(1) Yes. The Rottnest Island Authority (RIA) has commenced a project to upgrade the Waste Water Treatment Plant (WWTP) to provide a design more suited to the conditions on the Island, and to provide higher quality waste water, and a free source of irrigation for the Island.
(2) The use of bore and desalinated water is tightly regulated and the RIA will continue to comply with the current and any future licence conditions. In renegotiating the licence this year, the RIA is seeking to increase extraction from the saline beach bores and substantially reduce extraction from the shallow aquifer.
(3) Initially the irrigation of the golf course will be achieved with stored rainwater and desalinated water, supplemented if needed with a small demand (less than 13% of the current licence allowance) on the shallow aquifer to reduce costs.
(a) $115 000.
(b) Approximately $220 000.
(c) $214 355.
