• 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

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?

Tools for Integrated Water Management

• 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

What Does Offer?

• 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

• MUSIC water quality modelling tools

• The simulate water quality constituents

• The exploration of stormwater quality treatment options

Beyond 0.4.0 we will support…

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.
