Presentation Regional Transmission System Master Plan October 15, 2018 1
Everyone proposed offers specific expertise AND knowledge of your facilities. 2
This team will provide the precision analytics and deep, Broward-specific technical experience… Hazen’s precision Hazen’s deep Optimized, analytics Broward-specific operationally- experience realistic master plan for the future …to deliver the best answers for an operationally realistic Master Plan. 3
We consider this project to be two-fold: • Risk-based prioritization/ • Hydraulic modeling, interpretation of results: analyses and risk Best solution assessment (such as • Real budget likelihood and • Workable schedule • consequence of failure) Risk Analyses: Hydraulic Alternatives Risk-based CIP Data Pipes and Modeling Development Prioritization Pump Stations 4
zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA We will utilize two sets of tools for this project… Risk Analyses: Hydraulic Risk-based Alternatives CIP Data Pipes and Modeling Development Prioritization Pump Stations Flow Development – HazenQ Analytical Decision Previous Model and Support GIS Network Modeling Tools Tools Asset Condition As Built Drawings SCADA 5

For key pipelines, collection of additional data such as location of ARVs and high points, coupon samples, SmartBall results… zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA ..will increase the precision of the risk evaluation.

Additional testing of vertical assets will improve the accuracy of the condition scores. Risk Analyses: Alternatives Hydraulic Risk-based CIP Data Pipes and Modeling Development Prioritization Pump Stations 11
zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Testing results for pipelines and vertical assets will be incorporated into a condition assessment tool.. …and will be included in the risk prioritization analysis.

What is Surge or Transient • Fluctuations in flow and/or pressure, often sudden • Surge can result from any change in fluid velocity • Pumps: Startup, normal shutdown, trips • Valves: Opening, closing, or other operation • Air/Vacuum Valves: Opening and closing • Rapid Flow Changes: Pipe break, fire hydrant operation, customer demands, etc.
