Grease trap pumping clears fats, oils, grease and solids out of your interceptor before they choke your kitchen's drain line. Most restaurant traps need service every 4 to 8 weeks, but the real trigger is volume, not the calendar. Evanston Porta Pros services kitchens across the city and can set a schedule that matches how much you fry, and works alongside our septic tank pumping cost crews when a property runs both systems.
The rule that matters here isn't a date on a calendar. A grease interceptor gets pumped once fats, oils, grease and solids reach 25 percent of the liquid depth, and that number is what any competent tech is checking when they open your lid. Slow drains, a sour smell near the floor drain, or backup during a rush are the warning signs kitchen staff notice first. If your restaurant sits anywhere in Evanston and you're not sure where your interceptor stands, that's the question to ask on the phone before you book a truck. Commercial grease trap pumping isn't guesswork once someone measures the layer for you, and the same logic applies to a holding tank rental if your kitchen runs without sewer access. We also handle septic pumping service and general septic tank cleaning for properties that run both systems, and if you're comparing costs across services, our septic tank pumping cost page breaks that down separately from grease work.
Cost depends on trap size, how packed the interceptor is, and whether you need a same-day or emergency porta potty rental-style rush visit. Bundled with septic work, day rates run inside the bands below; a dedicated grease trap quote should always follow a look at your unit first.
| service | duration | low | typical | high |
|---|---|---|---|---|
| septic | day | 150 | 250 | 300 |
| septic | weekend | 50 | 100 | 150 |
| service_fee | day | 100 | 175 | 300 |
| service_fee | weekend | 400 | 700 | 1200 |
Weekend and after-hours work costs more because it pulls a crew off a normal route, the same way a rushed porta potty rental per day booking costs more than one planned in advance. If your kitchen only needs occasional handwashing support rather than trap service, look at handwashing station rental or a portable sink rental instead. For general questions about pricing structure across our services, the septic tank pumping cost guide is a useful companion read.
A trap that overflows sends grease straight into the sewer line, and that backs up faster than most owners expect, much like a dumpster weight limits violation catches a jobsite off guard. Health inspectors in food service also expect handwashing facilities to meet 29 CFR 1910.141(d)(2), which requires soap and a towel or hand-drying device at the sink, not sanitizer alone. That standard runs alongside your grease program, not instead of it: a clean kitchen needs both a working trap and compliant handwashing, whether that's a fixed sink or a hand sanitizer station rental supplement near the line. If you're building out a new kitchen or renovating one, our home renovation porta potty page covers short-term restroom needs during the buildout, and construction site services covers the rest of the jobsite. Restaurants near Wilmette, about 4.1 miles northwest of Evanston, and Niles, roughly 8.0 miles west, use the same pumping schedule logic: volume drives frequency, not the address.
Most commercial kitchens need pumping every 4 to 8 weeks, but the real marker is the 25 percent fats-oils-grease-and-solids depth threshold, similar in spirit to the interval guidance on our how often to pump a septic tank page. High-volume fryers hit that faster. A slow drain or backup during service means don't wait for the next scheduled date, call sooner, the same way you'd flag issues early using our septic tank warning signs checklist.
Yes. Emergency grease trap pumping runs on a faster response than routine scheduling, similar to emergency septic service calls. Expect a service-fee premium over a standard weekday visit, since it pulls a truck off its normal route on short notice.
Yes, if your property runs both systems. Bundling a grease trap visit with septic pumping service on the same trip often saves a second dispatch fee. Ask when you book so the crew brings the right equipment for both jobs in one stop, and mention it on our request a quote form so dispatch plans the route right.
Permit rules vary by property and use, so confirm placement and disposal requirements with the city before service. We don't guess at code numbers here; general permit questions for portable equipment are covered on our porta potty permit requirements page. Check our septic tank warning signs page for related signals your system needs attention.
Grease and solids get vacuumed out and hauled off for disposal by licensed handlers. It never gets dumped on-site or down a storm drain. If your event or jobsite also needs waste removal, see roll-off dumpster rental for solid waste separate from grease.
