Interceptors, gullies and pump stations for Dartford’s business and logistics sites, and drains and septic tanks for homes around it.
Dartford sits by the Thames at the Kent end of the Dartford Crossing, surrounded by logistics sites, retail parks, business estates and fast-growing new neighbourhoods at Ebbsfleet, Greenhithe and Swanscombe. That makes it one of the busiest places we cover for commercial drainage: interceptors, gullies, pump stations and yard drains.
New housing often relies on pump stations managed by residents’ companies. Older parts of the town have clay drains that crack and block. Up the Darent valley, villages such as Sutton-at-Hone, Horton Kirby, South Darenth and Farningham have homes on septic tanks and treatment plants.
We’re SafeContractor, Achilles UVDB and RISQS approved, our crews work in Kent most days, and we answer the phone 24 hours a day.
Warehouses, depots, retail parks and car parks need interceptors emptied and gullies cleaned. Our jet/vac tankers handle both, with waste transfer notes for your environmental records.

We service pump stations for management companies and businesses, test the pumps, floats and alarms, clean the wet well and respond 24/7 when one fails.

Logistics, new estates and a river valley.
Large yards and car parks need interceptors inspected and emptied regularly, with records kept.
Homes at Ebbsfleet, Greenhithe and Swanscombe may drain to private pump stations. Check who’s responsible.
Villages up the valley sit on chalk that supplies drinking water, so tanks must work properly.

★★★★★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!
