Commercial tank cleaning & decommissioningin Dorset

Britteco cleans, decommissions and removes commercial oil and fuel tanks across Dorset, from marinas and port businesses in Poole and Weymouth to dairy farms around Sherborne and Shaftesbury. We also inspect tanks over the county’s chalk and deliver emergency diesel when a site runs short.

Tank work in Dorset

Oilfield, harbour and chalk downland

Dorset has its own onshore oilfield. Wytch Farm sits on the shore of Poole Harbour, and a leak there in 2023 released around 200 barrels of fluid. It was a reminder of how sensitive the harbour is to oil, and the same applies to every smaller fuel store around its edge.

The Port of Poole, the marinas along the coast and the boatyards that serve them keep marine diesel and waste oil on site. Inland, the military ranges at Bovington and Lulworth hold fuel for vehicles and plant, and the dairy farms of the Blackmore Vale run tractors and generators on gas oil.

Oil heating is common in the rural west and north of the county, with 8.7% of households in the Dorset Council area relying on it alone in 2021. Older steel tanks on those properties and on farms are reaching the age where corrosion, leaks and sludge build-up become regular problems.

How we work in Dorset

Careful work near harbour and aquifer

In Dorset, containment comes first because both the harbour and the groundwater are easily harmed.

  1. Site check from photosWe look at where the tank sits relative to drains, the harbour edge or open ground. That decides how we lay out spill kits, hoses and temporary storage.
  2. Booked visit from BanburyWe fix the date in advance, and coastal sites with tide, marina or public access limits get an agreed arrival time.
  3. Contained pump-out and cleanFuel is transferred to sealed containers, then sludge and water are pumped out and the tank is cleaned and de-gassed. Nothing is drained to ground.
  4. Decommission, remove or refillThe tank is cut up and taken away, foam filled in place, or handed back clean and ready to use. Certificates follow for each outcome.

Rules & local risks

Chalk groundwater and a sensitive harbour

Dorset lies within the Environment Agency’s Wessex area. Much of the county stands on chalk, which stores groundwater and lets spilled oil soak down into it. Parts of Dorset also receive groundwater flood warnings, when the water table rises high enough to flood land and buildings from below and can lift or shift poorly secured tanks.

For any business storing more than 201 litres, the Control of Pollution (Oil Storage) (England) Regulations 2001 require secondary containment of at least 110% of the tank’s capacity. That covers marina fuel stores, farm tanks, IBCs and bowsers. GPP2 guidance explains how to site tanks away from drains, watercourses and open water.

When we finish, you have the records to prove it was done properly. Waste Transfer or Consignment Notes cover what we take away, and a Certificate of Disposal or degassing certificate covers the tank.

Questions

Dorset tank questions

Can you work at a marina or boatyard?

Yes. We plan access around moorings, tides and public areas, and keep all fuel and sludge in sealed containers. Waste oil from workshops and engine servicing can be collected on the same visit.

Why does the chalk matter for oil tanks?

Chalk lets liquids soak through quickly into the groundwater below. A leak that might stay on the surface elsewhere can travel further here, so bunds and fittings need to be in good condition.

What is groundwater flooding?

It happens when the water table rises and floods land from below, which parts of Dorset experience. Tanks in affected areas should be properly anchored and bunded, and we can inspect them and advise.

We are selling a commercial property with an old tank. What should we do?

Buyers and their solicitors usually want proof that a redundant tank has been dealt with. We can remove it or decommission it in place and issue the certificate you need for the sale.

How is a Dorset job arranged?

We check the site from your photos, then arrange a fixed date and arrival window, and the crew brings what is needed to finish in one visit. If a farm, yard or business runs low on fuel, diesel and heating oil can be delivered 24/7.
