In Parker, water and sewer usually come from the Parker Water and Sanitation District, a special district separate from the Town of Parker, though some neighborhoods are outside it. Water heater and furnace replacements need a Town of Parker building permit.

Plumbing services in Parker
Southeast of Denver along Cherry Creek
Parker is a Douglas County home rule municipality that still calls itself a town. It incorporated in 1981 and counted 58,512 residents at the 2020 Census. Its center is about 21 miles from downtown Denver in a straight line, set along Cherry Creek and Parker Road (State Highway 83). Mainstreet and the PACE arts center form the town center, and the unincorporated communities of The Pinery to the south and Stonegate to the west border the town.
A district, not the town, runs the water
Parker Water and Sanitation District (PWSD) is unaffiliated with the Town of Parker and serves the town and nearby areas. Not every Parker address is in it: the Parker Chronicle reports that Stroh and Hess Ranch residents are outside its boundaries, and The Pinery has its own Pinery Water and Wastewater District for both water and sewer. Your bill tells you which one you have.
PWSD blends three kinds of supply. Denver Basin aquifer wells are treated for iron and manganese. Cherry Creek and Newlin Gulch water is stored in Rueter-Hess Reservoir and filtered at the Rueter-Hess Water Purification Facility, the first in the country to use large-scale ceramic membrane filtration for drinking water. WISE partnership water is treated by Aurora. The district disinfects with chloramine and reports average hardness of 108 ppm, ranging from 34 to 206 ppm, which matters when choosing a water heater or softener. PWSD notes that red or discolored water can come from naturally occurring iron and manganese in its wells. Wastewater goes to PWSD's North Water Reclamation Facility, which discharges to Cherry Creek.
Permits and backflow
The Town of Parker Building Division handles permits and inspections inside town limits, and furnace replacements, water heater replacements and plumbing alterations all need permits. Applications go through eTRAKiT, and the division's number is 303-841-0353. Unincorporated areas such as The Pinery and Stonegate go to the Douglas County Building Division instead. PWSD runs a state-required cross-connection program, accepts test reports only from ABPA- or ASSE-certified testers with calibrated kits, and requires more advanced devices for industrial and commercial operations. Its office line is 303-841-4627.
Gas safety
No gas utility for Parker was confirmed, so look at your gas bill for the company name and emergency number. If you smell gas, leave the house first, then call 911 and your gas utility from outside.
Different from Denver, and what to expect
Denver's supply is Denver Water surface water, and permits come from Community Planning and Development. Parker mixes groundwater with reservoir water, splits utilities between districts, and uses either the town or the county for permits depending on the address. No housing-age figure for Parker was confirmed here. Call the number on this page and describe the problem, including any discolored water, and you will be connected with an independent plumber working in Parker who agrees on cost with you.
