Interceptors, gullies and pump stations for business sites along the Great West Road, and drains and grease traps for Hounslow’s homes and high streets.
Hounslow sits under the Heathrow flight path, with offices and business parks along the Great West Road, industrial estates around Feltham and Brentford, and a busy town centre full of restaurants and takeaways. It’s all on mains drainage, so our work here is commercial drainage, drains and grease traps.
Business sites need interceptors and gullies cleaned and pump stations serviced. The streets of inter-war semis and terraces have drains that crack in the London Clay and block with fat and wipes. The River Crane runs through the borough, and low ground near it can flood.
We’re SafeContractor, Achilles UVDB and RISQS approved, our crews work in London most days, and we answer the phone 24 hours a day.
Offices, depots and industrial units need interceptors emptied and gullies cleaned to keep oil and silt out of the drains. Our jet/vac tankers handle both, with waste transfer notes for every load.

We clear blocked drains in houses, flats and shops with high-pressure jetting and survey them with CCTV when they keep coming back.

Hounslow’s high streets have a lot of restaurants and takeaways, and every one needs its grease trap emptied before fat reaches the drains. We set up a schedule and leave a waste transfer note every time.

Business sites and some newer developments rely on pump stations. We service them, test the pumps and alarms, and respond 24/7 when one fails.

Business parks, busy high streets and the River Crane.
Sites with car parks and yards should have interceptors inspected and emptied regularly, with records kept.
With so many food outlets and homes, fat and wipes are the most common causes of blockages.
Low ground near the Crane can flood after heavy rain. Clear gullies help water get away.
