(a-b) Planning for all services and requirements for the mine is ongoing and is coordinated through the Southdown Working Group, chaired by the Great Southern Development Commission. The Department of Water (DoW) and the Water Corporation (Corporation) are members of this group. The mine's present proposal is to self supply some 10-12 gigalitres (GL) per year using seawater desalinisation. The mine has detailed plans for this option, has undertaken some initial consultation and advised it will be submitting a formal proposal to the Environmental Protection Authority in the near future.
The mine is also proposing to utilise groundwater in the Redmond - King river area northwest of Albany, and has undertaken studies in consultation with the DoW to assess the impact of this abstraction. The mine has submitted applications to construct the groundwater bores, and anticipates applying for a licence to abstract 1-2 GL by the end of the year. In addition, the mine has discussed with the Corporation the use of the Corporation's effluent wastewater for use in the pipeline carrying the magnetite to the port.
(c) The potable water supply at Wellstead is presently at capacity and an expansion of this service is required. The Corporation is presently reviewing the available options to increase this supply.
