Plumber Denver CO is a free referral line, not a plumbing company; call the number on this page to be connected with a local plumber in Ken Caryl.

Plumbing services in Ken Caryl
A foothills valley in Jefferson County
Ken Caryl is an unincorporated community and census-designated place in Jefferson County, about 13 miles from downtown Denver in a straight line, with Littleton as the nearest larger city. The 2020 Census counted 33,811 residents. It sits in a valley shaped by its ranch history, framed by the hogback, Tincup Mountain and Beacon Hill, with about 6,000 acres dedicated to Jefferson County Open Space. The Manor House, the Bradford/Perley House, Colorow's Cave and West Centennial Road are local landmarks.
Ken-Caryl Ranch Water and Sanitation District
The district provides water and wastewater service to more than 12,000 people across about 14 square miles of Ken-Caryl Ranch, with over 100 miles of water and sewer lines, and it works with Denver Water as part of an integrated system. The district's water quality report link points to Denver Water's reports. Because the census area is larger than the district's stated service population, some Ken Caryl addresses may be on a different district; your bill shows which.
The district's rules put more on the homeowner than many metro utilities do. The customer is responsible for maintaining and repairing the water service line, owns and maintains the curb stop, and owns the meter, which the district maintains. The sewer service line is also the customer's to maintain. A leak anywhere from the main connection to the house, or a stuck curb stop, is therefore usually a private repair. The district offers a Sewer Line Consultation request form, and its office and emergency number is (303) 979-7424.

Backflow and gas
The district requires backflow devices on fire lines, commercial water lines and multi-family residential properties, tested yearly by an ABPA- or ASSE-certified tester; the district does not do the testing. The Ken-Caryl Ranch Master Association lists Xcel Energy for natural gas in both the Plains and the Valley. If you smell gas, leave the house, then call 911 and Xcel at 1-800-895-2999 from outside.
How Ken Caryl differs from Denver

No housing-age figure for Ken Caryl was confirmed.
