13 Future trends in water infrastructure planning Darko Joksimovic, Ryerson University TBD, WaterTAP Vladimir Nikolic, Ryerson University

14 What do we need to consider in UWS planning? Regulations and incentives for green approaches - green roofs to green streets

15 What do we need to consider in UWS planning? Regulations and incentives for green approaches rebates and education

16 What do we need to consider in UWS planning? Regulations and incentives for reuse

17 What do we need to consider in UWS planning? Regulations and incentives for reuse New development projects of 250,000 square feet or more of gross floor area are required to install and operate an onsite non-potable water system to treat and reuse available graywater, rainwater, and foundation drainage for toilet and urinal flushing and irrigation, and New development projects of 40,000 square feet or more of gross floor area are required to prepare water budget calculations.

18 What do we need to consider in UWS planning? Technological changes User behavior / demand Smart homes and appliances Advanced building systems IofT, Remote monitoring and control

19 What do we need to consider in UWS planning? Integration with land use planning and other systems water pathway

20 What do we need to consider in UWS planning? Integration with land use planning and other systems material pathway

21 What do we need to consider in UWS planning? Integration with land use planning and other systems energy pathway

22 What do we need to consider in UWS planning? Integration with land use planning and other systems energy pathway Source: Meggers and Leibundgut, The potential of wastewater heat and exergy: Decentralized high-temperature recovery with a heat pump, Energy and Buildings, 43 (4), 2011

23 What do we need to consider in UWS planning? Sustainable communities planning Systems approach Future user demands, buildings, landscape, technologies, drivers and objectives Integration with Legacy (centralized) systems Other infrastructure Pressures Urban growth Climate change

24 Urban Metabolism

25 Urban Water Metabolism Traditional (Linear) Approach

26 Urban Water Metabolism Alternative Approach

27 Integrated Urban Water Management (IUWM) Use of Alternative Sources of Water Hybrid Water Services Systems

28 Decentralized Solutions - Examples City of Philadelphia Land-Based Green Programs City of San Francisco Water Reuse Program

29 Hybrid Water Services Systems Cost of infrastructure for long distance transport and treatment 1. Spatial and Temporal Variability More efficient use of resources 2. Energy and GHG Intensity 6. Economic Viability Improving service security Hybrid Water, Storm and Wastewater System Reducing system failure risks 3. Downstream Impacts 5. Social Aspects Strengthening local economies Regenerating and protecting the natural environment 4. Legal and Institional Fortifying community wellbeing Potential Benefits VS Complex Interactions

30 IUWM and Water Metabolism Models

31 Integrated Water Resource Evaluation Tool (IWRET) The current project will develop an urban water metabolism model that allows: Interaction between all components of urban water cycle; Modeling of factors that change with time (demand, demographics, land use, system configuration and capacity, etc.) Representation of existing water infrastructure and new technologies; Integral representation of environmental and socio-economic dimensions; Explicit representation of spatial characteristics and temporal scales; Flexibility for broad stakeholder adoption in decision making

34 Your Turn - Options to Include in IWRET

35 Getting the feedback for IWRET development Session 3

36 Assessment of Alternatives (1) Capital Environmental Economic Indicator Indicator Unit Chemical use Energy use Reductions in energy use Water usage Water loss Savings in potable consumption Savings in non-potable consumption Savings in wastewater generation Total rainfall runoff Reductions in rainfall runoff Improvements in runoff quality CO2 caused, avoided CH4 caused, avoided NO2 caused, avoided Life cycle costs Total cost of building materials used Willingness to pay Affordability Financial risk exposure Capital cost Operational cost liters kwh kwh m3 m3 m3 m3 m3 m3 m3 % m3 m3 m3 $ $ $ $

37 Assessment of Alternatives (2) Capital Social Technical Indicator Potential risk to human health Number of trees / plantings planted on site Area of land devoted to parks and open spaces Percentage of land devoted to parks and open spaces Number of permanent jobs created Public acceptability Participation/responsibility Public awareness Social inclusion Performance Maturity Ease of demonstration Reliability Durability Flexibility/adaptability Indicator Unit 1-5 # m2 m2 #

38 IWRET Platform, Graphical User Interface (GUI) and Workshop Summary Session 4

39 Graphical User Interface (Option 1) Example: WERF Model Spatially lumped model Series of forms and questions Excel Based
