Interceptors and gullies for the Lea valley’s industrial units, pump stations for Tottenham Hale’s new blocks, and drains for its homes.
Tottenham runs from the High Road east down to the River Lea, where industrial estates, warehouses and yards line the valley. Around Tottenham Hale, new towers have gone up beside the station and the Lee Valley Park. West of the High Road are long streets of Victorian and Edwardian terraces.
That gives us three kinds of work here: interceptors, gullies and yard drains on industrial sites; pump stations and plant rooms in new residential blocks; and blocked drains and surveys in the terraces. The High Road’s restaurants and takeaways need grease traps emptied too.
We’re SafeContractor, Achilles UVDB and RISQS approved, our crews work in north London most days, and we answer the phone 24 hours a day.
Warehouses, depots and yards along the Lea valley need interceptors emptied and gullies cleaned to keep oil and silt out of the drains and the river. Our jet/vac tankers handle both, with waste transfer notes for every load.
