Bund cleaning removes accumulated liquid and residue from the containment around tanks and process equipment. We clean bunds when sludge obstructs inspection or rainwater reduces the space available for a spill. Water in a bund should not be assumed clean simply because the tank has no obvious leak.
Bund Cleaning
Bund cleaning to remove accumulated liquid and sludge, expose containment surfaces and identify visible defects for further inspection.

Bund contents and containment surfaces
The liquid can contain traces of the stored product, while heavier sediment collects at low points and around supports.
Recovery and access
Bund contents are identified and recovered without assuming a drain is an acceptable disposal route.
Bund contents and containment surfaces
The liquid can contain traces of the stored product, while heavier sediment collects at low points and around supports. We identify the contents before recovery and choose a method suited to the bund lining. Opening a drain valve is not the default disposal route. Sludge depth and access beneath pipework affect what can be removed.

Recovery, access and waste handling
We plan safe access around connected equipment, including any restricted-space hazards. The tank interior is a separate work area and is included only when agreed. Collected material is kept within an appropriate waste route, with checks for contamination before any discharge is considered. Washing must not damage protective coatings or seals.
Visible defects after cleaning
Cleaning can expose cracks, failed joints and active leaks. We explain those findings so integrity inspection or repair can follow. An emptied bund does not prove watertightness or adequate containment capacity.
Pipework and tank supports can prevent access to small sections of the bund floor. Any residue left behind those obstructions is identified separately from cleaned surfaces.
Bund Cleaning: common questions
Can rainwater in a bund be discharged automatically?
No. Contamination and the permitted disposal or discharge route must be established first.
Does bund cleaning include cleaning the tank inside it?
The tank interior is separate and is included only when agreed.
Will cleaning prove the bund will hold a spill?
No. Integrity and capacity need appropriate assessment beyond emptying and cleaning.
Why inspect below the liquid level?
Sludge can hide damaged joints or cracks that only become visible after cleaning.
Can the lining be damaged by cleaning?
An unsuitable chemical or aggressive method can harm it, so the lining informs method selection.
