Clogged Sewer Lines
If your sewer does back up, please call the City of Longmont Water Utilities at the numbers listed above under "emergency numbers". Plugged sewer lines are most frequently caused by roots, grease accumulation or structural problems.
Business Owners: Check your grease interceptors/traps and sand traps. Make sure they are cleaned on a regular basis and records are kept.
Sewage back up: If sewage backs up into your basement or crawl space only when you run water in your house/business, the problem is most likely to be in your system and you may need to call a plumber to repair it. The homeowner is responsible for clean up or repair, including repairing damage to the street or driveway if necessary.
If sewage is running into your house/business and you haven't been running water, call the Utility Operations emergency number immediately. The City of Longmont will send a crew out to investigate the problem and clean the main, if plugged. If a problem is found in our main, causing damage to your property, a claim should be sent through the City's Risk Management Office at (303) 651-8435.
Your plumbing system: It is a good idea for all property owners and tenants to become familiar with the general layout of your plumbing system - 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.
Preventing clogs: Residents 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 into the trash. Any other greasy leftovers (bones, meat trimmings, etc.) should be thrown into the trash. FREE Fat Trappers are available.
Other household and business wastes: Do not dispose of these wastes into the sanitary or storm drainage system:
Paint thinner and other solvents
Oil-based paints (in any quantity, including clean-up waste)
Pharmaceuticals or Over the Counter Medication
Photographic fixer solutions from a darkroom
Mercury (broken thermometers or other sources)
