Pump Controls in InfoSewer and H2OMAP Sewer

Water Pump

Five ways to control the pump by controls in InfoSewer and H2OMAP Sewer. Here are a few examples and important features of the various InfoSewer Pump Controls. A pump in InfoSewer and H2OMAP Sewer uses a Newton-Raphson iteration process for 50 iterations or until the successive iterations between pump flows are 0.001 cfs.

  • By Volume – control the pump by the pump volume (cubic feet or cubic meters). The on and off settings, pump curve and the iteration process applying to pumps are the controlling simulation features.
  • By Level – control the pump by the pump level or depth ( feet or meters). The on and off settings, pump curve and the iteration process applying to pumps are the controlling simulation features.
  • By Discharge – control the pump by the pump pattern in flow units. The pump pattern (discharge), pump curve and the iteration process applying to pumps are the controlling simulation features. The pump speed adjusts to main the pump pattern.
  • By Inflow – control the pump by the inflow to the Wet Well. The Wet Well inflow, the iteration process applying to pumps are the controlling simulation features. The pump flow equals the inflow to the Wet Well and the Wet Well stays at a constant level.
  • By Time – control the pump by the time speed pattern. The pump curve is used when the pump is turned on by the pattern.

The Wet Well inflow, the iteration process applying to pumps are the controlling simulation features. The pump flow equals the inflow to the Wet Well and the Wet Well stays at a constant level.

Figure 5.  Pumps controlled by Inflow, Wet Well is constant and the Pump Speed changes to pump the inflow to the Wet Well.  By Time – control the pump by the time speed pattern. The pump curve is used when the pump is turned on by the pattern.
