Improved measurement and data collection can lead to better information being available for planning, management, and operational decisions; engineering studies; and maintenance and troubleshooting. For example, if appropriate power monitoring is put in place at a WRRF, then data can be collected and used to evaluate the actual energy consumption of particular pieces of equipment or unit processes. Energy consumption data combined with operational data such as pressure and flow can be used to evaluate equipment efficiency and performance for a wide range of operating conditions. If the data indicate that the equipment is not operating at peak efficiency, this can help identify what the issues could be. For example, it could point to a degradation of equipment performance over time or that the equipment is being operated under condition changes that are less than optimal for the particular equipment. In many instances, minor operational or automation changes can improve energy efficiency or energy costs. Power monitoring should be evaluated so that metering, or submetering, is installed at the correct locations required to understand where energy is being consumed in the facility.
