Interceptors, gullies, grease traps and pump stations for the hotels, car parks, logistics and cargo sites around Heathrow.
The area around Heathrow is one of the busiest commercial districts we work in. Airport hotels, long-stay car parks, cargo and logistics sheds, vehicle depots and offices line the roads around the airport, and every one of them has drainage that needs looking after.
Car parks and yards need interceptors and gullies cleaned to keep fuel and oil out of the drains. Hotel kitchens need grease traps emptied, often round the clock. Large sites rely on pump stations. Off-airport, the villages of Harmondsworth, Sipson, Harlington and Longford have homes with drains that need clearing too.
We’re SafeContractor, Achilles UVDB and RISQS approved, used to site inductions and security, and we answer the phone 24 hours a day, 365 days a year.
Long-stay car parks, vehicle depots and cargo sheds need oil interceptors and gullies emptied and cleaned to protect the drains and local rivers. We provide waste transfer notes for every load and can set up a planned schedule.

Hotel kitchens serving breakfasts, banquets and room service produce a lot of fat. We empty grease traps on a schedule that suits your operation, at night if needed, with paperwork every visit.

We clear blocked drains at hotels, offices and homes with high-pressure jetting and survey them with CCTV to find the cause.

Big sites, lots of vehicles and strict rules.
Car parks and depots must stop fuel and oil reaching the drains. Interceptors need regular inspection and emptying.
Many sites need inductions, passes or escorts. We arrange these in advance.
Hotel kitchens rarely stop. Grease traps may need emptying at night or more often than usual.
