The short answer
Common Causes
A sewer-like odor in your yard often comes from a cracked or broken sewer pipe. Tree roots can invade and crush pipes, or shifting soil can cause a joint to separate. When sewage seeps into the ground, it creates that distinctive smell.
Another possibility is a blocked or improperly vented drain pipe. If the vent stack on your roof is clogged, sewer gases can build up and escape through the soil. A failing septic system, if you have one, can also produce a similar odor.
- Tree root intrusion into underground pipes
- A cracked or collapsed sewer line
- Clogged or frozen vent pipe
- Failing septic system or leach field
- Improperly sealed pipe joints
- A broken cleanout cap or missing cover
How to Check
Walk around your yard and look for unusually green or wet patches of grass, which can indicate a leak. Also check for standing water, soft spots, or a strong odor near the sewer cleanout. The smell may be stronger after rain or when the ground is damp.
If you have a septic system, check the area around the tank and drain field for odors or wet soil. For a sewer line, you can pour a bucket of water down a drain and listen for gurgling outside, which might suggest a blockage. If you suspect a leak, avoid digging near the area until a professional inspects it.
When to Call a Pro
If you find a leak or cannot locate the source, contact a plumber or a sewer line specialist. They have the tools to inspect pipes with cameras and pinpoint the problem. For water damage cleanup after a sewer leak, local water damage pros can handle the drying and sanitizing.
Do not ignore a sewer smell. Leaking sewage can contaminate soil and pose a health risk. A professional can also help you determine if your sewer line needs repair or replacement. They can also check for related water damage in your home's foundation or basement.
Prevent Future Odors
To reduce the chance of future smells, keep tree roots away from your sewer line. You can plant trees at a safe distance or install root barriers. Have your plumbing inspected periodically, especially if you have older pipes.
Also, be mindful of what goes down your drains. Grease, wipes, and other items can clog pipes and cause pressure to build up. If you have a septic system, have it pumped regularly. If you live in Rogers, keep a map of your sewer line and cleanout locations handy.
Dealing with Water Damage
A sewer leak often leads to water damage in your yard and possibly your home. If water seeps into your basement or crawl space, you may need water extraction and structural drying. The pros can remove standing water and dry affected areas to prevent mold.
After the pipe is repaired, the pros can also help with any indoor cleanup, such as removing damaged drywall or flooring. They can also perform a moisture inspection to ensure everything is dry. If the leak was severe, consider a full water damage inspection to catch hidden issues.
- Emergency water extraction for standing water
- Structural drying and dehumidification
- Moisture mapping to detect hidden dampness
- Removal of water-damaged flooring or drywall
- Inspection for mold growth and damage

Is a sewer smell in the yard dangerous?
It can be. Sewer gas contains methane and hydrogen sulfide, which can be harmful in high concentrations. The bacteria in sewage can also contaminate soil. If you feel unwell, see a doctor. Avoid prolonged exposure and call a professional to locate the source.
Can a clogged drain cause the smell?
Yes. A clogged drain or vent pipe can cause sewer gases to back up and escape through the soil. If you have a slow drain or gurgling sounds, a blockage might be the cause. A plumber can clear the clog and fix the vent.
Will my insurance cover sewer line damage?
Policies vary, and your insurer decides what is covered. Some policies cover sewer line repairs, while others exclude them. Check your policy and ask your insurance company about coverage for water damage and pipe leaks. Document the damage with photos.
