Grease trap service, managed across every location

From under-sink traps to in-ground interceptors, Waste Harmonics Keter manages your grease trap pumping as a single managed partner, not a broker. One point of contact, one invoice, manifests you can defend at inspection.

Why it matters

A neglected trap can close a kitchen

Grease trap waste is regulated at the local level, with a different FOG rule in nearly every jurisdiction. Multi-site operators typically manage it site by site, with a different pumper in every market, missed service dates, and no manifests when the health inspector or municipality asks. The result is backups, odors, fines, and closed kitchens.

We make grease trap service scheduled, documented, and consistent everywhere you operate.

What We Manage

What counts as grease trap service we manage

Grease trap waste is the fats, oils, grease, and solids captured by traps and interceptors before they reach the sewer. We manage the pumping, cleaning, and documentation through one consistent program across every location.

Our Process

How WHK manages your grease trap program

We start by mapping what you generate across every location, then standardize your program with one cadence and vetted recyclers everywhere. Scheduled pickups come with chain-of-custody records, and your materials are processed responsibly with diversion and activity rolled into one report.

Assess

We map your trap and interceptor inventory, local FOG requirements, current pumpers, and where documentation is missing.

Standardize

One program: pumping schedules matched to trap size, kitchen volume, and local rules, with vetted providers in every market.

Collect & document

Scheduled pump-outs with manifests and chain-of-custody records you can defend at inspection.

Recycle & report

Trap waste routed to permitted processing facilities; service and compliance rolled into one report.

Why multi-site food generators trust WHK

Get Started
One partner, full accountability

We don't broker your program. We own the relationship at every location you operate, which means we're answerable for what happens from pickup to final processing.

Recyclers you can audit

Every facility in our network is vetted and documented. Chain of custody records follow your materials through every step, giving you the evidence you need for compliance and ESG reporting.

Reporting built for review

Consolidated data across all locations rolls into one report. No piecing together invoices from five different vendors or explaining gaps in your diversion numbers to auditors.

Real accountability

We own your program end to end, not as a broker passing you between vendors.

FAQ

Common questions about our program and services.

How often do grease traps need to be pumped?

It depends on trap size, kitchen volume, and local requirements. Many jurisdictions enforce the 25% rule, pumping once grease and solids reach a quarter of the trap's capacity. We build each site's schedule around its volume and local rules.

What's the difference between a grease trap and a grease interceptor?

Both capture fats, oils, and grease before they reach the sewer. Traps are smaller units installed under or near sinks; interceptors are larger in-ground tanks serving the whole facility. Both require scheduled pumping and documentation under local FOG rules.

Can you provide documentation for health inspections?

Yes. Every pump-out generates manifests and chain-of-custody records, kept current and accessible across your sites.

Do you also collect used cooking oil?

Yes, used cooking oil collection is a separate recyclable stream with its own service and value. See our Used Cooking Oil page or ask us about combining both in one program.

Can you manage grease trap service across all our locations?

Yes, one managed program, consistent schedules, and one invoice across every site nationwide.
