Longmont utility backflow testing requirements
Longmont is a very strong Colorado utility because it combines annual testing, enforcement timing, irrigation-specific upgrade rules, and a real portal transition.
Fast answer
Who, when, and what device?
Longmont requires annual testing by certified testers, says new and replacement assemblies must be tested after installation, and publishes a notice-and-enforcement sequence that starts 45 days before the due date and can escalate to civil penalties and water suspension.
- Who is affected
- Longmont customers with backflow assemblies, especially non-single-family properties, irrigation services, and homes with higher-hazard conditions like fire suppression or boilers.
- Covered devices
- Reduced pressure zone assemblies · Irrigation backflow assemblies · Protected cross-connection assemblies · Assemblies reported through SwiftComply
- Risk if missed
- Longmont adds a fee 31 days past due, warns of escalated civil enforcement at 61 days, and can assess civil penalties up to $500 per assembly with service interruption scheduled at 91 days past due.

Local detail
Property, device, and enforcement notes
Open the parts that match the property and system. These details stay subordinate to the fast workflow above.
Program and failure notes
- Longmont publishes one of the clearest due-date escalation ladders in the set.
- Irrigation upgrade rules are operational and monetizable.
- SwiftComply adoption is already part of the public workflow.
- 45-day reminders go out before the due date.
- 31 days past due triggers a fee and city-contracted outreach.
- 91 days past due can trigger up to $500 per assembly and service interruption.
Residential notes
- Longmont is unusually useful for residential pages because the city explicitly mentions irrigation, fire suppression, and boiler scenarios.
- Single-family homes are not automatically in the program, but the city gives concrete examples of when they are.
Commercial notes
- Commercial and multifamily intent is extremely strong because Longmont publishes a real notice, fee, and penalty ladder.
- This is one of the best non-Texas utility pages for recurring commercial lead intent.
Irrigation
Longmont has especially strong irrigation content because DCVAs are no longer approved long term on irrigation lines and failed units must move toward RP protection.
- Irrigation systems are treated as high-hazard cross-connections.
- A failed irrigation DCVA must be replaced with an RP within 60 days or repaired on a two-year replacement timeline.
- The city now routes submission through SwiftComply.
Fire line
Longmont is less public about fire-line staffing than Tallahassee or West Palm, but it still names fire suppression as a trigger for protected residential and commercial services.
- Homes with fire suppression can be pulled into the program.
- Commercial fire-protected buildings stay inside the same testing and enforcement ladder.
- RP assemblies are the default new or replacement expectation.
Cost and fee context
Testing is market-priced, but Longmont adds a $10 passing-test portal charge and escalating late-compliance costs.
Repair and retest costs rise quickly on irrigation upgrades and failed assemblies.
The main cost pressure is avoiding late fees, civil penalties, and shutoff scheduling.
Evidence ledger
Official sources
Longmont is one of the strongest Colorado pages because it publishes annual due-date ranges, a 45-day reminder, fee and penalty escalation, and a hard shift to SwiftComply for test submissions.
BackflowVerdict summarizes these records; the governing entity remains the authority.
