Septic service in Ottawa
A grease trap behaves like a deadline. Fats cool, separate, and build a layer that keeps thickening until the trap stops separating anything and grease moves into the line beyond it — and at that point the problem is a plugged lateral or a backed-up floor sink in the middle of service, not a scheduled pump. Ottawa's restaurants, taverns, school kitchens, and church halls are mostly running interceptors sized for whatever volume they had when they were installed, which is why a menu that changed years ago often explains a trap that suddenly needs attention monthly instead of quarterly. Kitchens here have a practical advantage that operations farther out don't: the Ottawa WWTP is in town, so a hauler's round trip on a grease job is short. That shows up as easier scheduling and less pressure to be batched into a route that only comes through once a month. Pumping typically costs $200 to $450 depending on trap capacity, how solid the contents have gone, and whether the unit sits inside under a floor hatch or outside in a vault. Keep the service records. Whether a kitchen is on city sewer or a private system, whoever asks about grease handling — the sewer authority, a health inspector, an insurer after a backup — asks for dates and volumes, and a hauler's manifests are the cleanest form of that answer.
Seasonal Tip
Holiday and banquet season pushes volume through a kitchen well past its normal rate. Move an Ottawa trap's service up ahead of November rather than discovering mid-December that a quarterly schedule was fine in August and isn't anymore.
Frequently Asked Questions — Grease Trap Pumping in Ottawa
How often does my grease trap need pumping?
It depends on trap capacity and how much grease the kitchen actually produces, not on a universal rule. Fryer-heavy operations and high-cover restaurants often need monthly service, while a low-volume kitchen with a large outdoor interceptor may go quarterly. The practical test is the depth of the grease and solids layer at service: if it's roughly a quarter of the trap's depth, you're waiting too long.
What happens if I skip a service?
Grease carries past the trap and cools in the lateral, where it hardens and narrows the pipe. The first sign is usually a slow floor sink or a three-compartment sink that won't drain during the dinner rush, and the fix at that stage is jetting the line on an emergency call rather than a routine pump. It costs more, and it happens at the worst possible hour.
Can my dish crew just skim the trap instead?
Skimming the top layer doesn't remove settled solids, and it creates a disposal problem you don't want, since grease can't go in a dumpster or down any drain. Licensed haulers pump the full contents, clean the baffles, and leave a manifest showing where the waste went. That documentation is what protects the business if anyone ever asks how grease is being handled.
Does trap size change what I pay?
Yes. The $200 to $450 range mostly reflects capacity and access. A small under-sink unit is quick. A large outdoor interceptor takes more time and puts more volume on the truck. Contents that have gone hard, or a lid that has to be dug out, add labor. If you're scheduling regularly rather than in a crisis, ask what pricing looks like on a standing route.
