Grease trap cleaning in Belgium

In a restaurant, canteen or any professional kitchen, the grease separator works at every service. Kept maintained, it holds fats back before the sewer. Neglected, it saturates, overflows and lets grease into your pipes.

Our visit

Emptying, cleaning and checks, done properly

Grease-trap maintenance goes further than pumping out the contents. We follow a full method so the separator regains capacity and stays documented.

  1. 01

    Full emptying

    We draw off the entire contents of the trap: solidified surface grease, water and sludge settled at the bottom. The separator regains its full useful capacity, not just a clean-looking surface.

  2. 02

    Wall and baffle cleaning

    We clean walls, baffles and fittings to lift the deposits that cling on, where a simple pump would leave grease stuck and speed up the next saturation.

  3. 03

    Check and compliance

    We inspect the tank condition plus the inlets and outlets, and flag any wear that could hinder separation before it blocks service.

  4. 04

    Traceable disposal

    Removed grease and sludge go to an authorised treatment route, with documentation that covers you in an inspection and proves the maintenance really took place.

Frequency and compliance

A maintenance rhythm built for your kitchen

There is no single frequency that fits every site. A restaurant serving dozens of greasy covers at lunch does not need the same cadence as a small staff canteen. A reliable gauge remains the grease layer: empty before it takes too much of the tank. In practice that often means monthly through to every few months. We assess your real situation and agree a realistic calendar with you.

Beyond smooth running, this upkeep has a compliance angle. Sites that handle food fats are expected to keep a separator in working order and to show that it is maintained. By documenting each empty and each check, we build a clear history you can show an inspector or network manager.

That preventive approach changes everything next to emergency call-outs. Instead of waiting for the blockage that stops service on a busy night, you schedule maintenance outside peak hours. More predictable, less stressful, and it protects your pipes as much as your trade.

What a grease trap does

The quiet link that protects your pipes

A grease trap, or grease separator, is a tank between your kitchen sinks and the sewer network. Waste water slows inside it: fats and oils, lighter than water, rise and stay trapped at the surface, while cleaner water continues to the drain. That ongoing split stops grease from setting in your pipes and blocking them over time.

The trap still fills. Day after day the grease layer thickens and deposits build at the bottom. Past a threshold the separator has no room left to work: fats spill downstream: exactly what it was meant to prevent. For a kitchen that produces large amounts of fat every day, that tipping point arrives sooner than people expect.

So a grease trap is not kit you fit and forget. It needs regular maintenance, planned around your activity volume. Kept on track, it spares you blockages, bad smells and compliance headaches. Left alone, it becomes the first cause of your drainage trouble.

Signals to watch

Signs that maintenance is due

If you recognise any of these in your kitchen, the separator is nearing saturation. Better to schedule an empty without delay.

  • Water drains more and more slowly from the kitchen sinks.
  • A greasy or sewer smell rises from the drains during service.
  • Solidified grease is visible in the trap or on the outlet pipes.
  • You keep calling for urgent help with ever more frequent blockages.
  • The separator overflows or backs up at peak times.
  • The last documented empty was months ago, with no follow-up.

Before we arrive

Good habits between visits

Between visits, a few simple kitchen habits slow how fast the separator fills and space out the empties.

  1. 01

    Scrape the plates

    Bin leftovers and sauces before washing up: less grease down the sink means a slower-filling trap.

  2. 02

    Do not pour oil down the sink

    Frying oils and cooking fats go in separate collection, never into the drain where they set and saturate the separator.

  3. 03

    Schedule the emptying

    Set a regular maintenance calendar rather than waiting for the blockage: a preventive rhythm avoids nasty surprises.

  4. 04

    Keep access clear

    Leave the separator cover reachable and free of storage so the visit can start without useless handling.

How much does this service cost?

Our call-outs start from €72.60 incl. 21% VAT (non-residential premises). The cost of grease-trap maintenance depends on separator size, how full it is and the agreed frequency.

How often should a grease trap be emptied?

Frequency depends on how much grease your kitchen produces and on separator size. A busy restaurant often needs service every one to three months. A small canteen can space visits further. As a rule of thumb, empty before the grease layer takes too much of the useful height. We assess your real situation and propose a rhythm that is neither too tight nor risky for drainage.

What happens if I neglect separator maintenance?

The trap saturates: fats spill downstream, sinks slow, smells rise and blockages multiply: often at the worst moment of service. You also lose proof of regular upkeep, useful in an inspection. Planned maintenance costs less money and less stress than repeated emergencies.

What exactly does your visit include?

Full emptying (surface, water and bottom sludge), scraping of walls and baffles, rinsing, inlet and outlet checks, then disposal of waste through a licensed route with a traceability document. We do not stop at sucking off the surface crust.

Is greasy waste disposed of properly?

Yes. Grease and sludge go to an authorised treatment route. You receive the paperwork that evidences disposal: useful for your maintenance file and if an inspector or network manager asks.

Should I keep proof of maintenance for regulations?

Yes, it is strongly recommended. Sites that handle food fats should be able to show a separator exists and that it is maintained. We leave a clear history at every visit.

Do you have to shut the kitchen during the job?

Not necessarily. We often schedule outside service hours to limit impact. Depending on access and volume, a short pause can help. We say so in advance so you can organise service.

When should you call a drain technician straight away?

Some signs mean the blockage is no longer local: waste water backing up into a shower, sink or toilet, several fixtures draining slowly at the same time, water rising from a yard gully, or a sewer smell that lingers despite ventilation. In those cases, avoid reaching for chemical drain cleaners again and again: they attack seals and pipework without reaching a blockage further down the run.
