InfoSewer Inflow Control for a Pump with a Pump Curve

Intoduction: InfoSewer is used worldwide by municipal engineers and planners to create detailed, accurate models of their sewer infrastructure systems. These models enable users to evaluate the effect of new developments, zoning changes, and other additional loads on system flows; pinpoint current and future problem areas; predict overflows and backups; and determine how to best restore needed capacity lost to infiltration and inflow with the least rehabilitation. In addition, users rely on these models to compute hydrogen sulfide generation and corrosion potential; analyze the rate of Biochemical Oxygen Demand (BOD) exertion; track sediment movement and deposition; calculate the amount of pollutant transported to the wastewater treatment plant; and assess pollutants’ impacts on receiving waters. Extensive scenario management along with domain and facility management functionality makes the program capable of analyzing existing or proposed sewage collection systems.  It has a Steady State, Design and EPS run modes and includes many of the same Arc Map tools that exist in InfoWater and InfoSWMM.

You can control the pumps in InfoSewer and H2OMap Sewer by using a Pump Control which will control the pump or pumps in your network based on:

  1. Volume
  2. Level
  3. Discharge
  4. Inflow
  5. Time

If you use a By Inflow control the pump speed of the pump is increased or decreased to make the Upstream Wet Well Level Constant (Figure 1) for an exponential 3 point curve

Figure 1. Inflow Control for PUMP in InfoSewer and H2OMAP Sewer will change the Pump Speed of the pump to make the Wet Well level constant

    1. InfoSewer By Discharge Control for a PUMP

       
      You can control the pumps in InfoSewer and H2OMap Sewer by using a Pump Control which will control the pump based on:
       
      1.       Volume
      2.      Level
      3.      Discharge
      4.      Inflow
      5.      Time
       
      If you use a By Discharge control the pump speed of the pump is increased or decreased to pump the incoming Wet Well flow based on the pump rules and the geometry of the Wet Well (Figure 1).
       

      Figure 1.  By Discharge Control for  PUMP in InfoSewer and H2OMAP Sewer will change the Pump Speed of the pump to follow the Base Pump Flow Rules.
