The City and County of Broomfield runs the water system, blending its own treated Colorado-Big Thompson water with water bought from Denver Water, and backflow test reports are filed through its contractor, Backflow Solutions, Inc. Every water heater and sewer line repair needs a Building Division permit. Call the number on this page to be connected with a local plumber in Broomfield.

Signs a Broomfield business should call a plumber
- A reminder from BSI that a backflow test report hasn't been filed
- Floor sinks or kitchen drains that slow down between cleanings
- A water heater that leaks at the base or can't keep up with demand
- Urinals and toilets that keep running after a flush
- Low pressure on upper floors or at the far end of the building
- A sewer smell near cleanouts or in a basement mechanical room
Water, permits and testing in Broomfield
Broomfield treats Colorado and Fraser River water delivered through Northern Water's Colorado-Big Thompson Project, by way of Carter Lake and a 33-mile pipeline to Matthew D. Glasser Reservoir, and also buys treated water from Denver Water. The two supplies mix in the pipes. The city disinfects with chloramines, adds sodium carbonate for corrosion control and reports hardness from 24 to 140 ppm, which it describes as soft to moderate. Businesses with aquariums or lab water systems should account for the chloramine.
The Building Division is strict about permits. Every water heater, including a like-for-like swap, needs one, and switching from a tank to tankless requires a gas pipe plan. Sewer line repairs need a permit too. For a restaurant replacing a heater over a weekend or a property manager fixing a lateral, that means building permit time into the schedule.
Cross-connection control runs through Backflow Solutions, Inc. Testers must hold a current backflow license and an annual gauge calibration, and they file reports on BSI Online. Gas service in Broomfield is Xcel Energy.
What changes the cost
- The size of the system and how many fixtures or tenants are affected
- Whether a camera inspection or leak search comes first
- Gas piping changes for a tankless conversion
- Off-hours work so the business can stay open
- Permit review and inspections on heaters and sewer repairs
