Septic Tank Emptying in East Grinstead

Septic tanks and cesspits emptied for houses, farms and cottages in the High Weald countryside around East Grinstead.

Head out of East Grinstead in almost any direction and you’re soon in the High Weald National Landscape, a countryside of small fields, woods and steep little valleys. Many of the houses scattered through it, around Sharpthorne, West Hoathly, Kingscote and Hammerwood, rely on a septic tank or cesspit rather than a sewer. Some sit at the end of tracks that were never built with a tanker in mind.

The ground here changes fast. The Hastings Beds are layers of sandstone and clay stacked on top of each other, so one garden can drain freely while the next holds water like a pond. That has a big effect on how well a drainage field copes, and to how often the tank needs emptying. Two neighbours with the same size tank can need quite different schedules.

We choose a tanker sized for your lane, anything between 2,000 and 4,000 gallons. Every one carries jetting kit for the pipes. You get a waste transfer note for every load, and our office can ring you when it’s time for the next one.

What's included

How we empty your tank

A tidy job, start to finish, by our own crew.

  • Paperwork you can keep

    Your waste transfer note shows what was taken and where it went, which is useful when you sell or let the property.

  • A look before we start

    The operator checks the level and condition of the tank first, so anything unusual is spotted before the pump goes on.

  • A straight answer

    If we see a cracked wall, a missing baffle or a blocked outlet, we tell you plainly and explain what can be done.

  • Lids put back securely

    Covers are refitted and left safe, so there’s nothing for children, pets or livestock to fall into.

  • Tidy and careful

    Hoses are laid neatly and anything we spill is cleaned up before we leave.

  • Inlet and outlet cleared

    Every tanker carries jetting kit, so a blocked inlet or outlet pipe can be cleared on the same visit.

Frequency, price and access

Sandrock, clay and steep ghylls

Streams in this part of the Weald have cut deep, narrow valleys, known locally as ghylls, and many older cottages sit on their slopes. A drainage field on sloping ground can send liquid downhill faster than the soil can clean it, while a field laid on a band of clay may barely drain at all.

If you’re not sure what your tank drains into, or the field seems to be failing, a septic tank survey will give you the facts before you commit to any repairs. It’s also a sensible step if you’re buying a cottage out here.

Septic tank or cesspit?

A septic tank separates the solids and lets the liquid drain away to a soakaway or drainage field, so it only needs emptying when the sludge builds up. A cesspit is sealed and simply fills up, so it needs emptying far more often.

Questions answered

Septic tank emptying FAQs

Does the ground around East Grinstead suit drainage fields?

Sometimes. Where sandstone lies close to the surface, a field can drain well. Where there’s a band of Wadhurst Clay or Grinstead Clay, it can stay waterlogged for months. A percolation test tells you which you have before any new field goes in, and saves a lot of guesswork.

Can you empty my tank in an emergency?

Yes, we take emergency call-outs 24 hours a day, 365 days a year. Until we arrive, cut your water use right down: no baths, showers, washing machine or dishwasher, and flush as little as possible. Then call 03333 233566.

What is a waste transfer note?

It’s a record of what waste was taken, who took it and where it went. Householders have a duty to make sure their waste goes to a registered carrier, so keep the note we give you after every empty.

Are homes in the High Weald around East Grinstead on mains drainage?

The town and the bigger villages mostly are, but plenty of outlying houses, farms and cottages are not. Out towards Hammerwood, Kingscote and Sharpthorne it’s common to find a septic tank or cesspit. If you’re buying out there, ask the seller for any emptying records.

How big a tanker do you send?

Our tankers range from 2,000 to 4,000 gallons. We choose the size to suit your tank and the access, so tell us about narrow lanes or soft ground when you book.

Can I go on a regular schedule?

Yes. Many customers have their tank emptied on a set cycle, and our office gets in touch when the next one is due, so you don’t have to remember.
