REGIONAL WATER SUPPLIES
Noting that yesterday was World Water Day, I refer to the water shortages being experienced in rural and regional areas. (1) How many water tanker loads have been delivered to Walpole, when did the deliveries start, and when did they end? (2) Is this the result of poor water source management or poor water resource planning? (3) How many other towns have required water to be trucked in, which towns are involved, and when did this take place? (4) How is this related to the catastrophic collapse in stream flow resulting from rainfall decline and the changing south west climate? Hon KIM CHANCE

I thank the member for his concise, 10-point question without notice. In many schemes throughout Western Australia, carting of water is not unusual and is often the most sustainable short-term solution to maintain supply. Hon Paul Llewellyn interjected. Hon KIM CHANCE : Sorry, is that a supplementary question? The PRESIDENT : Hon Paul Llewellyn may ask another question next week. Hon KIM CHANCE : I continue my answer - (1) Six tanker loads or approximately 100 to 120 cubic metres of water a day have been delivered to Walpole. Deliveries started on 10 February 2007 and ended on 4 March 2007. (2) No. The problems in Walpole were due to poor winter rainfall. The Walpole supply had been alternating between Butlers Dam and the Walpole River. However, ongoing dry conditions resulted in the sources ceasing to flow with a resultant inability to meet the water demands during the first week of February 2007. Summer rainfall since early March has allowed carting to cease. The Walpole scheme is run on a strict operating strategy to maximise the water drawn from the two sources. A water supply planning review commenced last year and preliminary drilling enabled a ground water bore to be equipped last week to enable the Walpole water supply to be supplemented. However, the long-term water supply source planning is complex due to the conservation values of the area and the significant community consultation required. (3) Water was delivered to five towns over summer: Yarloop, Mullalyup, Northcliffe, Northampton and Yuna. Water has been trucked into Yarloop since 27 January 2007 to supplement the low flows in the source, which is Bancell Brook, but carting at Yarloop ceased last week. Water has been trucked into Mullalyup since 2 December 2007 and is ongoing. Water was trucked into Northcliffe for two weeks in February 2007 to supplement source flows from the spring, and water was also trucked into Northampton and Yuna to augment supplies during hot weather conditions over summer. (4) Carting in the south west and the mid-west regions has been due to a poor winter rainfall and very little summer rainfall, causing existing river sources and springs to dry out or to have reduced flows that are unable to meet the regular demand. Hence, in most cases, carting has been used to supplement the existing demand.

(1) How many water tanker loads have been delivered to Walpole, when did the deliveries start, and when did they end? (2) Is this the result of poor water source management or poor water resource planning? (3) How many other towns have required water to be trucked in, which towns are involved, and when did this take place? (4) How is this related to the catastrophic collapse in stream flow resulting from rainfall decline and the changing south west climate?

Deliveries started on 10 February 2007 and ended on 4 March 2007. (2) No. The problems in Walpole were due to poor winter rainfall. The Walpole supply had been alternating between Butlers Dam and the Walpole River. However, ongoing dry conditions resulted in the sources ceasing to flow with a resultant inability to meet the water demands during the first week of February 2007. Summer rainfall since early March has allowed carting to cease. The Walpole scheme is run on a strict operating strategy to maximise the water drawn from the two sources. A water supply planning review commenced last year and preliminary drilling enabled a ground water bore to be equipped last week to enable the Walpole water supply to be supplemented. However, the long-term water supply source planning is complex due to the conservation values of the area and the significant community consultation required. (3) Water was delivered to five towns over summer: Yarloop, Mullalyup, Northcliffe, Northampton and Yuna. Water has been trucked into Yarloop since 27 January 2007 to supplement the low flows in the source, which is Bancell Brook, but carting at Yarloop ceased last week. Water has been trucked into Mullalyup since 2 December 2007 and is ongoing. Water was trucked into Northcliffe for two weeks in February 2007 to supplement source flows from the spring, and water was also trucked into Northampton and Yuna to augment supplies during hot weather conditions over summer. (4) Carting in the south west and the mid-west regions has been due to a poor winter rainfall and very little summer rainfall, causing existing river sources and springs to dry out or to have reduced flows that are unable to meet the regular demand. Hence, in most cases, carting has been used to supplement the existing demand.
(2) Is this the result of poor water source management or poor water resource planning? (3) How many other towns have required water to be trucked in, which towns are involved, and when did this take place? (4) How is this related to the catastrophic collapse in stream flow resulting from rainfall decline and the changing south west climate? Hon KIM CHANCE replied: I thank the member for his concise, 10-point question without notice. In many schemes throughout Western Australia, carting of water is not unusual and is often the most sustainable short-term solution to maintain supply. Hon Paul Llewellyn interjected. Hon KIM CHANCE : Sorry, is that a supplementary question? The PRESIDENT : Hon Paul Llewellyn may ask another question next week. Hon KIM CHANCE : I continue my answer - (1) Six tanker loads or approximately 100 to 120 cubic metres of water a day have been delivered to Walpole.
