  • 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
