Water and sewer in Commerce City
The city does not run its own water system. South Adams County Water and Sanitation District (SACWSD), the largest combined water and sanitation district in Colorado, provides water and sewer for the Commerce City area. A few spots may be on another district, such as Industrial Park Water and Sanitation, so confirm with your bill. Tap water is a blend of SACWSD well water treated at the Klein facility and Denver Water surface water, and wastewater goes to the district's own Williams Monaco plant rather than to Metro Water Recovery.
SACWSD takes emergency calls for main breaks, turning water on or off, sewer main backups and emergency locates at 303-288-2646, during and after business hours. For a sewer backup, the district asks customers to call so it can help figure out whether the blockage is in the public main or the private line, which belongs to the property owner. It also advises removing tree roots near sewer service lines, since roots are a frequent cause of these backups.
District problem or plumber problem?
| What is happening | Who to call |
|---|---|
| Water main break or water gushing in the street | SACWSD, 303-288-2646 |
| Sewage backing up, cause unclear | SACWSD to check the main, plus a plumber for the private line |
| Burst pipe or leaking fixture inside | A plumber |
| Leaking or failed water heater | A plumber |
| Smell of gas | Leave; call 911 and Xcel Energy outside |
Signs you should not wait
- Water spreading across a floor or coming through a ceiling
- Sewage rising in a basement drain or bathtub
- The water heater leaking from the bottom of the tank
- Sudden loss of water while nearby homes still have it
- A frozen pipe that has started to leak as it thaws
Timing and seasonal notes
Winter cold snaps split pipes in garages, crawl spaces and outside walls, and the leak often appears when the pipe thaws later in the day. Root intrusion into sewer lines builds slowly and can show up as a sudden backup any time of year. After-hours calls usually cost more. Commerce City's Building Safety Division lists water heater replacement as work that can need a permit, so call 303-289-3790 to confirm before a replacement. No arrival time is promised.
