Water Supply Options – Water Mains Through Docklands Stormwater Drain Sewer Main

Potable Substitution 438ml/y D2 - Under investigation - Sewer Mining Sewer mining

D2 – Under Investigation - Stormwater Harvesting Stormwater Harvesting Potable Substitution 268ml/y

D2 - Stormwater Harvesting and Reuse Project • Investigation in partnership with City West Water • Sub-surface storage: 10ML • Treatment capacity: ~ 750 kL/day • Local capture and use of rainwater & stormwater will continue

Next steps • Second Decade of Docklands consultation process in 2010 • Stakeholder engagement eg: • City of Melbourne • Melbourne Water • Regulators (Department of Health etc.) • Further investigation of viability of trigeneration at scale • Stormwater Harvesting concept plan confirmation and functional design
