Interceptors, gullies and drains for port and industrial sites, and drains, pumps and septic tanks for homes in Newhaven and the lower Ouse valley.
Newhaven is a working port town at the mouth of the River Ouse, with a cross-Channel ferry terminal, industrial estates, boatyards and warehouses alongside its homes. That makes it one of the more industrial places we cover in East Sussex: oil interceptors, gullies and yard drainage are a big part of our work here.
The town is on mains drainage, but low ground beside the river and the harbour drains slowly and some sites rely on pump stations. Up the valley, villages like Piddinghoe, South Heighton and Tarring Neville have homes on septic tanks and cesspits.
We’re SafeContractor, Achilles UVDB and RISQS approved, our crews work in East Sussex most days, and we answer the phone 24 hours a day.
Yards, depots, boatyards and car parks need oil interceptors and gullies emptied and cleaned to keep fuel, oil and silt out of the drains and the river. Our jet/vac tankers handle both, with waste transfer notes for every load.

We clear blocked drains at homes and businesses with high-pressure jetting and survey them with CCTV when they keep coming back.

Low-lying sites by the harbour and river often rely on pumps. We service them, test the pumps and alarms, and respond 24/7 when one fails.

In Piddinghoe, South Heighton, Tarring Neville and the farms along the lower Ouse, we empty septic tanks and cesspits and service treatment plants.

A port, a river mouth and the Downs behind.
Industrial and port sites with interceptors should keep records of inspections and emptying. Our waste transfer notes are part of that.
Land by the harbour and the Ouse drains slowly and can flood at high tide after heavy rain.
Villages up the valley are on chalk, which feeds drinking water. Septic tanks there must work properly.
