Grease traps, drain clearance and CCTV surveys, pump stations, interceptors and tank emptying for homes and businesses across Worthing and the villages nearby.
Worthing is a large town, and most of it is on mains drainage, so the bulk of our work here is commercial and drain-related. Restaurants, takeaways, pubs and care home kitchens need their grease traps emptied; industrial estates and car parks need their interceptors and gullies cleaned; and blocked drains at shops, offices and blocks of flats need clearing fast.
Across the residential areas, from Goring and Durrington to Broadwater and East Worthing, we clear blocked drains, survey problem ones with a camera and service the pump stations that newer developments depend on.
Head north onto the downs, around Findon, Patching and Clapham, and some homes and farms are off the mains, on septic tanks, cesspits or treatment plants. We empty and service those too. Everything is covered from our yard in Copthorne, 24 hours a day, 365 days a year.
Fat, oil and grease from commercial kitchens sets hard in drains and is one of the most common causes of blockages. We empty grease traps on a schedule that fits how busy your kitchen is, early or late if you’d rather we weren’t there during service, and leave a waste transfer note every time.

We clear blocked drains with high-pressure jetting, and if a blockage keeps coming back we’ll survey the drain with a camera to find out why. Written CCTV reports are useful for landlords, managing agents, insurers and anyone buying a property.

Many newer developments and commercial units rely on a pump station. When a pump wears out, a float sticks or the chamber fills with rags and fat, the alarm goes off. We service pump stations, test the pumps, floats and alarms, clean out the wet well, and come out 24/7 when one fails.

Industrial estates, car parks and trade premises often drain through oil interceptors and gullies that need regular emptying. Our jet/vac tankers jet and vacuum in one visit, and we’re SafeContractor, Achilles UVDB and RISQS approved for managed sites.

A few things we see a lot in and around the town.
Most blockages in commercial drains are caused by fat, oil and grease. A properly sized, regularly emptied grease trap stops it reaching the drains.
Drains that only serve your property are usually yours. Since 2011, shared drains and the section outside your boundary are usually the water company’s.
North of the town, the downs are chalk that holds drinking water. Close to the most sensitive sources, off-mains systems discharging to the ground can need a permit.

Questions answered
