Large-capacity grease interceptors — the 500 to 1,500-gallon systems serving high-volume restaurants, institutional kitchens, food processing operations, and multi-tenant commercial buildings — operate under tighter regulatory oversight and carry heavier consequences for service gaps than standard kitchen grease traps. Bob's Septic & Grease Service has managed these systems across Lake Oswego, OR with the same relationship-first approach that defines everything Bob's does: measured intervals, complete interior cleaning at every service, and documentation that satisfies pretreatment program requirements from the first visit.
Built for Situations Like These
The restaurant that's grown past its original interceptor program.
When a kitchen's output increases — new equipment, extended hours, added service — the fill rate increases while the service schedule stays the same. Bob's measures current accumulation rates and recalibrates.
The institutional facility under active pretreatment oversight.
Healthcare, university, and large-scale contract food service operations face documentation requirements that exceed standard health department formats.
The multi-tenant commercial kitchen building with one shared interceptor.
Fill rate is the sum of all tenants' output. Bob's coordinates service timing and produces documentation that satisfies both building-level and individual tenant needs.
The property with both a grease interceptor and a septic system.
Bob's manages both. For facilities in Lake Oswego, OR where the grease system and the septic system interact, having one provider who understands both is a material advantage.

What Working With Bob's in Lake Oswego, OR Feels Like
It feels like having a provider who knows your system. Service confirmations before each visit. Condition reports with specific observations after each visit. Proactive communication when fill rate data or component condition suggests a change is needed.
For multi-site and multi-tenant operators in Lake Oswego, Bob's handles the coordination entirely — one documentation standard, one consolidated report, one service contact for every question about every interceptor in the portfolio. The administrative complexity disappears because Bob's absorbs it.
Delays, Risks, and Hidden Issues
The baffle that looks functional from the access lid and isn't.
Internal baffle degradation in large interceptors is invisible from outside. Bob's inspects internal baffle condition at every service visit.
Sludge consolidation that makes the next job more expensive than the last.
Organic sludge past its service window compresses and hardens. Bob's measured intervals keep the system ahead of the consolidation threshold.
Documentation that satisfies a receipt requirement but not a pretreatment reviewer.
Bob's produces complete pretreatment-grade records at every interceptor service visit — as a standard deliverable.
Why Your Grease Interceptor May Be Out of Compliance Between Service Visits — Without Anyone Knowing
Here's a situation Bob's encounters regularly with new interceptor accounts in Lake Oswego, OR: the facility has been receiving service on a regular schedule, the records look reasonable, and the system hasn't overflowed. By any surface measure, everything appears to be under control.
Then Bob's measures the actual fill rate at the first visit — tracks the combined FOG and sludge depth on arrival, calculates the accumulation since the prior service — and finds that the system has been hitting the 25% regulatory threshold somewhere around day 18 to 20 of a 30-day service cycle. For ten to twelve days every month, the interceptor has been over-threshold, and FOG has been passing untreated into the municipal sewer.
The fix is straightforward: measure the actual fill rate, recalibrate the interval to the measurement, and maintain that interval as the facility's output changes. Bob's does this for every new interceptor account in Lake Oswego.
What Clients Are Saying
"Bob's measured our interceptor's actual fill rate on the first visit and told us we'd been over-threshold for about ten days every month for who knows how long. We hadn't overflowed, so nobody had flagged it. They adjusted our interval, and our pretreatment record has been clean since. That measurement changed everything."
Owner — Large-Format Seafood Restaurant
"Our facility has both a grease interceptor and a septic system, and the coordination between the two has always been a concern. Bob's manages both, understands how they interact, and coordinates service so the two systems stay balanced."
Director of Facilities — Assisted Living Community
"Nine tenant kitchens on one interceptor — the documentation challenge alone seemed unmanageable. Bob's built a tracking approach and gives me one clear compliance package quarterly."
