(Fri., June 29, 2012) – Mayor Peter Carlisle today announced that the City has launched its first renewable wastewater energy project, which is expected to save more than $15 million in electricity costs over 15 years.

“This is a great example of an innovative green energy project that makes solid sense for our community,”

The City estimates that the project will reduce the plant’s electricity purchase needs by 5,500,000 kilowatt hours or 69 percent of the its current power consumption.
