the whole lateral.
