Sewer

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.

Water to Wastewater and Back
After the water is used for whatever purpose, laundry, bathing, or flushing, it is then called wastewater and it passes through one lift station and several pump stations. It then travels nine miles in a force main to the Northglenn Wastewater Treatment Plant in Weld County, where it is treated before being discharged into Big Dry Creek or Bull Canal for agricultural irrigation. Our city’s water starts in the mountains, is treated and made ready for your use, then treated again before returning to the earth, a long journey.


Sewer Backup
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 or report it online.  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.

Sewer Televising
If you experience problems with slow drains or sewer backups, a resident may hire a plumber to send a camera into your sewer service line to determine exactly where the problem is and what might be causing it.  The homeowner is responsible for the service lateral line, which runs from your home to where it taps into the city's main line.   A recorded video tape of your line provided by a plumber will confirm whether or not extensive repairs are needed.

Sewer Flushing

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.

Fats, Oil and Grease (FOG)
Cooking grease can cause big problems for your sanitary sewer system!  Pour grease, oil and fats into a container, let it solidify and throw it away, don’t pour it down the drain. It may be liquid when you pour it, but it will harden and cling to the walls of your pipes eventually clogging your sewer system.  That is an expensive and unpleasant problem to have.

Don't Flush Trouble
Your toilet is NOT a trash can.  Labels on products may claim they are "flushable" but disposable wipes and other products can clog sewer lines. 

It's a Toilet, Not a Trash Can. 
Don't Flush:
Disinfecting Wipes
Baby Wipes
Mop Refills
Towelettes
Paper Towels
Q-Tips
Dental Floss
Sanitary Products
Prophylactics
Medical Syringes
