Fort Lupton requires every connection to the city water system to have an approved backflow device, tested before use and every year after, with results filed through Aqua Backflow. The city owns the line to the meter pit or curb box, and owners handle the rest. Call the number on this page to be connected with a local plumber in Fort Lupton.

What happens when you call
The number on this page connects you with an independent local plumber who handles commercial jobs in Fort Lupton. Describe the business, what's failing and whether water is still on. If you need work done before opening or after closing, say so at the start. Have any Aqua Backflow notice nearby if the call involves a backflow device.
The plumber will tell you about permits. Fort Lupton lists water heater replacement among work that needs a building permit, filed through the Community Core portal. Replacing a water or sewer service line on private property needs a separate Public Works sewer or water permit, with a site plan showing the replacement length.
Cost factors
- The number of fixtures and the size of the building
- Backflow device repairs or replacements to pass the annual test
- Excavating the owner's water line or sewer connection
- Two separate permits when a service line is replaced
- After-hours scheduling
Fort Lupton's rules and conditions
The city's Public Works Department runs water mains, hydrants and service lines, bills monthly and operates its own wastewater treatment plant. The split is clear: the city is responsible from the main to the meter pit or curb box, whichever is closer to the main, and owners are responsible for leaks between the meter and the building. The city maintains sewer mains, and owners maintain the sewer connection from the building to the main. Public Works is at 303-857-6694 during business hours and 303-994-3540 after hours and on weekends. The city keeps a service line material inventory with an online map.
The Cross Connection Control Program is broad. Every connection must be protected by an approved backflow device, including lawn irrigation, and devices must be inspected and tested by a certified cross-connection control technician before use and every year after. Results go to Aqua Backflow through TrackMyBackflow.com. Noncompliance can mean disconnection, fines or both, a serious risk for a business.
The city also publishes frozen-pipe guidance: drip cold water on exposed lines, open sink cabinets and keep heat at 55 F or higher when a building is empty. The gas utility for addresses inside city limits wasn't confirmed, so check the gas bill for the emergency number.
Checklist before the visit
- Know where the main shutoff and meter pit are
- Find your last backflow test result
- Clear access to heaters, cleanouts and devices
- Confirm with the landlord who approves the work
