O&M Energy Efficiency Checklist

for Wastewater Treatment Plants


The purpose of this list is to help identify no cost or low cost electricity savings through operation and maintenance practices at wastewater treatment plants.  The list is organized by System (blower aeration, mechanical aeration, mixing, pumping, etc) in approximate order from highest to lowest energy use.  Therefore, start at the top of the list and work down.  Because some measures are common to multiple systems, they are repeated, so that each system has a complete list.  Please review “Other Measures” on last page, which lists important ideas applicable to the entire plant.


Please distribute this open source document to anyone who might be interested, and please provide comments, suggestions, and new ideas to Walt Mintkeski, P.E., at, 503-771-0232, in Portland, Oregon.
