The default settings of Mermaid’s Evaluation Report shows the efficiency of the pumps of a lift station compared to the most efficient within this lift station. If you know that this new XYZ pump has an efficiency of x gallons per watt of electricity, then in the Cost area in the left pane of the Mermaid’s Evaluation Report analysis, set the “Compare with standard efficiency” to the efficiency of the new pumps. The Evaluation will update itself and show how many dollars per year could be saved using the new pumps.
