Northglenn treats its own drinking water and runs its own wastewater plant, and homeowners pay for the water line from the meter to the house and the sewer lateral to the city main. Much of the housing dates from the late 1950s and 1960s.

A planned community from 1959
Northglenn began in 1959 as Perl-Mack's planned community, which Life magazine once called the most perfectly planned community in America, and it incorporated as a city in 1969. It is in Adams County with a small part in Weld, about 10 miles from downtown Denver in a straight line, and the 2020 Census counted 38,131 residents. Interstate 25, 120th Avenue, Washington Street and Community Center Drive frame the city, with E.B. Rains Jr. Memorial Park at Webster Lake, Northglenn Marketplace and the 112th Avenue N Line station nearby.
Older houses, private laterals
Much of Northglenn's housing comes from the original Perl-Mack build-out of the late 1950s and 1960s, with newer infill such as Karl's Farm. Homes of that age can have original galvanized supply lines, cast iron drains and clay sewer laterals, so slow drains, root intrusion and low pressure are worth a closer look rather than a quick fix. The city is clear about responsibility: homeowners pay for leaks between the water meter and the house and own the sewer lateral from the house to the city main. Residents are asked not to operate the shutoff in the meter pit themselves.
A city that treats its own water and sewage
Northglenn's water comes from Clear Creek watershed snowmelt and rain carried by the Berthoud Pass Ditch, Croke Canal and Church Ditch to Standley Lake, where it is stored alongside Thornton's and Westminster's water. The city treats it at its own plant on West 112th Avenue and disinfects with chlorine, not chloramine. It keeps a service line material inventory that residents can request from Public Works.
Sewage flows through about 120 miles of mains and 10 lift stations to the city's own wastewater treatment facility in Weld County, roughly nine miles north, rather than to Metro Water Recovery. For water or sewer line issues, call 303.280.7803, or 303.451.1289 after hours.
Permits and backflow
The Building Division, staffed through SAFEbuilt, requires permits for water heater installation or replacement, plumbing modifications, outside water or sewer line repair or replacement, and gas lines. Its number is 303.450.8745. The city's backflow program covers commercial, industrial and non-single-family residential properties such as townhomes and apartments, with yearly tests by an ABPA- or ASSE-certified tester.
Gas safety and calling
No gas utility for Northglenn was confirmed; check your gas bill for the company and its emergency number. If you smell gas, leave the house first, then call 911 and your gas utility from outside. Compared with Denver, Northglenn has a different water source, disinfectant, treatment plants and permit office. When you call the number here, mention the age of the house, and you will be connected with an independent plumber serving Northglenn who sets the price with you.
