This one-hour webinar will be presented live at noon Central Time on Thursday, Jan. 17, 2013, after which a video recording will be available at sCityNetwork.com/webinars.

Treating wastewater is extremely energy intensive, making up 30-60% of a city's energy bill when combined with energy used for drinking water treatment.

A mere 10 percent reduction could save millions!

This webinar will explore how wastewater treatment facilities in two Midwestern cities - Davenport, Iowa, and Fort Wayne, Ind. - have traversed the long and winding road toward energy independence. From upgrades to aeration systems, through the introduction of anaerobic digestion and into the harvesting of "high-strength wastes" that supercharge methane generation, these communities have shown that facilities once considered energy hogs are now beginning to reverse electric meters at a faster pace than ever.

Laurie Twitchell, senior project manager at FOX Engineering, will explain how Davenport's plant went from spending $900,000 a year on power 35 years ago, to receiving a net credit back from its power company in recent years as a result of the power it saves and generates. The facility's total energy usage has been cut in half, and its natural gas usage has been reduced by 95 percent.

Ben Groeneweg, manager of the Utility Asset Management & Sustainability program for the city of Fort Wayne will describe what his community has been doing to reduce energy consumption, boost energy generation and identify new local energy sources. He'll explain how the collection of fats, oils and greases (FOG) from local restaurants and industrial plants can be a rich source of "food" for methane-producing bacteria that can supplement sanitary sewer waste in municipal digesters, producing valuable energy while preventing FOG from clogging sewer pipes and treatment plant equipment.
