Frederick's drinking water comes from the Town of Frederick east of I-25 and from Left Hand Water District west of it, with Central Weld County Water District serving part of town. That means most homes have no well pump at all; where a property does have one, a plumber can test it. Call the number on this page to be connected with a local plumber in Frederick.

How to recognize a failing well pump
- The water quits everywhere at the same moment
- The tank's pressure gauge sits at or near zero
- Fast, repeated clicking from the pressure switch
- Spurts of air and uneven flow
- The pump circuit trips
On a home with its own well, each of these points to the pump, the controls or the tank. On piped water, they point somewhere else entirely, which is why it pays to know your supply.
Frederick's water picture
Three entities deliver drinking water inside Frederick. All residents east of I-25 are Town of Frederick customers, Left Hand Water District serves residents west of I-25, and Central Weld County Water District serves part of town. The Town's supply is Colorado-Big Thompson water from Carter Lake plus Town-owned Windy Gap units, treated at Central Weld's Carter Lake Filter Plant and disinfected with chlorine.
None of that involves a household pump. If pressure fades in a Frederick home, the usual culprits are a pressure regulator, a leak somewhere on the owner's side of the meter, or fixtures clogged with debris. Frederick's coal-mining history and today's fast-growing subdivisions mean you'll find a wide range of home ages, and an older house can have older valves and lines.
The fact sheet doesn't record private wells in Frederick. If you have a wellhead on your property, for the house or for irrigation, treat the signs above as real well symptoms. Irrigation tied to drinking water needs care too: Frederick requires reduced pressure (RP) backflow assemblies on irrigation systems.
Factors in the price
- Diagnosing a pressure loss on Town or Left Hand water versus repairing well equipment
- For wells: the failed part, the pump depth and the tank
- Locating and digging up a leak on the house side of the meter
- Regulator replacement
- Any RP backflow assembly needed for irrigation
