The Park Lands recreation value could be increased at the same time of innovatively managing Adelaide's catchment. A metropolitan water management system could be directed to the Park Lands which would have series of lakes and ponds to provide a natural filter before it goes to the Torrens. In addition to the "GAP" water this could be a great asset to the City. Torrens water could then be better managed through algae blooms and return to be used a key recreation facility. City of Salisbury was a world class innovator for water management, the City of Adelaide should partner with other Councils to be the next phase. Adelaide should be a world class leader in urban water management.
