Section 01
The published division of responsibility
EPCOR states that drainage in Edmonton is a shared responsibility: property owners are responsible for maintaining and repairing the sewer lines on their property, while EPCOR's responsibility begins at the property line and runs to the main. Read that sentence carefully, because it defines who pays and who arranges work long before anyone discusses condition.
Then confirm it for your address. Configurations vary with the age of the neighbourhood, the way the parcel was serviced and any later redevelopment, and a general statement of policy is not a statement about one property's connection. Ask the utility to confirm the service configuration for the specific address and keep the written answer in the handover file.
Present the published division as the starting point, then confirm the exact service configuration for the address with the utility.
Section 02
Why the network the parcel sits in matters
EPCOR describes an Edmonton collection network that includes combined, separated and land drainage systems. Which of these serves a parcel affects how sanitary and storm flows are handled, and it is a factual attribute of the location rather than a judgement about it.
For an owner, the practical consequence is that advice heard from a friend in another part of the city may not describe your servicing at all. Establish the servicing for your own parcel with the utility, note it in the file, and let that fact frame any later conversation about drainage improvements.
Section 03
Documented: what you can actually obtain
You can obtain written confirmation from the utility about servicing and the responsibility division. You can obtain the plumbing and drainage permit history held by the City for work at the address, which records what was applied for and which inspections occurred. You can obtain from the seller any invoices, camera reports, repair records, liner or replacement documentation and warranty paperwork for previous drainage work.
Where a backwater valve has been installed, there may be a permit record for the plumbing work and program documentation showing how the installation came about. EPCOR publishes a backwater valve subsidy program; cite it, as this page does, only as evidence that a defined program and process exists — never as a statement about a property's flood risk or protection.
Section 04
Not documented: what the record will never contain
No permit record describes the present internal condition of a buried line, the presence of root intrusion, a bellied section, a partial collapse, offset joints or scale. No record predicts remaining service life or when a blockage will occur. No record establishes that a property will or will not experience a backup, because that depends on events, use and conditions no file can hold.
Nor does the record establish exactly where the line runs across the parcel, which matters if landscaping, a garage, a pool or an addition is contemplated. Locating and condition assessment are field work, not paperwork.
Section 05
What a camera inspection adds, and its limits
A camera inspection by a qualified drainage contractor produces something no file can: recorded footage of the interior of the line on a stated date, usually with distances noted and observations described. Ask for the raw footage as well as the report, ask what length of the run was reached and why it stopped there, and ask the contractor to state explicitly what was not accessible.
Its limit is the date. Footage is a condition observation at a moment, not a warranty, and material can move between the inspection and possession. It also cannot resolve a legal question about responsibility at a boundary; that is confirmed with the utility and, where a dispute arises, with a lawyer.
Section 06
The evidence request list
Request, in writing and dated: utility confirmation of servicing and responsibility for the address; the City's plumbing and drainage permit history for the address; the seller's drainage repair, liner, replacement and maintenance records with invoices; camera inspection reports and footage held by the owner; documentation for any backwater valve installation; and a written statement from the seller of any backup, blockage or repair event they are aware of.
Then commission your own camera inspection if the line has not been examined recently. Keep every item with its date and its author, because a drainage history is only useful when a later reader can see when each observation was made.
Section 07
Escalation: who resolves what remains
A qualified drainage contractor resolves condition, location and repair options. The utility resolves servicing questions and its own portion of the responsibility division. A plumber licensed for the work, under the appropriate City permit, performs and has inspected any alteration on the property side.
A lawyer resolves responsibility disputes, easements affecting the run of a line, and any claim arising from damage. An insurer answers coverage questions, which this page does not and cannot. Nothing here is an engineering, legal or insurance opinion about a specific property.
This guide describes records and processes. It makes no claim about any property's drainage condition or risk.
