Most of Commerce City gets water from the South Adams County Water and Sanitation District, and a leak in the buried line on your property is generally a private repair for a plumber. The district takes main breaks and emergency locates at 303-288-2646. Call the number on this page to be connected with a local plumber in Commerce City.

Local conditions in Commerce City
The city lists the South Adams County Water and Sanitation District (SACWSD) as its water and sewer provider. SACWSD calls itself the largest combined water and sanitation district in Colorado, covering more than 65 square miles. Its water is a blend of district wells, both alluvial and deep Arapahoe formation, and treated surface water bought from Denver Water. A few areas may be on another district, such as Industrial Park Water and Sanitation, so confirm the name on your bill.
SACWSD takes emergency calls for main breaks, water shutoffs and emergency locates at 303-288-2646, during and after business hours. The district hasn't published the exact point where its pipe ends and yours begins, so if water is surfacing near the street or meter, call it first. A leak between the meter and the house is the owner's to fix.
SACWSD inventoried both system-owned and customer-owned service lines and classifies all of them as non-lead, with no galvanized lines requiring replacement. That takes one worry off the table. Commerce City grew from farmland after industry arrived in the late 1920s, so the housing mixes older homes near the original core with newer subdivisions to the north. Building permits run through the City of Commerce City Building Safety Division and its eTRAKiT portal (303-289-3790).
Repair or replace?
| Choice | Good fit | Keep in mind |
|---|---|---|
| Section repair | One break on a line in fair shape | Quick, but the rest of an older line may follow |
| New line by open trench | Clear yard, short run | Direct and visible; lawn needs restoring |
| New line by boring or pulling | Driveways, fences or trees over the route | Smaller excavation; soil and access must allow it |
Signs to watch
- A wet or sunken area along the route from the street
- Low pressure everywhere in the house
- The meter moving with no water in use
- A higher SACWSD bill with no change in habits
Seasonal notes
Winter freezes and rapid temperature swings strain buried joints, and leaks often surface in early spring as the ground thaws. Spring sprinkler startup can also uncover problems. A slow leak can wait for a scheduled visit; water flowing into the yard or the house means closing the main shutoff and getting help the same day.
