Sewage Pump Size Calculator


The Sewage Pump Size Calculator is a valuable tool for individuals and professionals involved in sewage system planning. This calculator helps you identify the optimal pump size based on the specific requirements of your sewage system, ensuring efficient and effective operation.


To calculate the required pump size, the Sewage Pump Size Calculator uses the formula: Required Pump Size = Total Flow / Pump Cycle Time. This formula ensures that the pump has the capacity to handle the sewage flow efficiently.

How to Use

  1. Total Flow (Gallons per Minute): Enter the total flow of sewage in gallons per minute that your system needs to handle.
  2. Pump Cycle Time (Minutes): Enter the pump cycle time, which represents the duration of each pumping cycle.
  3. Click the “Calculate” button to obtain the required pump size in gallons per minute.


For instance, if your sewage system handles a total flow of 120 gallons per minute and the pump cycle time is 10 minutes, input these values into the calculator. The result will provide the required pump size to efficiently handle the sewage flow.


  1. Q: Is the Sewage Pump Size Calculator suitable for residential use?
    • A: Yes, the calculator can be used for both residential and commercial sewage systems.
  2. Q: Can I use this calculator for industrial sewage systems?
    • A: Absolutely, the calculator is designed to assist in sizing pumps for various sewage system applications, including industrial settings.
  3. Q: What units should I use for Total Flow and Pump Cycle Time?
    • A: Enter the values in gallons per minute for Total Flow and minutes for Pump Cycle Time.
  4. Q: Does the calculator take into account peak sewage flow periods?
    • A: No, the calculator provides a general estimate based on average flow conditions. For systems with significant peak flows, additional considerations may be needed.
  5. Q: Is the Sewage Pump Size Calculator applicable to both submersible and non-submersible pumps?
    • A: Yes, the calculator is suitable for sizing both submersible and non-submersible sewage pumps.


Optimize the performance of your sewage system by using the Sewage Pump Size Calculator. Properly sizing the pump ensures reliable and efficient sewage handling, preventing issues such as backups and overflows. Incorporate this calculator into your planning process to achieve optimal results in sewage system design and operation.
