Calgary Service Line Lookup: read the City's record for your sewer connection

01 /What does the Calgary Service Line Lookup do?

The lookup finds the City of Calgary's record for the sanitary service line that serves one address. It sends a query from your browser to the City's open data portal (data.calgary.ca, dataset xesp-3jc3, *Public Sanitary Service Lines*) and shows what comes back. The dataset is maintained by the City's Water Services business unit, which lists its update frequency as monthly. The 367,397-record reference total belongs to this site's September 24, 2026 atlas snapshot, not a count of the live response.

A sanitary service line is the pipe that carries wastewater from a house to the sewer main in the street or lane. The City's dataset description splits it into two parts, and this split drives everything the tool shows. In the City's published words: from the sanitary main to the property line, “this part of the pipe is owned and maintained by The City of Calgary”; from the property line to your house, “this part of the pipe is owned and maintained by the homeowner.” The dataset records only the first part.

Nothing about your search is kept by this site. The query goes straight to the City's public service, the result is drawn on the page, and closing the tab discards it. You do not need an account, and the tool does not ask for your name or contact details.

02 /How do you enter an address so the City's data recognises it?

Type the house number in the first box and the street name, street type and quadrant in the second. For example, enter “60” and “Crestbrook View SW”. The tool normalizes common street types and the quadrant into the abbreviations the City uses in its records before it sends the query.

Other common street types are shortened the same way. The quadrant matters more than people expect: Calgary reuses street names across quadrants, so “1 Street” exists in several of them and the quadrant is the only thing that tells the records apart. If you are unsure of your quadrant, it appears on your property tax notice and on most mail addressed to the house.

03 /What does a result show?

A successful search returns the public-side record for that address. Each field comes directly from the City's dataset; the tool adds a plain-language reading of the material code.

Below the record the tool adds context from the citywide atlas that this site built from the same dataset: how common that material is across the September 24, 2026 snapshot's 367,397 lines and the era in which it typically appears. The reference figures below are the ones behind that context. A fresh address record and these dated contextual figures have different update dates.

04 /How does the tool decide what to tell you?

The advice line follows three fixed rules keyed to the material code. The rules are deliberately short, because the City's record cannot tell anyone the condition of a pipe, only what it was made of and when it went in.

Two cautions apply to every result. First, the rule reads the City-side code only; it has no information about your side of the property line. Second, a PVC City side on an older house is common after redevelopment, repairs or City work, and it says nothing reliable about the pipe under your yard or basement floor.

05 /Why might the lookup return no result?

When nothing matches, the tool suggests checking the spelling and the quadrant. Those two cause most misses. It also explains that large commercial and multi-family services are not in the City's data, so an apartment building, a large condominium complex or a commercial property may simply not appear.

• Street type or spelling: try the full word (Avenue, Crescent, Close) and let the tool abbreviate it, or check how the street is written on a City notice.
• Quadrant: confirm SW, NW, NE or SE; the same street name often exists in two quadrants.
• House number: use the civic number of the building, not a suite or unit number.
• Building type: large commercial and multi-family service lines are excluded from the dataset by design.
• Brand-new lots: a recently serviced lot may not appear until the City's monthly refresh adds it.

If you are confident the address is right and it is a house, duplex or triplex, the gap may be in the record itself. The City's dataset description invites anyone who believes the pipe material shown is wrong or missing to contact 311, and the same route applies to a missing record.

06 /What are the limits of the City's record?

The record is a City asset inventory, not an inspection. It is useful for knowing what the City installed or renewed and roughly when; it is not evidence of condition, grade, roots or blockages. Treat each field with the right level of confidence.

• Material codes: PVC, CI, CIPP, HDPE, PEX, PE, DI and CON are standard abbreviations. TIL, TP, PLA and OTHER are not defined in the City's metadata. TIL is generally read as clay tile; this site does not guess what TP means.
• Dates: the installed date is the date on the City's record. Pre-1950 lines are mostly coded OTHER, and a CIPP date is usually the relining year rather than the original install year.
• Length: the public-side length averages about 8 m citywide. Your private side, from the property line to the house, is a separate length the City does not record.
• Changes: the City notes that its data changes with parcel redevelopment and City repair or maintenance activities.
• Depth: the dataset has no depth field. A locate during a camera inspection is the practical way to estimate depth on your property.

07 /What should you do with the result?

1. Note the City-side code and year

   Write down the material, the installed year and the public-side length. They help any contractor read your camera video, because a material change on the video often lines up with the property line.

2. Compare with your community

   Open the Community Sewer Atlas to see whether your record is typical for your community or an outlier, for example a PVC record in a community that is 90% clay tile.

3. Inspect the private side if the code is older

   For TIL, CI, TP or OTHER results, a camera inspection of your own side is the next step. It shows the material on your side, its joints and any roots, sags or cracks, with distances from the access point.

4. Report errors or City-side defects through 311

   If the record is wrong, or a camera shows a problem at or beyond the property line, contact 311 with the address, the video and the distances.

5. Get options if your side needs work

   When a camera shows defects on your side, request quotes from contractors who can scope and price the work.

Cost questions follow naturally from the record. The Calgary sewer line costs page explains planning ranges by era, side of the property line and length.
