EPA has an energy management benchmarking model called Portfolio Manager. This tool needs the following information to build an energy density number to benchmark your plant against:
Municipal Wastewater Treatment Plant
A wastewater treatment plant is a facility that is designed to treat municipal wastewater. The level of treatment at a plant will vary based on the BOD limits and the specific processes involved. This space type in Portfolio Manager is appropriate for primary, secondary, and advanced treatment facilities with or without nutrient removal. Treatment processes may include biological, chemical, and physical treatment. This space type is best applied to wastewater treatment facilities of 150 MGD or smaller. This space type does not apply to water treatment and distribution facilities.
The following information is required for wastewater treatment facilities:
Zip code
Average influent flow
Average influent biological oxygen demand (BOD5)
Average effluent biological oxygen demand (BOD5)
Plant design flow rate
Presence of fixed film trickle filtration process
Presence of nutrient removal process
