GROUNDWATER SUPPLIES - NORTH METROPOLITAN REGION
With regard to groundwater resources, I ask the minister - (1) What is the current status of plans and projects to develop alternative groundwater supplies from the following sources in the north metropolitan region - (a) Eglinton; (b) Pinjar; (c) Barragoon; (d) Yanchep; and (e) Karnup? (2) How much water is planned to be extracted annually from the sources identified in (1)? (3) In July 2006, Marsden Jacob Associates Pty Ltd completed an analysis of the economic value of the Gnangara mound groundwater in Western Australia for the Department of Water. Will the minister table the report? (4) How many metres has the groundwater dropped in the Gnangara mound since commencement of water extraction? Hon KIM CHANCE

I thank the honourable member for some notice of this question. The answer to part (4) of the question is by about three metres. However, it is a very long answer and quite detailed, Mr President, so I will table the answer and seek leave for its incorporation in Hansard . Leave granted. [See paper 2610.] The following material was incorporated - (1) All these groundwater projects were previously identified as potential groundwater sources in the Water Corporation’s Integrated Water Supply System Source Development Timetable 2001-2031 . However, due to uncertainty regarding future available groundwater allocation, plans for expansion of the existing scheme at Pinjar and development of the Barragoon scheme were excluded from the Water Corporation’s current Integrated Water Supply Scheme Source Development Plan 2005 . (a) Conceptual planning exists for development of superficial and Leederville aquifer bores below urban development in the north-west corridor. Investigations to develop more detailed plans are currently programmed to commence in 2009/10. (b) No current plan for expansion. (c) No current plan for development. (d) Conceptual planning completed to replace the existing local scheme with development of new superficial and Leederville aquifer bores below urban development in the north-west corridor. Development of the new Yanchep scheme is unlikely to be required before 2025. (e) Conceptual planning exists for a combined Karnup-Dandalup groundwater project of superficial and Leederville aquifer bores. There are no plans for development within the next 15 years. (2) For the period from 1 July 2006 to 30 June 2007, the following are the figures: (a) Eglinton - none. (b) Pinjar - 20.08 gigalitres comprised of 6.30, 8.03 and 5.75 gigalitres from the Superficial, Leederville and Yarragadee aquifers respectively. (c) Barragoon - none. (d) Yanchep - 1 gigalitre. (e) Karnup - none. (3) Following receipt of the draft report in July 2006, the Department of Water (DoW) requested that Marsden Jacob Associates extend the scope of the original study. This additional work has been incorporated into a final report which is currently being assessed by DoW staff prior to being released to the public. (4) The first monitoring bores were installed on the Gnangara mound in the 1960’s. Since 1979, the maximum water level decline has been 6.3m in monitoring bore PM16 near Lake Pinjar on the crest of the Mound. The individual effects of climate change, pine plantation and groundwater abstraction have resulted in approximately a maximum 3m decline each in different locations on the Mound.

(b) Pinjar - 20.08 gigalitres comprised of 6.30, 8.03 and 5.75 gigalitres from the Superficial, Leederville and Yarragadee aquifers respectively. (c) Barragoon - none. (d) Yanchep - 1 gigalitre. (e) Karnup - none. (3) Following receipt of the draft report in July 2006, the Department of Water (DoW) requested that Marsden Jacob Associates extend the scope of the original study.

(4) The first monitoring bores were installed on the Gnangara mound in the 1960’s. Since 1979, the maximum water level decline has been 6.3m in monitoring bore PM16 near Lake Pinjar on the crest of the Mound. The individual effects of climate change, pine plantation and groundwater abstraction have resulted in approximately a maximum 3m decline each in different locations on the Mound.
I thank the honourable member for some notice of this question. The answer to part (4) of the question is by about three metres. However, it is a very long answer and quite detailed, Mr President, so I will table the answer and seek leave for its incorporation in Hansard . Leave granted. [See paper 2610.] The following material was incorporated - (1) All these groundwater projects were previously identified as potential groundwater sources in the Water Corporation’s Integrated Water Supply System Source Development Timetable 2001-2031 . However, due to uncertainty regarding future available groundwater allocation, plans for expansion of the existing scheme at Pinjar and development of the Barragoon scheme were excluded from the Water Corporation’s current Integrated Water Supply Scheme Source Development Plan 2005 . (a) Conceptual planning exists for development of superficial and Leederville aquifer bores below urban development in the north-west corridor. Investigations to develop more detailed plans are currently programmed to commence in 2009/10. (b) No current plan for expansion. (c) No current plan for development. (d) Conceptual planning completed to replace the existing local scheme with development of new superficial and Leederville aquifer bores below urban development in the north-west corridor. Development of the new Yanchep scheme is unlikely to be required before 2025.
