Wastewater

Our Wastewater division maintains more than 1,200 miles of sanitary sewer underground lines and pipes.Annually, we clean 662 miles or 3.5 million feet of pipes annually and we CCTV inspect 95 miles or 500,000 feet of pipe.

Wastewater refers to any water that has become contaminated by human influence and is broken into two groups: sewage and stormwater, which are managed through separate systems in Aurora.

The city of Aurora offers a free service to Aurora residents. If you are experiencing backups or have questions/concerns about your later sewer service line, you can submit video footage of your pipe to the above email address. A Wastewater staff member will review the video and consult on suggestions, next steps, potential resolutions, etc. This serves as a second opinion in instances when homeowners are uncertain on repairs or maintenance of their sewer line. A video scope of your service line can be attained from a plumber or other vendor – customers usually receive a copy of the video in the form of a YouTube link or email attachment which can be easily forwarded to the city of Aurora via email.  

Sewage and sanitary sewer system 

Sewage comes from homes and businesses, commercial properties and public institutions and is the wastewater generated from bathrooms and kitchens. Sewage runs through the sanitary sewer system and is treated in sewage treatment facilities through a variety of biological and chemical processes and rendered safe before it's returned to the environment.

A sewer system is a network of pipes located within your home, behind walls and under floors that carry all your home’s wastewater to an underground lateral line. This lateral line connects your home to the city’s main sewer system. All pipes within your home, including the main lateral line, are your drainage system and your responsibility to maintainAurora Water maintains only the city main lines located in the public right of way such as streets, alleys and easements.

If you ever face a problem with your home's sewer system, it could be a result of a clogged drain in a specific area of your house. However, the main lateral line that connects your house to the city's sewer system can also sag, leak or rupture. In such a scenario, you may notice a backup of water in the lowest level of your house, such as a floor drain, lower-level shower, tub or toilet. It's important to note that this issue is still a part of your system, and it's your responsibility to fix it.

One of the most common misconceptions regarding wastewater infrastructure is that the utility provider will make the repairs and pay for the associated damages. However, it’s the property owner’s responsibility to maintain and repair the wastewater (sanitary sewer) service line that runs from their home or building to the city’s sewer mains in the alley or right of way, as well any resulting damages.

Typical maintenance and repair issues include:

    • Blockage or backup – commonly caused by tree roots, fats, oils and grease (FOGs), baby wipes or other paper products. Learn more about common causes and how to prevent blockages and backups.

    • Infiltration – cracks in the pipe, allowing groundwater into the system.

Property owners are responsible for:

    • Maintenance and repairs to the wastewater/sewer service line from the sewer tap to the service address, as well as plumbing lines and services inside the building

    • Connection to the city main that includes the tee or saddle

    •  Associated property damage

    • Locating the sewer service line/tap (call 811)

Aurora Water is responsible for:

    • Maintenance and repairs to the wastewater/sewer main and manholes, as well as associated street and/or property damage

    • Responding to customer calls regarding sewer blockages by cleaning and/or inspecting the main sewer line

    • Locating the sewer main

  • Reporting a Blockage or Backup 

    If you have a blockage or backup, call a plumber so repairs can be made as quickly as possible, as well as Aurora Water 303-326-8645 to report the issue and your insurance company for further direction. 

What we do

What to expect when we're inspecting vs cleaning 

During cleaning operations, you may see a large Vac-Con combination jet truck alongside a supporting pickup truck on your street with surrounding cones and strobe lights. During jet truck operations, the engine can rev loud as part of normal operations. It is normal and expected to hear sounds inside of your home while the jet truck flushes the city sewer main out in the street, especially near plumbing fixtures such as toilets, floor drains and sinks. While the jet nozzle action propels up the city sewer main in the street, the nozzle’s water pressure can create a vacuum or back pressure effect within the city main and connected residential lateral pipes. Sometimes, this vacuum can suck water from a home’s P-Traps away from the home. Once jet operation is complete and normal air pressure is restored in the sewer, that air/water returns toward the home and you may hear and see a gurgling and bubbling effect in your toilets or sinks. It is important to note that these or normal events, and no water, sewage, or gases from the city main will be flushed or pushed into your home. Always keep P-Traps in your home full of water to prevent sewer gases from entering your home. Do this by using all toilets, sinks, showers in your home and occasionally filling all floor drains with water as unused fixtures will dry out over time.  

During inspecting operations, you may see a large van with surrounding cones and strobe lights parked in a particular spot for long periods of time. Much like cleaning operations, the inspection van must be positioned near manholes for access. The operator will do their best to safely stay out of the way, but some traffic interference is normal. Aside from this, the inspections process does not typically cause any disturbances – it is quiet and you may not know anything is occurring if you don’t see the van on the street.
