Adelaide surface waterAdelaide StormwaterOn average, the Adelaide metropolitan area generates around 86 gigalitres of stormwater per year.
Stormwater is managed by Local Councils with some State Government input Much of this is discharged to the sea, with less than 10% currently being re-used.
Urban infill and associated increased density •Increases run off •Poses new problems when peak events occur

water is unproductive.
