  1. SAME2012 SA/SC Joint Engineer Training SymposiumOctober 2-4, 2012 GIS & Hydraulic Modeling for Water / Sewer Asset Management and Rehabilitation Planning Keith D. Hodsden, Sr., P.E. Client Service Manager

  2. Innovyze Oveview • Subsidiary of MWH Global • MWH Soft / Wallingford Software Merger • Company Renamed in March 2011 • Same Market Leading Products, Services, Support • Corporate HQ: Denver, CO • Operations HQ: Pasadena, CA • Global offices with local focus • US Offices in Every Time Zone • Experienced software support

  3. US Infrastructure Situation • Aging Infrastructure • Infrastructure design life is 50 to 80 yrs • Out of sight = out of mind • EPA: $170 to 493 Billion in next 20 years* • Congressional Budget Office: $245 to $424 Billion* • Water Infrastructure Network: $420 Billion* • Limited funds = need to prioritize • Military bases arguably worse • “Ostrich” Consideration * EPA 816-R-05-001 Drinking Water Infrastructure Needs Survey & Assessment – 3rd Report to Congress, June 2005

  4. Current Situation* • 2009 – WSSC had 1,847 water breaks • 611 breaks in January 2009 • 240,000 water main breaks/year in USA • Large utility breaks in the Midwest increased from 250/yr to 2,200/yr over 19 years • Baltimore, MD had 1,190 main breaks in 2003 • more than 3 per day • British study in 2005 correlated diarrhea with low water pressure events (including main breaks) • USGS estimates 1.7 trillion gallons of water lost in the US per year, at a cost of $2.6 Billion * EPA Aging Water Infrastructure Research Program: EPA/600/F-07/015, September, 2007

  5. Historical Infrastructure Needs

  6. Sample Deterioration Curve Pipes do not deteriorate at a constant rate • Variables: • Material • Soil condition • Wrapping/Lining • External Loading • Excavation Activity • Corrosion Protection • Pipe Depth • Pipe Pressure • …

  7. What Has Been Done? • Engineering firms develop one-off, proprietary solutions (excel, access, GIS, etc.) • Difficult for clients to use / limited training • No upgrade path • No $$ vehicle for updates • Original author(s) may leave, be promoted, or otherwise unavailable

  8. Asset and Data Management

  9. Asset Management & Rehabilitation Planning

  10. CapPlan Water Overview • Risk-based capital planning tool for water distribution systems • Incorporates hydraulic model, GIS, CMMS data in one platform for analysis • Allows for proactive capital plans • Builds an asset management model

  11. Risk-Based Planning Represents a New Focus for Most Utilities Historical Approach to Renewal Planning Risk-Based Renewal Planning

  12. CapPlan Work Flow Diagram Consequence of Failure Multiple Calculation Options Likelihood of Failure Calculation of Risk Rehabilitation Engine Rehabilitation Costs Budget Scenarios Prioritized Capital Plan

  13. Likelihood of Failure W1L1 P1+W2L2 P2+…+WmLm Pm • Hydraulic Condition (Pressure, Flow, & Velocity) • Infrastructure/Asset Data (Age, Material, Dia.) • Soil Characteristics • Seismic Faults • Railroad Intersection • Traffic • Defect History • Joint Type • Others

  14. Consequence of Failure W1C1 P1+W2C2 P2+…+WmCm Pm • Flow (Demand) Supplied • Population Density Served • Critical Facilities Served • Outage/Isolation Analysis • Traffic • Others

  15. Outage/Isolation Analysis • Evaluate each pipe

  16. Outage/Isolation Analysis • Evaluate each pipe • ID u/s pipes/valves

  17. Outage/Isolation Analysis • Evaluate each pipe • ID u/s pipes/valves • ID d/s pipes/valves

  18. Outage/Isolation Analysis • Evaluate each pipe • ID u/s valves • ID d/s valves • Remove elements

  19. Outage/Isolation Analysis • Evaluate each pipe • ID u/s valves • ID d/s valves • Remove elements • Find pressure problems No Water Pressure Low Water Pressure

  20. Outage/Isolation Analysis • Evaluate each pipe • ID u/s valves • ID d/s valves • Remove elements • Find pressure problems • Evaluate fire flow

  21. Flexible Risk Classification

  22. Calculate Risk • Linear (Likelihood X Consequence) • Bi-directional matrix • Multi-criterion classification • Likelihood X Consequence is normalized between 0 and 1. • For each consequence definition, lower and upper boundaries can be set to define Low, Medium and High risk.

  23. Each Asset Mapped to Risk Matrix

  24. Rehab Costing and Phasing • Define Rehabilitation Costs • Define Rehabilitation Actions • Establish Phasing & Budget • View Reports or Maps

  25. Energy Optimization & Sustainability

  26. Energy Management Calculating/Projecting Pump Energy Use Determine total pumping costs based on actual energy cost charges Calculate energy cost for operating pumps under various demand conditions

  27. Pump Scheduler Optimal Pump Scheduling Optimize pump scheduling to minimize energy cost Set constraints for system pressure, tank level, pipe velocity, water age, etc

  28. Sustainability Reduce Power Costs & Carbon Footprint Quickly determine carbon footprint and total energy losses across entire water system Visualize specific pipes, pumps, valves, and taps with the highest carbon footprint
