The HRRP involves the remediation of river sediments affected by industrial activities of the former Newcastle Steelworks at Mayfield, New South Wales. Completion of works is scheduled for 2012.

Thiess Services has been involved with the project for over 12 months with early works dredging already undertaken. For the next phase of work, purpose-built facilities, on the former steelworks site, are being constructed to immobilise contaminants present in the sediments.

The material will then be encapsulated in specifically designed containment cells being constructed by Thiess Services on nearby Kooragang Island.

Thiess managing director, David Saxelby, said he was delighted that Thiess Services had been selected to undertake remediation works for a waterway that had such an important place in BHP Billiton’s and Australia’s industrial history.
