Degreasing and interceptor cleaning removes built-up oil, grease and silt from plant, floors, gullies and oil-water separators before it becomes a blockage, a slip hazard or a pollution incident — interceptors and separators are commonly recommended to be emptied annually as a minimum, and sooner once a significant build-up of oil or silt is present. Optus Glean UK carries this out UK-wide, with waste handled to environmental duty-of-care requirements.
What we clean
Grease and oil build-up on plant, floors, extraction and kitchen or process equipment; gullies and drainage channels; and oil-water separators and interceptors serving vehicle washes, workshops, loading bays and yards.
Why interceptor cleaning is a compliance issue, not just housekeeping
Discharging oily water to a sewer or watercourse without the right consent can be an offence under the Water Resources Act 1991 and the Environmental Permitting Regulations 2016. Recommended good practice is to empty a separator as soon as a significant quantity of oil or silt has built up, and to refill it with clean water before putting it back into service — with events such as cleaning, repairs and incidents recorded.
Waste oil and separator waste is treated as hazardous waste, and as the waste producer you are responsible for it under the Duty of Care Code of Practice — meaning it can only be transferred to a registered waste carrier and a suitably licensed facility, with the paperwork to prove it.
What the visit covers
We remove and dispose of accumulated oil, grease and silt, jet and clear connected gullies and drainage runs where needed, and provide waste-transfer documentation for your environmental records. Frequency is set to the site's actual build-up rate rather than a single fixed interval — a busy vehicle wash or commercial kitchen needs this far more often than a lightly-used yard gully.
Who this is for
Vehicle workshops and washes, distribution and logistics yards, commercial kitchens and food manufacturing sites, and any industrial site with a grease trap, gully or interceptor as part of its drainage.
