QuestionView source ↗
I refer to the pressure reduction trials in Rossmoyne, Shelley and Waterman that were able to achieve significant savings of water akin to additional supply costed at between 12 cents and 74 cents a kilolitre, and I ask -
(1) Given the significant water savings that can be gained cheaply through a roll-out of network optimisation – pressure reduction trials, what progressive roll-out has the Water Corporation devised for this program?
(2) In line with the recommendations from the Water Corporation network optimisation final report released August 2009, when will the State of Western Australia see the rapid deployment of pressure regulation in suitable areas in the water reticulation network?

(1) The results of the pressure management trials show that they were a success, with a total reduction in water supplied of 13.5%, 11.9% and 18.9% for Waterford, Shelley and Rossmoyne respectively. This outcome was achieved while continuing to provide essential services to the communities involved. Following these trials a comprehensive planning study has been completed which has identified and prioritised those parts of Perth where pressure management could potentially be implemented.
(2) Based on the findings of the planning study, the prioritisation and allocation of capital funding is currently being considered in the compiling of the Water Corporation's future Capital Investment Program. A broader roll-out of pressure management program will involve significant capital investment as well as on-going operating expenses to maintain the infrastructure required. Both the timing and the rate of implementing a pressure management program for Perth are included in these considerations.
