We are back to that silly scenario again. The PRESIDENT : Order! I am sure someone will answer the question if the Leader of the Opposition asks it. Hon NORMAN MOORE : Somebody will speak, Mr President. Whether someone provides an answer is another question. I refer the minister to the Water Corporation’s plans for future water supply development from traditional sources, and ask - (1) What is the estimated cost and time required for developing - (a) Gingin groundwater supply; (b) Eglington groundwater supply; and (c) Yanchep groundwater supply? (2) What is the estimated cost and time required for developing the Brunswick surface water supply? (3) What is the estimated cost and time required for proceeding with arrangements to obtain an additional 17 gigalitres from Wellington Dam? Hon JON FORD
AnswerView source ↗
I thank the honourable member for some notice of this question. The Minister Assisting the Minister for Water Resources has provided an answer. It is quite detailed and lengthy and I seek leave to have it incorporated in Hansard . [Leave granted.] The following material was incorporated - I thank the Hon. Member for some notice of this question. 1. (a) The estimated capital cost for developing the Gingin groundwater supply is $439 million. Additional costs may be incurred to integrate Gingin water into the Integrated Water Supply Scheme. The Gingin groundwater system is physically complex and competition for the resource is relatively high. It is therefore estimated that it would take intensive effort and between five and ten years to secure access to this groundwater resource. 1. (b) The estimated cost for developing the Eglinton groundwater supply is $54 million. Additional costs may be incurred to integrate Eglinton water into the Integrated Water Supply Scheme. The Department of Environment is currently reviewing statutory water level criteria and the sustainable groundwater abstraction amounts from the Gnangara Mound under Section 46 of the Environmental Protection Act (1986). The review, which is ongoing at present, is likely to have implications for the proposed Eglinton groundwater supply hence the timing of this supply cannot be specified at the current time. Subject to the outcomes of the review, an estimated five years (minimum) would be required to develop this supply option. It is anticipated that the timing for development of the Eglinton groundwater supply will be driven by local land development pressures in the North West corridor, as opposed to the “global” water balance of the Integrated Water Supply Scheme as a whole. 1. (c) The estimated cost for developing the Yanchep groundwater supply is $33 million. Additional costs may be incurred to integrate Yanchep water into the Integrated Water Supply Scheme. The Department of Environment is currently reviewing statutory water level criteria and the sustainable groundwater abstraction amounts from the Gnangara Mound under Section 46 of the Environmental Protection Act (1986). The review, which is ongoing at present, is likely to have implications for the proposed Yanchep groundwater supply hence the timing of this scheme cannot be specified at current time. Subject to the outcomes of the review, an estimated five years (minimum) would be required to develop this supply option. It is anticipated that the timing for development of the Yanchep groundwater supply will be driven by local land development pressures in the North West corridor, as opposed to the “global” water balance of the Integrated Water Supply Scheme as a whole. 2. The estimated cost for developing the Brunswick surface water supply option is $275 million. Additional costs may be incurred to integrate Brunswick water into the Integrated Water Supply Scheme. Significant lead times will be required to resolve allocation related issues (eg. environmental, social) associated with the Brunswick surface water supply option. It is estimated that up to five years would be required to complete regulatory approval processes, plus three years to construct the Brunswick scheme. 3. The estimated cost for proceeding with the Wellington Dam Pumpback (providing 12 GL for the Integrated Water Supply Scheme and 5 GL for local industry) is $87 million. Additional costs may be incurred to upgrade the bulk water transfer infrastructure necessary to integrate water into the scheme. The timing of the Wellington pumpback supply option is dependent on resolution of issues associated with ensuring appropriate water quality for use as a potable supply. It is estimated that development of the Wellington pumpback option would take two to three years.

It is estimated that development of the Wellington pumpback option would take two to three years.
1. (a) The estimated capital cost for developing the Gingin groundwater supply is $439 million. Additional costs may be incurred to integrate Gingin water into the Integrated Water Supply Scheme. The Gingin groundwater system is physically complex and competition for the resource is relatively high. It is therefore estimated that it would take intensive effort and between five and ten years to secure access to this groundwater resource. 1. (b) The estimated cost for developing the Eglinton groundwater supply is $54 million. Additional costs may be incurred to integrate Eglinton water into the Integrated Water Supply Scheme. The Department of Environment is currently reviewing statutory water level criteria and the sustainable groundwater abstraction amounts from the Gnangara Mound under Section 46 of the Environmental Protection Act (1986). The review, which is ongoing at present, is likely to have implications for the proposed Eglinton groundwater supply hence the timing of this supply cannot be specified at the current time. Subject to the outcomes of the review, an estimated five years (minimum) would be required to develop this supply option. It is anticipated that the timing for development of the Eglinton groundwater supply will be driven by local land development pressures in the North West corridor, as opposed to the “global” water balance of the Integrated Water Supply Scheme as a whole. 1. (c) The estimated cost for developing the Yanchep groundwater supply is $33 million. Additional costs may be incurred to integrate Yanchep water into the Integrated Water Supply Scheme. The Department of Environment is currently reviewing statutory water level criteria and the sustainable groundwater abstraction amounts from the Gnangara Mound under Section 46 of the Environmental Protection Act (1986).

The estimated cost for developing the Brunswick surface water supply option is $275 million. Additional costs may be incurred to integrate Brunswick water into the Integrated Water Supply Scheme. Significant lead times will be required to resolve allocation related issues (eg. environmental, social) associated with the Brunswick surface water supply option. It is estimated that up to five years would be required to complete regulatory approval processes, plus three years to construct the Brunswick scheme. 3. The estimated cost for proceeding with the Wellington Dam Pumpback (providing 12 GL for the Integrated Water Supply Scheme and 5 GL for local industry) is $87 million. Additional costs may be incurred to upgrade the bulk water transfer infrastructure necessary to integrate water into the scheme. The timing of the Wellington pumpback supply option is dependent on resolution of issues associated with ensuring appropriate water quality for use as a potable supply.

The PRESIDENT : Order! I am sure someone will answer the question if the Leader of the Opposition asks it. Hon NORMAN MOORE : Somebody will speak, Mr President. Whether someone provides an answer is another question. I refer the minister to the Water Corporation’s plans for future water supply development from traditional sources, and ask - (1) What is the estimated cost and time required for developing - (a) Gingin groundwater supply; (b) Eglington groundwater supply; and (c) Yanchep groundwater supply? (2) What is the estimated cost and time required for developing the Brunswick surface water supply? (3) What is the estimated cost and time required for proceeding with arrangements to obtain an additional 17 gigalitres from Wellington Dam? Hon JON FORD replied: I thank the honourable member for some notice of this question. The Minister Assisting the Minister for Water Resources has provided an answer. It is quite detailed and lengthy and I seek leave to have it incorporated in Hansard . [Leave granted.] The following material was incorporated - I thank the Hon.

(b) The estimated cost for developing the Eglinton groundwater supply is $54 million. Additional costs may be incurred to integrate Eglinton water into the Integrated Water Supply Scheme. The Department of Environment is currently reviewing statutory water level criteria and the sustainable groundwater abstraction amounts from the Gnangara Mound under Section 46 of the Environmental Protection Act (1986). The review, which is ongoing at present, is likely to have implications for the proposed Eglinton groundwater supply hence the timing of this supply cannot be specified at the current time. Subject to the outcomes of the review, an estimated five years (minimum) would be required to develop this supply option. It is anticipated that the timing for development of the Eglinton groundwater supply will be driven by local land development pressures in the North West corridor, as opposed to the “global” water balance of the Integrated Water Supply Scheme as a whole. 1. (c) The estimated cost for developing the Yanchep groundwater supply is $33 million. Additional costs may be incurred to integrate Yanchep water into the Integrated Water Supply Scheme. The Department of Environment is currently reviewing statutory water level criteria and the sustainable groundwater abstraction amounts from the Gnangara Mound under Section 46 of the Environmental Protection Act (1986).

The estimated cost for developing the Brunswick surface water supply option is $275 million. Additional costs may be incurred to integrate Brunswick water into the Integrated Water Supply Scheme. Significant lead times will be required to resolve allocation related issues (eg. environmental, social) associated with the Brunswick surface water supply option. It is estimated that up to five years would be required to complete regulatory approval processes, plus three years to construct the Brunswick scheme. 3. The estimated cost for proceeding with the Wellington Dam Pumpback (providing 12 GL for the Integrated Water Supply Scheme and 5 GL for local industry) is $87 million. Additional costs may be incurred to upgrade the bulk water transfer infrastructure necessary to integrate water into the scheme. The timing of the Wellington pumpback supply option is dependent on resolution of issues associated with ensuring appropriate water quality for use as a potable supply. It is estimated that development of the Wellington pumpback option would take two to three years.
The following material was incorporated - I thank the Hon. Member for some notice of this question. 1. (a) The estimated capital cost for developing the Gingin groundwater supply is $439 million. Additional costs may be incurred to integrate Gingin water into the Integrated Water Supply Scheme.
