Wastewater Tank Cleaning

Removing settled wastewater residues safely and properly

What looks like a simple dirty-water tank can easily involve scum layers, heavy settled solids, fibrous build-up and awkward internal deposits. The method has to reflect the actual condition inside the tank rather than what the outside of the asset suggests.

We assess the wastewater stream, the state of the residue, access constraints and the next stage of work before starting. That might mean making the tank ready for engineers, restoring working volume, or cleaning it so the wider treatment system can keep operating without the same level of restriction.

If the removed material has to leave site as controlled waste, it still needs to be transferred in line with GOV.UK hazardous waste guidance. Where the tank contents are more chemically affected, our contaminated waste disposal service may also be relevant.
