Implementation of Pressure and Leakage Management Strategies on the Gold Coast, Australia: Case Study

Many water authorities, both nationally and internationally, have been forced to rethink their strategies for achieving water balance as a result of growing water demands, droughts, reduced no-failure yields, and environmental sustainability considerations. In particular, regulatory bodies in Australia are demanding that water managers exhaust network management efficiencies before considering new water source options (e.g., dams, desalination, pipelines, etc.). Demand management incentive schemes in conjunction with water recycling and pressure and leakage management (PLM) initiatives are a few examples of least-cost planning strategies being adopted by water authorities to achieve water balance without expanding the water infrastructure asset requirements. Potential benefits of PLM strategies have been predicted by these authorities worldwide in areas such as deferred capital works, reduced corrective maintenance, reduced treatment costs, energy savings, reduced reclaimed water discharges, and improveme...
