2 Agenda 01 Introductions 02 InfoMaster Overview 03 Case Study 04 Q&A o Overview o Speaker Introduction A need for a different approach and what makes these tools distinctive o New Jersey American Water s System o Implementation of InfoMaster Question & Answer, summary, next steps, etc.

3 aging assets How much renewal does my utility really need? And when? utility planning challenges budgeting What s too much? What s too little? main breaks Why did the pipe fail? Was it planned to be replaced soon? rate increase How to justify rate increases to stakeholders? aging workforce Can we capture knowledge from retiring operations staff?

4 Traditional Capital Improvement Plans (CIPs) Challenges - Black Box not very defensible or repeatable - Hard to quickly decipher, visualize, and share the results - Difficult (time consuming and costly) to maintain

5 Living, breathing asset management & capital planning tool 02 ANALYTICS Proven Pipe Failure/Deterioration Analysis 01 DATA HUB Out-of-the-Box 100% GIS-Integrated built for Water/Sewer Utilities 04 REHAB ENGINE Robust Rehabilitation and Budgeting Engine 03 RISK ANALYSIS Defensible And Repeatable

6 Risk Analysis The Risk Analysis will associate a risk factor to each pipe in the network. The Risk Factor is normally defined as a combination of Likelihood of Failure and Consequence of Failure. Those can be related to different categories. Risk Class Extreme High Medium Low Negligible Capital Action High Priority in CIP / Yearly Operational Frequency Standard Priority in CIP / Biannual Operational Frequency Low Priority in CIP / 1 in 5 Years Operational Frequency 1 in 10 Years Operational Frequency Wait for a problem to arise

7 Risk Calculation

8 Failure Prediction Modeling

9 Failure Prediction Modeling

10 Valve Criticality Assessment Each valve analyzed individually Consequence of Failure rated by - No. valves needed to close - No. hydrants out of service - Length of main out of service - Quantity of demands out of service - Critical users out of service - Etc.

11 Valve Criticality Assessment

12 Rehabilitation & Budgeting Engine

13 InfoMaster Validation Process Installed & Trained / Provided Innovyze Feedback Engineers Determined Variables / Weights GIS Staff Developed Spatial Analysis & GIS Layers Iteratively Ran IM, Compared Results, Adjusted Model Shared & Collaborated on Final Results

14 Predecessor Work Flow Stepwise Variables

15 Predecessor Work Flow Stepwise Methodology Anyone See Problems? Operational Triggers (Quality, Fire Flow, Breaks, Pressure) Human Interpretation of Potential Project Areas Limited & Multiple Forms Defect / Consequence Data Limited Precise Location Data Data Entry Into Stepwise Comparison of Identified Projects

16 New InfoMaster Work Flow Bottoms Up! All Pipe GIS Analysis Single GIS format of input data Precise Location Data Objective, Defendable All-Pipe Ranking Human Collaboration & Planning

17 New InfoMaster Work Flow Variables

18 InfoMaster Work Flow Evaluate Cohorts along with Variables

19 Break Rates & the Problem of Very Small Numbers Solution - Add Kernal Density Scoring

20 InfoMaster Work Flow GIS Kernal Density Scoring AC Break Density Scores Segment Break Scores

21 Pro-Active, Interactive, Scientific, Defendable Main Replacement Tool
