Leading Change in Australia: “Why best practice is destroying our waterways”
At the biannual conference held by Stormwater Australia, and titled Stormwater 2016: Rising to the Challenge, Rod Wiese presented the above paper. Rod is a champion for “doing business differently” in Australia and is playing a prominent role in leading change. The abstract for his paper is reproduced below
“This study explores the genuine desire to protect and enhance urban waterways through whole of water cycle measures having wide ranging benefits to community health and climate change resilience,” wrote Rod Wiese.
“Controls that recognise the value of enhancing the local waterways and imitating a more natural regime, namely recovery, re-use, infiltration and runoff control were investigated.”
“The options investigated were assessed against ‘Levels of Service’ (LoS) that represent the protection of local ecology, preservation of geomorphology and enhanced amenity for the community.”
“The LoS were achievement of a 60% stormwater volume reduction, representing moderate protection of waterways, and 90% volume reduction, being optimum protection.”
Base Cases & Overall Finding:
Three Base Cases were considered in the analysis:
- introducing local stormwater harvesting; and
- regional stormwater harvesting capturing a large catchment.
“The study found that the base cases were inadequate in achieving these LoS,” continued Rod Wiese. “Therefore we optimised these options to demonstrate the requirements that would need to be implemented to achieve the targets.”
