Urban Developer Integrated Water Management From the sub-allotment to the subdivision

1. Urban DeveloperIntegrated Water ManagementFrom 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. Supporting Better Decision-making in Urban Water • 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

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?

5. What Does Offer? • Integration of modelling across the water cycle • Stormwater runoff generation  • Demand, end use and supply  • Waste water generation and re-use  • Stormwater constituent generation v1.0 • Stormwater constituent treatment v1.0 • Comparison and analysis at a range of scales  • A customisable and flexible modelling environment  • Productivity tools to aid model development  • Support for multi-replicate simulation v1 .0

6. With v0.4 Beta You Can...... • Build and modelling the existing water management infrastructure • stormwater • water supply • waster water • or even • a third pipe supply • Apply it to both greenfield and brownfield sites

7. With v0.4 Beta You Can...... • Explore management options at a range of scales • Allotment Impervious Area Tank Mains Supply In Roof Stormwater Out Water Use Node Waste Water Out

8. With v0.4 Beta You Can...... • Explore management options at a range of scales • Cluster

9. With v0.4 Beta You Can...... • Vertical integrated models to explore strategies at a range of scales • Link Scales Impervious Area Tank Mains Supply In Roof Stormwater Out Water Use Node Waste Water Out

10. Beyond 0.4.0 we will support… • Operation across a broader range of scales • Subdivision

11. Beyond 0.4.0 we will support… • MUSIC water quality modelling tools • The simulate water quality constituents • The exploration of stormwater quality treatment options

12. In Summary • Some of the key differentiating features of Urban Developer are the … • Integration of water quantity and quality across the entire water cycle; • Improved representation of urban demand and end use; • An ability to informatively link system operations across scales; and • Flexibility with respect to network configuration and definition.
