Interceptors, gullies, pump stations, grease traps and drains looked after for business parks, managed estates and homes across Farnborough.
Farnborough is known for aviation, from its airport to the international airshow, and the town is ringed with business parks, warehouses and offices. Those sites have car parks, service yards and plant that need their drainage looked after: oil interceptors, gullies, pump stations and the drains that connect them. That’s a big part of what we do here.
Alongside the business parks, Farnborough has large residential estates, old and new. Older homes have clay drains that block and crack; newer developments often rely on private pump stations run by management companies. We clear, survey and service both.
We’re SafeContractor, Achilles UVDB and RISQS approved, so we can meet the contractor checks that managed sites ask for. Our tankers and engineers work in Hampshire most days, and we’re on call 24 hours a day, 365 days a year.
Oil interceptors and gullies stop fuel, oil and silt getting into the drains from car parks, loading bays and yards. They only work if they’re emptied and cleaned. Our jet/vac tankers empty interceptors, clean gullies and leave you the waste transfer notes you need for your environmental records.

Business parks and newer housing often depend on a pump station. We service them on a planned schedule, testing pumps, floats, alarms and control panels and cleaning the wet well, and our confined space teams can work safely inside when needed. If one fails, we come out day or night.

From office blocks to family homes, we clear blocked drains with high-pressure jetting and survey them with CCTV so you can see what’s causing the problem. You get a written report you can share with your facilities team, landlord or insurer.

Staff canteens, restaurants and takeaways all need their grease traps emptied regularly. We set up a schedule to suit how busy your kitchen is and leave a waste transfer note every visit.

Business parks, big estates and the paperwork that goes with them.
If your site has an oil interceptor, keep records of when it was emptied and inspected. Waste transfer notes from each visit are part of that.
Many estates and business parks have pump stations that the water company doesn’t look after. A planned service is cheaper than an emergency call-out.
Much of the area is on sandy ground with mature trees, and roots can find their way into older drains. A CCTV survey shows whether that’s your problem.
