When operating in backwater conditions caused by a pump station wet well, flow monitoring data follow and iso-Q equal to the pumping capacity. This monitor is located upstream from a pump station that alternates between two lead pumps, each with a rated capacity of 9 MGD. The station has a total rated capacity of 16 MGD.
This scattergraph indicates that one lead pump is operating below capacity. However, the total capacity of the pump station exceeds its nominal rating. If needed, this pump station could be upgraded to a capacity of 23.5 MGD using the existing influent line.
