There's a version of grease trap pumping that moves waste from point A to point B and calls it done. Then there's the Ferguson version — where pumping is the first step in a documented, inspection-ready service that tells you exactly what was inside your trap and what condition it's in now.
Commercial kitchens in Walla Walla run on predictability. Your grease trap pumping schedule should work the same way: consistent, documented, and never something you have to chase down.
Ferguson provides grease trap pumping for restaurants, institutional kitchens, food processing facilities, and multi-unit operators across Walla Walla, WA. We work around your schedule, not ours, and we leave you with paperwork that holds up under any inspection.
Where Pumping Fits in Your Grease Management Program
Routine Scheduled Pumping
The foundation of any compliant grease management program. Based on trap capacity and kitchen output, we establish a pumping interval — typically every 30 to 90 days — and hold to it.
Pre-Inspection Pumping
Health inspections, sewer authority audits, and environmental reviews all carry more weight when your grease trap records are clean and current.
Post-Event and High-Volume Pumping
Banquets, catering events, seasonal rushes — we provide on-call pumping for volume spikes that fall outside your routine cycle.
New Location Baseline Pumping
Acquired a new space? We perform a baseline pump-out and inspection so you know exactly what you're starting with.
Where Grease Trap Pumping Fits in Walla Walla's Regulatory Environment
Most jurisdictions in Walla Walla, WA require documented grease trap service as part of their fats, oils, and grease (FOG) compliance programs. Ferguson's pumping service includes full waste documentation as a standard deliverable — not an upgrade.
Common Situations We Handle
"We Don't Know When It Was Last Done" Call
We handle baseline pump-outs without judgment and build your records from here forward.
The Odor Complaint That Won't Go Away
Pumping addresses the capacity issue immediately. Our inspection identifies whether something structural is contributing.
The Slow-Drain Investigation
We pump the trap first and re-assess. In most cases, the source is a grease trap at or near capacity.
The Multi-Unit Coordination Headache
Ferguson provides coordinated scheduling, consolidated reporting, and a single point of contact across all your Walla Walla, WA locations.
💡 Why Pumping Frequency Is Not One-Size-Fits-All
The "pump it every 90 days" standard is a reasonable starting point, but it's not a rule. Here's what actually drives your pumping interval:
- 📦 Trap capacity — A 500-gallon interceptor can absorb more output than a 50-pound under-sink unit.
- 📦 Kitchen type — High-volume fried food operations produce significantly more FOG.
- 📦 Seasonal variation — Summer catering and holiday rushes require schedule adjustments.
- 📦 Baffle condition — Damaged baffles change how urgently pumping is needed.
Ferguson establishes your pumping frequency based on a first-service assessment, not a generic default.
