Denver Metro, CO Backflow & Grease Trap FAQs

Direct answers sourced from Denver Water — Cross-Connection Control & Backflow Prevention Program and City and County of Denver DOTI Wastewater Management Division (WMD) & Metro Water Recovery regulations.

How do I submit my annual backflow test report to Denver Water, and is there a portal fee?

Denver Water does not charge a portal fee ($0). Your certified tester submits the completed Denver Water Backflow Assembly Test & Maintenance Report directly by email to CrossConnectionControl@denverwater.org (with 'Backflow Test Reports' in the subject line) or by fax to (303) 794-8325. Failed assemblies must be reported to Denver Water within 24 hours at (303) 628-5969.

Why did Denver Water add a $250 backflow penalty in 2025–2026, and what did HB25-1077 change?

Effective May 1, 2025, Denver Water assesses a non-refundable $250 penalty and places water service into suspension status if an annual backflow test or required assembly installation is not completed within 60 days after three mailed notices. On the positive side, Colorado passed HB25-1077 in 2025, allowing ABPA- and ASSE-certified backflow testers to inspect, test, and repair domestic and irrigation assemblies without requiring a master plumbing license—saving homeowners and businesses hundreds of dollars on routine tests and minor repairs. (Fire line backflow assemblies still require a State of Colorado Fire Suppression System Contractor–Backflow credential.)

What are the commercial grease interceptor (FOG) rules in the City and County of Denver?

Under the City and County of Denver Department of Transportation and Infrastructure (DOTI) Wastewater Management Division (WMD) policy (updated August 17, 2026), outdoor gravity grease interceptors must be pumped and cleaned before combined FOG and solids reach 25% of liquid capacity, while indoor hydromechanical traps must be cleaned before reaching 80% of rated grease or solids capacity. Signed maintenance manifests must be retained on-site for DOTI inspectors, and haulers disposing at Metro Water Recovery's Robert W. Hite Treatment Facility (6450 York St) must hold a Non-Hazardous Routine Hauled Waste Discharge Permit.
