 Traditional urban and industrial development alters landscapes from permeable vegetated surfaces to a series of impervious interconnected surfaces resulting in large quantities of stormwater runoff, requiring management.Historically Australia, like other industrialised countries including the United States and United Kingdom, has treated stormwater runoff as a liability and nuisance endangering human health and property.This resulted in a strong focus on the design of stormwater management systems that rapidly convey stormwater runoff directly to streams with little or no focus on ecosystem preservation.
