Interceptors and gullies, grease traps, blocked drains, pump stations and tank emptying for businesses and homes in Shoreham-by-Sea and the Adur valley.
Shoreham-by-Sea is a working town. Between the port, the industrial estates and the business units around the airport, a lot of the work we do here is commercial: emptying oil interceptors and silt traps, cleaning gullies on yards and car parks, and clearing drains before a blockage shuts a site down.
In the town centre and along the seafront, cafés, pubs and restaurants need their grease traps emptied, and older properties need their drains cleared and surveyed. Newer developments often depend on pump stations, which need regular servicing to keep working.
Up the Adur valley, around Coombes, Botolphs, Bramber and Upper Beeding, and on the farms of the downs, there are still homes on septic tanks, cesspits and treatment plants. We empty and service those too. Everything is covered from our yard in Copthorne, 24 hours a day, 365 days a year.
Yards, car parks, workshops and wash bays often drain through an oil interceptor or silt trap, which needs emptying before it fills and lets pollution through. Our jet/vac tankers jet and vacuum in one visit, and we’re SafeContractor, Achilles UVDB and RISQS approved, so we can meet your contractor checks and get onto managed sites.

Restaurants, cafés, pubs and staff canteens need their grease traps emptied to stop fat getting into the drains. We work to a schedule that suits how busy you are, and leave a waste transfer note every time so your duty of care records are complete.

We clear blocked drains with high-pressure jetting, and if a drain keeps blocking we’ll put a camera down it to find out why. You get a written report showing any cracks, displaced joints or root ingress, ready for landlords, facilities managers, insurers and buyers.

We service and repair pump stations on estates and commercial sites, and empty septic tanks and cesspits and service treatment plants for homes and farms up the Adur valley and on the downs. Our tankers hold 2,000 to 4,000 gallons.

A port, an airport, a river and the downs all within a few miles.
Keep a record of every interceptor empty. The Environment Agency, your insurer or your landlord may ask for it.
Parts of the town sit low beside the Adur and the sea. Drains there have little fall and can be affected by high tides and groundwater.
The downs above the town are chalk, which holds groundwater used for drinking. Close to the most sensitive sources, discharging to the ground can need a permit.

★★★★★So glad we found them. The team was professional, courteous and helpful. They came the next day and pricing is way more competitive than a national chain. Will be using them again in a year's time to service the pump. Thanks again!
