Grease trap pumping in Ontario runs on a simple rule: pump before fats, oils and grease hit 25 percent of the liquid depth in the tank. Wait past that and grease starts moving downstream into the line. Ontario Porta Pros services restaurants, commercial kitchens and food trucks on a schedule built around that 25 percent mark, not a guess, alongside septic pumping service calls and porta potty rental drops for the same job sites.
There's no single answer, because a busy fryer line fills a trap faster than a coffee shop does. What matters is the 25 percent rule: once fats, oils, grease and solids reach a quarter of the liquid depth, the trap needs pumping. High-volume kitchens near downtown Ontario often land on a weekly or biweekly cycle. Lower-volume operations stretch longer, closer to the interval a portable restroom rental route might follow for a slower site. Ontario Porta Pros checks depth at every visit and sets the next date from what's actually in the tank, not a calendar guess. This is different math from a home septic system, which typically only needs pumping every 3 to 5 years depending on tank size and household size, covered in our septic tank cleaning page. If you're not sure which service applies to your property, our septic pumping service overview breaks down the difference, and the how often to pump a septic tank guide covers residential timing separately.
Grease trap pumping cost depends on tank size, grease volume and how far the crew has to travel. A standalone septic-style service call in Ontario runs in the range below; ask for a written quote before scheduling since grease volume changes the number.
| service | duration | low | typical | high |
|---|---|---|---|---|
| septic/grease call | day | 150 | 250 | 300 |
| septic/grease call | weekend | 50 | 100 | 150 |
| service fee | day | 100 | 175 | 300 |

A neglected trap backs up drains, triggers odor complaints and can shut a kitchen down mid-shift, the same way an overdue porta john rental service call causes complaints on a job site. Commercial grease trap pumping keeps that from happening, and it keeps grease out of the sewer line the whole building depends on. Ontario restaurants near Eastvale, 6.8 miles south, and Montclair, 7.4 miles northwest, use the same crews and the same pumping standard, since grease doesn't care about city limits, and the same trucks often stop by Upland, 8.3 miles northwest, and Jurupa Valley, 9.0 miles east. Employers running kitchen crews still need general sanitation covered under OSHA 1926.51(c), and any crew degreasing equipment with solvents or coatings falls under OSHA 1926.51(f)(1) washing rules for that specific task. If your kitchen also needs handwashing setups during a remodel or a temporary kitchen buildout, see handwashing station rental or portable sink rental, both of which meet the soap-and-towel standard in 29 CFR 1910.141(d)(2).
Emergency grease trap pumping is available when a trap backs up outside a normal cycle. Ontario Porta Pros treats these as same-priority calls, since a backed-up trap can stop food service. Combine that with our emergency septic service page if the issue involves the building's main line, not just the trap, and check emergency porta potty rental if a job site restroom needs a same-day swap too.
Slow drains, sewer smell near the kitchen floor drain, or grease visibly rising near the lid all signal an overdue trap. Call before it overflows, not after. Ontario Porta Pros runs emergency grease trap pumping service separate from routine scheduling, so a same-day call doesn't wait behind a route.
Yes. A grease trap catches fats and oils from kitchen wastewater before they reach the sewer; a septic tank handles a whole property's wastewater, and the septic tank warning signs page covers signs the tank side is overdue. Pumping intervals and equipment differ, and mixing the two schedules leads to overdue traps.
Yes, and most commercial kitchens do. Weekly, biweekly or monthly routes are common, set by grease volume rather than a fixed date. Ontario Porta Pros builds the route around your kitchen's actual output, similar to how a monthly porta potty rental route gets set around a job site's crew size.
It's hauled out and disposed of properly, keeping it out of the sewer system serving your building and the block around it, the same disposal standard covered on our what cannot go in a dumpster page for solid waste.
Yes, if the truck has a grease interceptor onboard or connects to one at a commissary, and food truck events often pair that with a festival restroom rental or county fair restrooms order for the crowd. Volume is usually lower, so intervals often run longer than a full-service kitchen.
Yes. Ontario Porta Pros delivers grease trap pumping across Ontario and the surrounding metro, with same-day and next-day drop-off available on most orders.
