Worsley Alumina Raising Bauxite Residue Disposal Areas
WBHO-I is delivering construction services on South32’s bauxite mining and alumina refinery operations in WA. The programmed raising of selected BRDAs have been planned to meet the requirements of the BRDA mud deposition plan, to allow mud deposition to continue as planned by the company. The principal component of WBHO-I’s works involves continuous lifts across their embankments, with the type of raise varying from upstream raise, downstream raise or centreline raise determined by client.
