pump wire-to-water efficiency, as well as operation and maintenance practices to improve efficiency, including periodic pump
efficiency testing. An accompanying Excel® tool helps utilities
evaluate different pump design and operational alternatives for
energy consumption, greenhouse gas emissions, and life cycle
cost. The tool allows the user to analyze either an existing pump
station or a new pump station. Figure 1 shows the progression
of steps in the tool.
Reducing Energy Demand and Cost
SINCE MUCH OF the energy demand of water utilities is for moving water, improving pumping system efficiency can reduce
demand and cost. Several Water Research Foundation (WRF)
research projects have uncovered different approaches utilities
can use to improve pumping station efficiency.

The goals of the Water Research Foundation’s Energy Focus Area, launched in 2012, are to improve energy efficiency at water and wastewater utilities, increase renewable nergy use, and identify opportunities for water/electric utility integrated planning.
