Who Owns the Sewer Service Line?
The sewer service line is owned and maintained by the property owner. Sewer service is defined as the length of the pipe between the house/business and the sewer main line, which is usually located in the street, easement, or alley.
Reporting a Problem
If you are experiencing sluggish drains or a sewer backup in your house or business, there could be a blockage in your service line or in the main sewer line. The City can check this to determine where the problem may be occurring and what action needs to be taken. Contact Water Utilities Monday through Friday, 8 am – 5 pm. After hours, please call Longmont Police Dispatch, and they will notify a utility technician to respond to your call.
- The nature of the problem, such as sewer odor, sewer backing up, slow running drains, etc.
- Your Name
- Your Address
- Your Phone Number
The City of Longmont will send a crew out to investigate the problem and clean the main sewer line, if plugged. If a problem is found in our main line causing damage to your property through your service line, a claim should be sent through the City's Risk Management Office at (303) 651-8435.
If you believe your sewer line is clogged or sewage backs up into your basement or crawl space only when you run water in your home or business, the problem is most likely in your service line system, and you may need to call a plumber to repair it. Plugged sewer lines are most frequently caused by tree roots, grease accumulation, or structural problems. Property owners are responsible for clean up and repair for problems originating in the service line system, including repairing damage to the street or driveway, if necessary.
Preventing Sewer Line Problems
Property owners can aid in preventing clogged sewer lines by not putting grease and greasy food scraps down the sink or garbage disposal. Grease and meat drippings should be collected in a disposal container and thrown in the trash. Any other greasy leftovers (such as bones, meat trimming, etc.) should be thrown into the trash.
FREE Fat Trappers are available. Fat Trappers are used to collect fry pan grease for disposal to trash.
Never dispose of the following in down your drains or toilets:
- Motor oil
- Paint thinner and other solvents
- Oil-based paints (in any quantity, including clean-up waste)
- Latex-based paints
- Pesticides, Herbicides
- Pharmaceuticals or Over the Counter Medication

Property owners and tenants should become familiar with the general layout of their plumbing systems, and especially the location of your sewer "clean out" outlet. The outlet cover is usually located in the yard and allows easy access to the more distant stretches of the private sewer line so blockages may be removed. A plumber can help locate sewer cleanouts, if you have any.
Commercial property owners should check their grease interceptors/traps and sand traps. Make sure they are cleaned on a regular basis and that records of the inspections are kept.
