1. Urban Developer Integrated Water Management From the sub-allotment to the subdivision eWater Road Show 21 Feb – Part 4 of 5 Dr Matthew Hardy Environmental Engineer, BMT WBM Urban Product Leader, eWater

2. Policy frameworks and decisions are becoming increasingly complex Regulators are encouraging alternatives options… …and more efficient use of water resources Increased stakeholder engagement further complicates decision making processes Solutions emphasise integrated or total water cycle management for purpose of water sensitive urban design Supporting Better Decision-making in Urban Water

3. More Precisely Some of the Decisions Faced Are Design Decision – What infrastructure will meet strormwater peak flow reduction and detention requirements? meet stormwater quality improvement targets? reduce consumptions of mains supply? decrease runoff days to local streams? maximise developable land…..? Policy Decisions – Which management options should we invest in to meet out mains water consumption targets, at what scale? reduce ecological impacts of urban development on our catchment? improve local and regional water security? increase the longevity of our existing infrastructure?
