Sheridan's water system is run by Denver Water under a Total Service contract, so Denver Water's backflow rules apply: commercial, industrial, irrigation and fire line services need approved assemblies tested every year. Sewer comes from Sheridan Sanitation District #1. Call the number on this page to be connected with a local plumber in Sheridan.

What to expect on the call
You'll be connected with an independent local plumber who takes commercial work in Sheridan. Describe the property, the problem and whether water is shut off. If the business can't close during the day, raise scheduling up front. For backflow calls, mention when the assembly was last tested and whether it serves domestic water, irrigation or a fire line, since each has its own requirements.
The plumber can also help sort out permits. We couldn't confirm which office issues plumbing permits for Sheridan, so call the city at 303-762-2200 before starting larger work.
What affects the price
- The number of assemblies and fixtures involved
- Locating a leak on the owner's service line or meter setting
- Fire line assembly work, which requires additional tester certification
- Timing irrigation tests within Denver Water's season
- Permits and off-hours scheduling
Local conditions in Sheridan
Denver Water lists the City of Sheridan as a Total Service distributor, meaning Denver Water owns the system, operates and maintains it and reads and bills each meter directly. Don't confuse the city with the South Sheridan Water and Sanitary Sewer District, a separate distributor. Denver Water's supply is mountain snowmelt from both sides of the Divide, and its 2026 report lists average hardness of about 105 mg/L.
Denver Water's backflow program requires an approved assembly on commercial, industrial, domestic, irrigation and fire line services. Assemblies are tested at installation and every year by an ABPA- or ASSE-certified tester, and fire assemblies also need a tester with a Colorado Fire Suppression System Contractor-Backflow certification. Reports go to Denver Water Cross-Connection Control at 303-628-5969, and irrigation assemblies are tested May through September.
On Denver Water service, the owner owns the service line up to the stop and waste valve and the meter setting, and must protect the meter pit, so service line leaks and freeze protection at the pit are the owner's job. Sewer comes from Sheridan Sanitation District #1 at 4101 South Federal Boulevard, 303-483-3259. The gas utility wasn't verified, so check the gas bill for its emergency number.
