Sewer Lateral Responsibility in Greater Victoria

Sewer lateral responsibility in Greater Victoria is not the same in every municipality. In Oak Bay the owner is responsible all the way to the main. In Saanich the owner pays for the private side and the municipality for the public side, with exceptions. In Victoria and Esquimalt the boundary is at the property line. Always check the bylaw for your address.

Who is responsible for the sewer lateral where I live?

Here is what each municipality's own bylaw or page says, with the source in the list below. Where we could not confirm the wording, the table says to check with the municipality instead of guessing.

What does Oak Bay's bylaw say?

The District of Oak Bay says homeowners are responsible for maintaining storm and sewer laterals from their property to where they connect to the public sanitary sewer main past the property line. Bylaw 3891 governs, with replacement prices in its Schedule A. The page divides it into a private side (house to property line), which is the owner's, and a public side (property line to main), where the owner contacts District Engineering for replacement service. The District recommends a routine camera inspection every one to three years and a camera check before any work, to avoid conflict with gas utilities. Oak Bay engineering is 250-598-3311.

What does Saanich's bylaw say?

Saanich's Sanitary Sewer Bylaw 8792 (the consolidated version includes Amendment Bylaw 9837, 2022) draws the line at the property line and defines two terms:

A sanitary sewer lateral is the sewer piping on private property from the property line to the building. Section 11(a) makes the owner responsible for the cost of servicing, clearing, rodding, removing blockages or tree roots, or maintaining it in any way.
A sanitary sewer connection is the piping on public property from the sewer to the property line. Section 11(b) makes the municipality responsible for the same work on it.
The exception, section 11(c). The owner pays to repair or replace the connection where the problem arises from a condition existing on private property, an improper connection between the connection and the lateral, or a prohibited waste discharged by the owner.

Saanich's guidance for a backup is practical: call a licensed plumber, who must contact BC One Call (1-800-474-6886) before using clearing tools to prevent damage to gas lines. If the plumber finds the blockage on the municipal side, contact Saanich Storm and Wastewater at 250-475-5599 while the plumber stays on site, and call your insurance agent promptly. Note that Saanich's web page also says the homeowner has to determine where the blockage is, regardless of whether it is on private or public property. That is why a plumber's camera finding matters.

What does the City of Victoria's bylaw say?

Victoria's Sanitary Sewer and Stormwater Utilities Bylaw No. 14-071 (consolidated January 22, 2026) divides it differently:

The building sewer is the pipe on the lot. Section 25 makes the owner maintain it in good repair, clear any stoppage, and pay for it.
The service connection is defined as the City-owned pipes connecting the building sewer to the public main. It does not include any part of the building sewer, inspection chamber or cleanout extending more than 0.3 metres from the lot boundary into a City road allowance or right of way.
Section 26. If the plumber reports that the building sewer is clear and the stoppage is in the service connection, the owner must notify the City and request clearance. The City examines it. The owner or occupier pays the actual cost of clearing and repair if the stoppage was due to an act or omission of the owner or to foreign material, including roots from trees on the owner's property, entering the connection.
The bylaw also requires an inspection chamber within 0.3 metres of the property line, and says the City is not responsible for maintaining any part of a building sewer that extends 0.3 metres or more into a public right of way.

What about Esquimalt, View Royal, Langford and Colwood?

Esquimalt's pipe ownership page says the sewer line from the property line to a home is owned and maintained by the property owner, and that municipal sewers include the lateral from the main to the property line. View Royal says occurrences on private property are the property owner's responsibility to identify and remediate, and does not define the boundary on that page, so confirm with the Town. Langford's page says the sewer system is owned and operated by West Shore Environmental Services and that the property owner pays to connect to the main, but does not state who is responsible for the lateral or a blockage; contact WSES (250-478-2187) or the City. We could not read Colwood's page, so check with the City.

What should I do before buying or renovating?

Ask for a camera inspection of the lateral, and find out from the municipality what the bylaw says about your property. In the City of Victoria, a building permit with a declared value over $100,000 on a property with an existing service connection triggers a requirement to have the service connection tested by City staff if it is older than 20 years, not PVC or of unknown material. Read our guide to sewer camera inspections in Victoria for what an inspection shows, and perimeter drain replacement and sump pump installation for the other drainage costs that can arrive with an older property.

What should I do if the sewer is backing up?

Stop using water, call a licensed plumber and have them find where the blockage is. Our emergency repairs service covers backups, and drain clearing vs drain replacement explains the repair options. Bylaws are amended, so verify the current wording with your municipality, and contact us if you want a plumber to inspect your line. See also our drain clearing service.
