Water Company Uses Flow to Make Electricity from the Pittsburgh
Post-Gazette
"Taking its cue from the Municipal Authority of Westmoreland County, the Pennsylvania American Water Co. has turned a problem into a benefit by going with the flow, literally. The high pressure of raw water flowing from two reservoirs into the Oneida Valley Water Treatment Plant in Summit Township, Butler County, initially prompted PAWC to install a butterfly valve to crimp the flow into the plant. High water pressure can burst a pipe. But company officials soon realized that crimping the pipe with a valve was one big waste of renewable energy."
