We consider this project to be two-fold:

Hydraulic modeling,
Risk-based prioritization/

analyses and risk interpretation of results: assessment (such as

Best solution

likelihood and

Real budget

consequence of failure)

Workable schedule

For key pipelines, collection of additional data such as location

f ARVs and high points, coupon samples, SmartBall results…

..will increase the precision of the risk evaluation.

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.

Surge engine is under Run Manager Can easily switch from Standard, Fireflow analysis to Surge Can run a “hydraulic run only” under Surge Can start transient at anytime if you have an EPS run Can set global wave speed
