Restaurant Plumbing & City of Portland FOG Compliance
Portland's Bureau of Environmental Services strictly regulates fats, oils, and grease (FOG) entering the municipal sewer system. Restaurants must maintain code-approved grease interceptors and schedule regular hydro-jetting to prevent catastrophic kitchen line backups and municipal fines.
Certified Backflow Prevention Assembly Testing & Certification
The State of Oregon and the Portland Water Bureau mandate that commercial properties test all backflow prevention assemblies annually to prevent contaminants from siphoning into the public potable water system. Our certified testers handle inspection, repair, and state reporting seamlessly.
Transparent Pricing & Cost Factors
Commercial pricing accounts for specialized commercial tooling, after-hours facility access, backflow testing certifications, and city commercial permit guidelines.
- Building type (downtown commercial tower vs. ground-floor restaurant or retail strip)
- Service timing (daytime service vs. after-hours/night shift to avoid business disruptions)
- Equipment scale (commercial grease traps, hydro-jetters, backflow assemblies)
- Compliance documentation (City of Portland BES FOG requirements and BDS filings)

The City of Portland Bureau of Environmental Services issues notices of violation and escalating fines for unmaintained grease interceptors or clogged sewer discharges.
