The city maintains approximately 120 miles of sewer mains, including the 27-inch force main running from the lift station at 105th Avenue and Irma Drive to the Wastewater Treatment Plant in Weld County, and 10 pump stations. The city acquired the sewer lines in its boundaries in 1979 from Thornton after incorporating in 1969.
Sewer backups happen for a number of reasons. The most common are grease, tree roots, separation at a pipe joint, a foreign object or collapsed pipe due to age and corrosion.
If you experience a sewer backup, you may call 303-451-1289 to report it. The city will check the main sewer line running through the street in front of your house to make sure it's flowing freely. The sewer pipe from your house to where it taps into the main line is called the service lateral, and is the responsibility of the homeowner.
Water that drains slowly may be the first clue that a problem is developing. Preventive maintenance in the form of routine roto-rooting is the best line of defense against more serious problems.
Sewer Main Break
To report a known or possible sewer main break, call 303-451-1289 for immediate assistance. Your help in notifying the city will ensure a prompt response before further damage can occur.
As the city's aging pipes deteriorate, breaks may occur unexpectedly before repairs or replacements are scheduled. These incidents are treated as a very high priority and repairs are made as quickly as possible.
If you experience problems with slow drains or sewer backups, a plumber may send a camera into your sewer service line to determine exactly where the problem is and what might be causing it. A recorded video tape of your line will confirm whether or not extensive repairs are needed.
The homeowner is responsible for the service lateral line, which runs from your home to where it taps into the city's main line. The city will review the video tape at no charge to determine if any portion of the problem may fall within the city's responsibility for repair.
Call 303-280-7803 from 7 a.m. to 3:30 p.m. weekdays for assistance.
The main sewer lines throughout the city are routinely flushed with a high pressure water jet to remove sediment, grease and other debris that might obstruct the flow in the pipe and possibly cause a backup into your home. You may have noticed a large noisy truck on your street from time to time.
The sewer mains are flushed at least once every three years. Some lines are prone to more problems than others, and they are flushed more frequently – some as often as every three months.
