🎯 Improving Pump Simulation in SWMM 5

 πŸŽ― Improving Pump Simulation in SWMM 5

  • Goal: Enhance the simulation of variable speed pumps in SWMM 5 for better accuracy.
  • Current Setup: πŸ”„ Users currently adjust three pumps (Pump1, Pump2, and Pump3) based on the depth in the Wet Well. This method relies on three distinct pump curves.
  • Proposed Solution: 🧠 Use SWMM 5's Real-Time Control (RTC) feature to simulate pump settings with a single control curve, streamlining the process.
  • How it Works:
    • πŸ“Š The pump flow is determined using the Pump Curve (refer to Figure 2).
    • πŸ› ️ This flow is then fine-tuned according to the Pump Setting (detailed in Figure 3).
    • πŸ’‘ Each pump operates with its unique control curve. These curves dictate when the pump activates or deactivates based on the Wet Well's depth (Check Figures 4, 5, and 6 for the respective pumps).
  • Benefits: 🌊 This method ensures a more consistent flow (visualized in Figures 7 and 8). Moreover, it offers flexibility to simulate varying pump speeds using a singular pump curve, depending on the active pump.

Conclusion: πŸš€ Utilizing the RTC feature in SWMM 5 paves the way for a more precise and streamlined simulation of variable speed pumps with just one foundational pump curve.
