The City of Northglenn treats and distributes its own water from the Clear Creek watershed, so Northglenn homes are on city water, not private wells. When pressure drops, the cause is usually on the owner's side of the meter, and a plumber can find it. Call the number on this page to be connected with a local plumber in Northglenn.

Where does Northglenn's water come from?
Northglenn treats its own water at the Water Treatment Facility on West 112th Avenue. The source is Clear Creek watershed snowmelt and rain carried by the Berthoud Pass Ditch, the Croke Canal and the Church Ditch to Standley Lake, where it is stored alongside Thornton's and Westminster's water. It's disinfected with chlorine rather than chloramine. The city also runs its own wastewater plant in Weld County instead of sending sewage to Metro Water Recovery. With the whole system in city hands, no household pump is involved, and a homeowner's concerns start at the meter.
Why would an older Northglenn house lose pressure?
Northglenn began in 1959 as Perl-Mack's planned community, and much of its housing dates from that original build-out in the late 1950s and 1960s. Homes that age can have galvanized supply lines that have narrowed inside, valves that stick partly closed and regulators that no longer hold a steady setting. The city reports average hardness of about 120 mg/L, which is moderate, from 2019 sampling, so some mineral buildup in aerators and cartridges is possible too. A plumber can check pressure at the hose bib and trace the drop room by room.
Who pays to fix a leak in my yard?
You do, if it's between the meter and the house. Northglenn homeowners pay for leaks on that stretch and own the sewer lateral to the city main. The city also requires a permit for outside water or sewer line replacement or repair, as well as for plumbing modifications. A wet spot in the lawn, a sinking patch near the sidewalk or a jump in your water bill can all point to a service line leak.
A local note
For water or sewer line issues, call 303.280.7803, or 303.451.1289 after hours. The Building Division, with services provided by SAFEbuilt, handles permits at 303.450.8745 and inspection requests at 303.450.8748.
Before calling, check whether the drop is at every faucet or only some, and whether hot and cold are both affected. Look at any piping you can see near the water heater or the main shutoff; old gray threaded pipe is a strong hint that galvanized lines are part of the problem.
