Energy Conservation Measures at WWTPs

Jim Newton, P.E., DEE

Providing reliable wastewater services is a highly energy intensive activity. A report by the Electric Power Research Institute in 1996 estimated that water and wastewater treatment would reach 75 billion kilowatt hours in 1996. It is considerably higher at this time. In fact, the Consortium for Energy Efficiency now estimates the electric usage at closer to 100 billion kilowatt hours and at a cost of $.075 per kWh, total costs for electric usage is near $7.5 billion per year. It is of growing importance to wastewater utilities and the public who pay for these services to finds ways to reduce these costs. The US EPA has just released a report titled “Evaluation of Energy Conservation Measures for Wastewater Treatment Facilities”, EPA 832-R-10-005, September 2010, which will serve as the text for this course. The course will also review successful case studies demonstrating the basic concepts.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
