Bilge water from vessels contains oil, fuel and other contaminants and must be disposed of by a licensed waste contractor — it cannot be discharged overboard or to surface drains. MacWaste provides bilge water collection from vessels, harbours and marinas across Northern Ireland.

Hazardous Waste Classification
The discharge of bilge water containing oil into harbour waters or coastal areas is prohibited under MARPOL and domestic marine pollution legislation. Vessels must use licensed reception facilities for bilge water disposal.
Collection to Suit You
MacWaste collects bilge water using vacuum tankers from harbour berths, marinas and boat yards across Northern Ireland, on a schedule that suits your vessel or operation — from a one-off collection to regular scheduled visits. We transport it to our licensed facilities for appropriate treatment and disposal.

Full Waste Transfer Documentation
We provide full waste transfer documentation for every bilge water collection — essential for vessels maintaining MARPOL Oil Record Books and for harbour authorities demonstrating compliance.
Combined with Other Services
Bilge water collection works best as part of our full marine waste package alongside Marine Oily Waste and Port & Harbour Waste Reception — one contractor, one set of paperwork, maximum convenience.
