When a fuel or oil tank reaches the end of its service life, it must be safely decommissioned to prevent environmental pollution and comply with regulatory requirements. MacWaste provides tank decommissioning for both domestic heating oil tanks and commercial fuel storage tanks.

On-site tank decommissioning — emptied, cleaned and made safe before removal.
Domestic Oil Tanks
Redundant domestic heating oil tanks pose a risk of ground contamination if left in situ. We safely empty, clean and remove domestic oil tanks, disposing of the tank and residual waste in a compliant and environmentally responsible manner.
Commercial & Underground Tanks
Decommissioning of commercial and industrial fuel storage tanks — from petrol station underground tanks to bulk fuel storage — carried out in compliance with NIEA requirements and industry best practice.
How We Decommission a Tank
Isolate & Empty
The tank is isolated and all residual fuel or oil is safely removed.
Clean & Inspect
The tank is cleaned and checked to confirm it's safe to remove.
Remove & Dispose
The tank is removed from site and disposed of in line with NIEA requirements.

NIEA-Licensed & Fully Documented
Every decommissioning job is carried out to NIEA requirements, with full documentation provided for your compliance records.
Combined with Other Services
Tank decommissioning is usually preceded by tank & vessel cleaning to empty and clean the tank safely, and where the tank itself has recovery value we handle oil tank recycling as part of the same job — one contractor from first clean to final removal.
