Enviropacific was engaged by Laing O’Rourke Australia to perform civil construction works for the partial upgrade of fire infrastructure at Royal Australian Air Force Base, Amberley.
Enviropacific was engaged to construct 2km of firemain (and connections) while managing PFAS impacted waste soil, water and sludge generated.
The work involved bulk excavation, placement, and reinstatement of 2km of 500mm diameter firemain (pipework installed by others), producing over 13,000 tonnes of PFAS impacted soil for offsite disposal to an approved waste disposal facility.
Protection of critical underground infrastructure was vital throughout the work.
The management of NDD Sludge throughout the project was completed onsite through lined sludge ponds for mixing and drying prior to disposal to licenced landfill.
The contaminated water was processed by an onsite Mobile Water Treatment Plant (MWTP), achieve results significantly below the discharge criteria.
In total over 790,000 litres of PFAS impacted water was treated with nil exceedances of Defence guidelines.
- 13,000 tonnes of PFAS impacted soil removed
- 790,000 litres of PFAS impacted water treated onsite
- Water treatment results significantly below discharge criteria
- 2km of 500mm diameter firemain installed
