Glendale buys all its water from Denver Water but maintains its own water mains and bills customers itself, so main and billing problems go to Glendale Public Works rather than Denver Water. A leak on the private line to your building is generally a plumbing repair. Call the number on this page to be connected with a local plumber in Glendale.

Glendale's water setup
Glendale is a small Arapahoe County city completely surrounded by Denver along Colorado Boulevard and Cherry Creek, and it's the most densely populated municipality in Colorado. Its water is Denver Water's treated mountain snowmelt, but the city maintains the mains and handles billing. That makes Glendale Public Works, at 303-639-4500, the first call for anything that looks like a main break or a problem at the street.
The city's published material doesn't spell out where its responsibility ends and the owner's begins. Don't assume Denver Water's own customer rules apply, since Glendale owns its mains and runs its own system. In most systems the pipe on the building side of the meter or curb stop is the owner's, so treat a leak between the meter and the building as a private repair and ask Public Works about anything at the meter itself.
Density shapes the job here. Many Glendale properties are apartment and condominium buildings and commercial sites packed close together, with service lines running under parking lots, sidewalks and landscaped strips. A short run can still be complicated if it crosses pavement or sits near other buried utilities. Plumbing permits go through the City of Glendale Building Department, not Arapahoe County or Denver; its main permit application covers plumbing along with most other project types.
Approaches compared
| Approach | Where it fits | Consideration |
|---|---|---|
| Section repair | A single leak on a sound line | Least disruption to pavement |
| Open-cut replacement | Short runs under lawn | Simple, but concrete and asphalt cost more to restore |
| Trenchless replacement | Lines under parking lots or walks | Avoids cutting pavement if soil and utilities allow |
Warning signs
- Water seeping up through pavement joints or a lawn strip
- Low pressure across the whole building
- A meter moving with no water in use
- A higher city water bill without a change in use
Timing notes
Freeze and thaw cycles stress buried joints, and pavement can hide a leak until water finds a seam. Glendale's Building Department asks for inspection requests by 3:30 p.m. the day before and doesn't inspect on Fridays (inspection line 303-639-4605), so plan the work around that when a permit is needed.
