Western Environmental was engaged by the primary contractor to design, construct, operate and maintain a groundwater “capture and contain” remediation system comprising a 480 m groundwater dewatering array and multi-stage treatment system to adjust pH, remove suspended solids, metals and a range of organic contaminants that were mobilised as a result of ground improvement works to augment stadium construction. Abstracted water was successfully treated and subsequently re-used during construction, thereby avoiding off-site discharge or disposal.
During subsequent phases of the project, Western Environmental were engaged client-side as expert advisors in relation to contamination and ASS management and were responsible for contractor oversight, review of consultant and contractor reports/plans and documents, auditing of contractor performance for compliance with project documentation and regulatory guidelines, and preparation of project close-out reports.
