Sewer Backup in Edmonton? Here’s What to Do Immediately (And How to Prevent It)
This guide will walk you through what to do if you’re experiencing a sewer backup in Edmonton, what causes it, how to prevent it, and why calling a local professional like Instarooter can save you thousands in cleanup and repairs.
What Is a Sewer Backup?
A sewer backup occurs when water or sewage from the main municipal sewer line flows in the reverse direction — up through your home’s drains, floor drain, or toilets — instead of flowing away as it should. When that happens, dirty water and waste can enter your basement or lower-level rooms, creating a dangerous and costly mess.
Common Causes of Sewer Backups in Edmonton
Tree root intrusion into sewer pipes (especially in older neighborhoods like Highlands, Westmount, and Parkallen)
Clogged or collapsed sewer lines due to grease, debris, or pipe failure
Heavy rainfall or snowmelt overloading the city’s sewer system
Lack of a backwater valve, which helps prevent reverse flow into your home
Old clay or cast iron pipes, which are more prone to cracking and joint failure
What to Do Immediately If You Suspect a Sewer Backup
1. Stop using all water in the home – This includes toilets, sinks, showers, washing machines, and dishwashers.
2. Don’t try to clean it yourself – Sewer water contains harmful bacteria and contaminants.
3. Avoid contact with affected areas – Especially if there’s visible sewage in the basement.
4. Call Instarooter immediately at (587) 988-7387 – We offer emergency sewer backup service in Edmonton and surrounding areas.
Our licensed technicians will quickly inspect your system, identify the source of the problem, and start the cleaning and repair process right away.
How to Prevent a Sewer Backup in the Future
1. Install a Backwater Valve
This simple device prevents sewage from re-entering your home when the main line is overloaded. It’s highly recommended by the City of Edmonton and often required in new construction.
2. Schedule Regular Sewer Camera Inspections
A routine camera inspection helps identify early signs of root intrusion, cracks, or buildup — before they cause a backup.
3. Avoid Flushing Grease, Wipes, or Hygiene Products
Only toilet paper should go down your toilet. Everything else — even if labeled “flushable” — can clog your sewer line.
4. Get Tree Roots Removed
If you have large trees near your sewer line, root intrusion is likely. Instarooter provides safe, non-invasive root removal services in Edmonton.
5. Invest in Professional Drain Cleaning
Don’t rely on chemical drain cleaners. Our hydro jetting service clears debris and buildup the right way — safely and completely.
6. Check Your Window Wells and Sump Pump
Not all basement water comes from the sewer line. Blocked window well drains and failed sump pumps cause just as many wet basements in Edmonton — especially during spring melt.
Who Is Responsible for a Sewer Backup — You or the City?
This one surprises a lot of Edmonton homeowners. The City of Edmonton maintains the municipal sewer main buried under city property. But the pipe carrying wastewater from your house out to the property line — the sewer lateral — belongs to you. If the problem sits on your side of that line, repairing it is your responsibility, not the city’s.
That’s exactly why a camera inspection matters so much: it establishes where the blockage or damage actually is, which determines who pays for it.
Does Home Insurance Cover Sewer Backup in Alberta?
Usually not by default. Most standard Canadian home insurance policies exclude sewer backup — it’s typically sold as a separate add-on, an endorsement or rider you have to ask for. And critically, you can’t add the coverage after a backup has already happened and then file a claim on it.
If you’re not sure whether you have it, call your broker and ask now, before you need it. Some insurers also offer better rates when a backwater valve is installed — and a few require one — which is worth asking about, since it protects your home either way.
Coverage decisions are always made by your insurer, not by us. What we can do is document exactly what we find with camera footage and a written report — which is the kind of evidence a claim needs.

Sewer Backup FAQs — Edmonton Homeowners Ask Us These
How do I know if the problem is my sewer line or the city’s main?
The clearest sign is whether your neighbours are affected too. If several homes on your block are backing up at once, the issue is likely on the city’s side. If it’s only your house — especially if it’s happening repeatedly — the blockage is almost certainly in your own sewer lateral. A camera inspection settles it definitively, and that footage is what you’ll need if you end up dealing with the city or your insurer.
How long does it take to clear a sewer backup?
Most straightforward blockages are cleared the same day, often within a couple of hours of arriving. Where it takes longer is when the camera reveals a collapsed pipe or serious root intrusion, because that shifts from a cleaning job to a repair job. We’ll tell you which one you’re dealing with before we start, not after.
Can I just use a chemical drain cleaner?
No — and with a true sewer backup it can make things worse. Store-bought chemicals aren’t strong enough to clear a main line blockage, they sit in the pipe, and they corrode older clay and cast iron lines, which are exactly the pipes most Edmonton backups happen in. They also create a hazard for whoever works on the line afterward.
Is sewage water in my basement actually dangerous?
Yes. Sewage carries bacteria, viruses, and parasites, and the health risk is the reason we tell people not to clean it up themselves. Keep children and pets out of the area, don’t touch anything that’s been in contact with it, and if the smell is strong, ventilate the space and stay out of it until it’s handled properly.
Will a backwater valve stop this from happening again?
It stops the most common scenario — sewage flowing backwards into your home when the city main is overloaded during heavy rain or snowmelt. What it won’t fix is a blockage originating inside your own line, like root intrusion or a collapsed section. For most Edmonton homes, the right combination is a backwater valve plus periodic inspection of the lateral.
Do you come out at night and on weekends?
Yes. Sewer backups don’t wait for business hours, and neither do we. Call (587) 988-7387 any time — we serve Edmonton, St. Albert, Sherwood Park, Beaumont, Leduc, and surrounding communities.
