5 MDEQ Requirement 1. significant progress toward achieving the funding structure within 5 years 2. significant progress to mean the adoption of an initial rate increase to meet a minimum of 10 % of any gap in revenue needed to meet ex penses S.A.W. Significant progress toward ident ified funding structure

17 New Technology Improves the Process Verizon Mifi Jetpack Garmin GLO GoPro Camera Apple ipad Samsung Galaxy Tab S Envirosight Quickview Camera

18 Cloud Based Data Collection Options Uses a mobile app to collect data from any smart device Trimble cloud based application Cost per license: $250/user per year Best for Data collection Uses a mobile app to collect data from any smart device ESRI cloud based application Cost per license: Varies based on credits Best for project management and tracking

19 Operations Dashboard

20 Other Data Collection Options We can also collect the data using a client s existing asset management software application Data is collected using the software s app and saved directly to the database No merge required

21 Sewer Televising Approaches

22 Clean to Televise Televise to Clean Traditional method Provides clearer picture of interior Maintenance issues removed Better view of structural issues Assess current condition of pipe Identify maintenance issues Not all sewers require cleaning Structural issues still identifiable

23 Standard CCTV Contractor Standard PDF reports and videos Cleaning is an option More competitive SOLO robot Sewer Televising Source: RedZone Robotics -> Standard PDF reports and videos ICOM3 software Autonomous SOLO robots for 8-12 Sewer Multi-Sensor Inspection (MSI) technology Do not provide cleaning, but will partner with a cleaning contractor on an as-needed basis

24 Combines conventional qualitative CCTV with synchronized laser and sonar dimension information Provides a unique full 360 quantitative view of the pipeline Uses 3D LIDAR and SONAR data to generate a 3D model of the pipe and associated engineering reports Source: RedZone Robotics ->

31 Pipe factors: size, material Year installed Location Criticality factors Weights Assign depth, and condition (PACP rating)

32 Worst Condition Data Mining - Pipes In general, s built, large diameter (>18 ) RCP pipes appear to be in worst structural condition Consider inspecting other pipes with these characteristics 0 Best Condition 8 i n Pipe Diameter 36 i n Concrete Clay Reinforce d Concret e Unknown Asbestos Cement Vitrifie d Clay

33 Deterioration Curves New condition (Score 0) at installation Average score of manholes during 2015 inspection

34 Deterioration Curves Assets installed during 1940s degrade along this line

35 Deterioration Curves Different degradation rate for each decade

36 Deterioration Curves

37 Deterioration Curves Moving Average to Predict Future and degrade to End of Life

38 System Deterioration Curve In this community, we can expect manholes to last for an average of 110 years

39 System Deterioration Curve Current System Avg = 1.13

40 System Deterioration Curve ~50 years Rehabilitation Necessary when Structural Rating = 4

41 All the techniques (including deterioration & criticality) can be applied to vertical infrastructure o Treatment plants o Pumping Stations o Municipal Buildings

42 GIS: Best for data storage and presentation Data Accuracy: Include QA/QC procedures for updating GIS Establish unique IDs The End Product: Understand how the data being provided by contractors will be delivered.

43 Tools and Approaches: Various methods are being sold Only a portion of Asset Management Buyer beware Staff Involvement: Gain institutional knowledge Cooperation across department Engage water system departments

44 The Human Element Common sense validation Time Commitment: What does it really take

45 Asset Management is a lifestyle It is not a project with an end date To do Asset Management well, will take time It involves significant data requiring data management techniques Better tools are being develop to make better decisions When deciding on tools to use -- understand what you get
