Plumbers in Centennial, CO

A young city in Arapahoe County

Centennial was carved out of unincorporated Arapahoe County in 2001, making it one of the newest cities in the metro, and the 2020 Census counted 108,418 residents. Its center is about 15 miles from downtown Denver in a straight line. Interstate 25 splits the city roughly in half, with a business and entertainment core to the west and rolling hills, ravines and trails such as the High Line Canal and Willow Creek corridors to the east. Southglenn, Castlewood, East Arapahoe Road and DeKoevend Park are familiar landmarks.

Which district serves you matters

The city says water and sewer come from several special districts. Its maps list water providers including the Arapahoe County Water and Wastewater Authority, Castlewood, Cherry Creek Village, East Cherry Creek Valley, Havana, Inverness, Southgate, Willows and South-East Englewood. Southgate and Willows both distribute Denver Water's mountain supply; Denver Water's report gives average hardness of about 105 ppm for that water. Sewer districts include Southgate Sanitation, South Arapahoe Sanitation, Castlewood, Havana, East Cherry Creek Valley, the county authority and South Englewood Sanitation District No. 1.

Rules follow the district. In Southgate's area, for example, the owner is responsible for the service line on the house side of the curb stop, owns the meter and handles the meter pit, while the district repairs leaks between the main and the edge of the right-of-way on written request. Southgate's rules also put backflow devices on the owner to maintain and replace. Southgate takes water break and sewer backup calls at 303-779-0261; Willows can be reached at 303-770-8625. If you are unsure which district you have, the name is on your water bill.

Permits from the city

The City of Centennial Building Division requires a permit for any work on plumbing, gas, mechanical or electrical systems. The office is in the Centennial Civic Center at 13133 E. Arapahoe Road, and its number is 303-754-3321. That means a water heater swap, a new gas line or a repiping job all go through the city, not Arapahoe County and not Denver.

Gas service

Xcel Energy is the city's listed gas utility. If you notice a gas odor, leave the house first, then call 911 and Xcel at 1-800-895-2999 from a safe spot outside.

What's different from Denver and how calls work

A Denver address has one answer for water and one for sewer. In Centennial the answer changes from one subdivision to the next, so the district's own rules decide who fixes what. The fact sheet has no housing-age figure for Centennial, so ask the plumber to look at pipe material on the first visit. Call the number on this page, describe the issue and your district if you know it, and you will be connected with an independent plumber serving Centennial who sets price and timing with you.
