Grease Interceptor Cleaning in Vancouver, WA
A high-volume kitchen runs on a different scale of grease infrastructure than a small cafe, and it needs a pump truck, not a hand scoop. We pump the unit, inspect it while it's empty, and hand you signed waste-hauling manifest documentation the same visit.
Built for Volume a Grease Trap Can't Handle
A grease interceptor is not a bigger version of a grease trap, it's a different piece of infrastructure entirely, built for a different scale of kitchen. Where a grease trap is a 20 to 50 gallon steel or plastic box installed under a single sink, an interceptor is a precast concrete or fiberglass tank, typically 500 to several thousand gallons, installed underground or in an outdoor enclosure and plumbed to handle an entire high-volume kitchen's wastewater line. Large restaurants, food halls, and institutional kitchens are required by code to run an interceptor at that scale rather than a point-of-use trap, since a trap's capacity simply can't keep pace with that volume of grease-laden water.
Servicing that scale of unit requires a vacuum pump truck, not a hand scoop, and our commercial kitchen specialists run scheduled pump-outs based on your kitchen's actual accumulation rate rather than a generic calendar interval. Local sanitation district rules require pumping once accumulated grease and solids reach 25% of the unit's liquid depth, the same threshold used for smaller traps, but interceptors reach that mark on their own timeline, driven by your kitchen's real volume.
Documentation is where interceptor service differs most from a smaller grease trap. Every pump-out includes signed, licensed waste-hauling manifest paperwork showing volume removed, disposal location, and service date, exactly what a health department or sanitation district audit asks to see. We keep a copy on file so your compliance record is never dependent on someone finding a slip of paper from six months ago.
Signs Your Grease Interceptor Needs Service
Slow-draining fixtures across multiple stations, not just one sink, is the clearest sign an interceptor rather than a smaller trap is behind the problem, since an interceptor serves the whole kitchen's line. A sewage or rancid odor near the outdoor enclosure or access lid, grease visibly surfacing at the unit's inspection port, or a sanitation district notice referencing your discharge levels each warrant a pump-out sooner than your current schedule allows.
If your pumping frequency has been creeping up even though kitchen volume has stayed steady, that's worth investigating on its own. It can mean the unit is undersized for how the kitchen has grown since installation, not just that it's due for service.
High-Volume Kitchens Across Vancouver
Vancouver's restaurant and food-service sector has grown well beyond what many buildings' original grease infrastructure was sized for, particularly in shopping centers and mixed-use developments along the Mill Plain and Fourth Plain corridors where a single interceptor sometimes serves multiple tenant kitchens sharing one wastewater line. Clark County's sanitation district treats interceptor compliance as seriously as it does grease trap compliance, and a facility serving several restaurants or a food hall draws closer scrutiny simply because a failure there affects more of the shared sewer system downstream than a single small kitchen would.
Properties that have added tenants or expanded kitchen operations since their interceptor was originally sized are exactly the kind of facility worth reassessing, since Uniform Plumbing Code sizing tables that fit the original build may no longer match current volume.
Our Process for Grease Interceptor Cleaning
Assess Accumulation
We measure grease and solids depth against the unit's total capacity to confirm service timing.
Vacuum Pump-Out
A pump truck fully extracts grease, solids, and wastewater from the interceptor.
Inspect the Unit
We check baffle chambers and the outlet for wear or damage while the tank is empty.
File the Manifest
You receive signed waste-hauling manifest documentation the same day, ready for an audit.
Cost Of Grease Interceptor Cleaning In Vancouver
Cost depends on tank size, accessibility, and how much has accumulated since the last pump-out.
| Service | Typical Price Range |
|---|---|
| Standard pump-out (mid-size unit) | $395 to $875 |

Grease Interceptor Cleaning FAQs
What's the difference between an interceptor and a grease trap?
A grease trap is a small point-of-use unit, often 20 to 50 gallons, installed under or near a single sink to serve a small kitchen. A grease interceptor is a much larger unit, typically 500 to several thousand gallons, installed underground or outdoors and plumbed to serve an entire high-volume kitchen's wastewater line. Interceptors require pump-truck service, not a hand-scoop, and are the code-required unit for larger operations.
How often does a grease interceptor need pumping?
Most Vancouver interceptors need pumping every 60 to 90 days, though high-volume operations like large restaurants and food halls often need monthly service. Local sanitation district rules require pumping once accumulated grease and solids reach 25% of the unit's liquid depth. We track your facility's accumulation rate over a few cycles and set a fixed schedule so you're never guessing.
How much does grease interceptor cleaning cost?
Standard pumping on a mid-size underground interceptor typically runs $395 to $875 per visit, with recurring scheduled service priced lower per visit than one-off calls. Large-capacity units and emergency same-day service run higher. Final pricing depends on tank size, accessibility, and how much grease and solids have accumulated since the last pump-out.
Do you provide waste manifests?
Yes. Every pump-out includes signed, licensed waste-hauling manifest documentation showing volume removed, disposal location, and service date, ready to hand over for a health department or sanitation district audit. We keep a copy on file so you can pull your service history at any time.
How is an interceptor different from a grease trap physically?
Physically, interceptors are large precast concrete or fiberglass tanks installed underground or in an outdoor enclosure, with multiple baffle chambers that give grease and solids a longer retention time to separate from the water. Grease traps are small steel or plastic boxes that sit indoors under or near a sink. Servicing an interceptor requires a vacuum pump truck; a trap can be serviced by hand in minutes.
What size interceptor does our facility need?
Sizing follows Uniform Plumbing Code tables based on your kitchen's flow rate, meal counts, and number of connected fixtures such as prep sinks, dishwashers, and floor drains. Higher meal volumes and more fixtures require a larger unit. We assess your kitchen's actual service volume and cross-check it against your current unit's rated capacity to confirm it's still sized correctly as your business has grown.
Can an undersized interceptor cause ongoing problems?
Yes. An undersized unit reaches the 25% accumulation threshold quickly, forcing more frequent pump-outs than your budget accounts for, and it's more prone to grease carryover into the sewer lateral, which can trigger sanitation district violations and backups. If your pumping frequency keeps climbing even with steady kitchen volume, we check whether the unit itself is undersized for your operation.
How long does pumping take?
Most standard underground interceptor pump-outs take 45 to 90 minutes depending on tank size and truck access. We schedule around your slower operating hours or early morning windows so the crew is off site before service ramps up, and larger or harder-to-access units are quoted with a realistic time estimate up front.
Is this covered by a guarantee?
Yes. Every interceptor pump-out and cleaning is backed by our workmanship guarantee. If an issue traces back to how the service was performed, we return and correct it at no charge. We also stand behind the accuracy of our manifest documentation for your compliance records.
