Glendale is its own city inside Denver: it buys all of its water from Denver Water, but the City of Glendale maintains the mains, bills customers and issues plumbing permits. Plumber Denver CO connects callers with independent local plumbers and does no plumbing work itself. Call the number on this page to be connected with a local plumber in Glendale.

Plumbing services in Glendale
A small city surrounded by Denver
Glendale is a home rule city in Arapahoe County, incorporated in 1952, and it is completely surrounded by the City and County of Denver. It sits about 4 miles from downtown Denver along Colorado Boulevard and Cherry Creek, and with 4,613 residents at the 2020 Census it is the most densely populated municipality in Colorado. East Virginia Avenue, East Mississippi Avenue, the Cherry Creek Trail and Infinity Park are all inside or along its borders.
Denver Water supply, Glendale management
The water in a Glendale tap is the same treated mountain snowmelt Denver Water delivers across the metro, drawn from sources such as the upper South Platte, the Blue River and the Fraser River tributaries. Denver Water's report puts average hardness at about 89 ppm. What differs is who you call. The City of Glendale maintains its own mains and sends its own bills, so a main break, a meter question or a billing issue goes to Glendale Public Works at 303-639-4500, not to Denver Water.
Inside the house and out to the property line, repairs are a private plumbing matter just as they would be anywhere else in the metro. A plumber can trace a leak, replace a shutoff or swap a failing pressure regulator; the City handles what lies in the street.
Backflow testing
Glendale tracks annual testing of the backflow prevention assemblies connected to its water system. Its water page also notes that an assembly that fails must be retested within 120 days, so a failed result usually means a repair or rebuild and then a new test. Apartment buildings, businesses and irrigation systems are where these assemblies most often show up.
Permits through the City of Glendale
Plumbing work is permitted by the City of Glendale Building Department, not Denver Community Planning and Development or Arapahoe County. The City's main building permit application covers plumbing along with every other project type except signs. Inspections are scheduled through 303-639-4605, requests are due by 3:30 p.m. the day before, and the City does not inspect on Fridays, which is worth knowing when planning a water heater swap.
Gas safety
Xcel Energy holds Glendale's gas franchise. If you notice a gas smell, get everyone out of the building first, then call 911 or Xcel's gas emergency line at 1-800-895-2999 from a safe spot outside. Once the utility has made the area safe, a plumber can repair or replace gas piping and appliance connections.
