Plumbers in Castle Rock, CO

Douglas County's seat on I-25

Castle Rock is a home rule town and the Douglas County seat, named for the butte that rises north of downtown. Incorporated in 1881, it had 73,158 residents at the 2020 Census and keeps growing. Its center is about 26 miles from downtown Denver in a straight line, down Interstate 25. US 85 and Founders Parkway lead to neighborhoods such as The Meadows, and Philip S. Miller Park is a well-known gathering spot.

Well water, plus renewable supplies

Unlike Denver's mountain reservoir system, Castle Rock Water leans on deep groundwater from the Dawson, Denver, Arapahoe and Laramie-Fox Hills aquifers. It adds renewable sources: shallow alluvial wells, Plum Creek diversions, imported WISE water and reuse water. The Plum Creek Water Purification Facility is the main plant, with the Founders, Meadows and Ray Waterman plants adding capacity at peak demand. Castle Rock Water also runs a separate system for Bell Mountain Ranch, and some addresses with a Castle Rock mailing address, such as The Village at Castle Pines, are served by other districts.

The water is disinfected with chloramine. The town's report lists average hardness of 100 ppm with a range of 61 to 182 ppm, and its FAQ puts it at 6.6 to 10.8 grains per gallon. Even so, Castle Rock Water does not recommend water softeners because of the salt they send into wastewater. That makes regular water heater flushing and aerator cleaning a more practical answer to scale. The utility says its distribution service lines are non-lead.

Backflow for irrigation

Castle Rock Water's cross-connection program requires yearly testing for all businesses, nonresidential irrigation systems and certain fire suppression systems, and only testers registered with the town may do it. Homes with underground lawn irrigation need an approved mechanical backflow assembly. Yearly testing is not listed as required for residential irrigation, but the utility recommends periodic testing.

Permits and sewer

The Town of Castle Rock's building department handles building permits and permit status. The details of which plumbing jobs need a permit were not confirmed, so check with the town before replacing a water heater or moving pipes. The sewer provider was not confirmed either; your utility bill shows who handles wastewater for your address. Water leaks in the street go to Castle Rock Water at 720-733-6000, pressing 1 after hours.

Gas safety and what's different here

Castle Rock is a Black Hills Energy town, not an Xcel town. If you smell gas, leave the house first, call 911, then call Black Hills Energy at the emergency number printed on your gas bill. No housing-age figure for Castle Rock was confirmed. Between the well-based supply, the softener guidance and a different gas utility, plumbing here differs from Denver in several ways. Call the number on this page, explain the problem, and you will be connected with an independent plumber serving Castle Rock who sets price and timing with you.
