Transient Surge Analysis for 13-km Wastewater Pipeline from STP
A transient surge study is required for a 13-km pipeline transporting treated wastewater from a sewage treatment plant (STP). The study aims to predict critical pressure extremes and identify necessary hardware locations for protection before commissioning. It will model the pipeline's geometry and flow data, simulate pump operations, valve maneuvers, and power failures, and assess pressure envelopes and risks. Deliverables include a calculation report, marked-up General Arrangement Drawing (GAD), and a summary of components.

A transient surge study is needed for a 13-km buried pipeline carrying treated wastewater from an STP. The study will model the pipeline's existing geometry, elevations, and flow data. Simulations will cover pump start/stop sequences, planned valve maneuvers, and full power-failure scenarios.
The analysis will identify pressure extremes, vapor pocket risks, and column separation zones. Deliverables include a calculation report with model details, a marked-up General Arrangement Drawing (GAD) showing the recommended locations for valves and other devices, and a summary sheet with component specifications. Tools such as Bentley HAMMER, AFT Impulse, or Flowmaster may be used for the analysis.
