Grease Trap & Sewage Treatment Services in South West London – Expert Wastewater Specialists

A grease trap (grease interceptor) captures fats, oils and grease (FOG) before they enter your drainage system. UK food businesses must manage FOG to prevent blockages and pollution, and your local water company or authority may require an approved grease management system (often a grease trap) to remain compliant.

Sizing depends on kitchen throughput, sink/combination oven discharge, and peak flow rates. We carry out a site survey and specify a correctly sized unit to meet water company guidance. Most under-sink units install within a day; larger in-ground interceptors may take longer depending on access and groundworks.

Most commercial grease traps need professional cleaning every 1–3 months depending on kitchen size and food volume. Regular servicing prevents odours, blockages and environmental fines. We can set up a tailored maintenance schedule for your site in South West London.

Common signs include foul odours, slow-draining sinks, gurgling, visible grease build-up in the trap, and recurring downstream blockages. These indicate the trap needs cleaning, seals may be worn, or flow rates are exceeding capacity. We can inspect, clean and reset service intervals.

As a rule of thumb, septic tanks should be emptied yearly. Busier households or commercial sites may need more frequent desludging. Routine maintenance keeps the system efficient, prevents overflows and supports compliance with Environment Agency guidelines.

A septic tank stores and partially breaks down wastewater before discharging to a soakaway or drainage field. A sewage treatment plant actively treats wastewater, producing cleaner effluent for safer environmental discharge. We can advise on the most suitable option for your property and install/maintain both systems.

If you produce hot food (restaurants, takeaways, pubs, hotels, schools, care homes), you must prevent FOG from entering the sewer. Your water company may stipulate a grease trap or equivalent FOG management solution.
