Mike,

Look into Philadelphia's Fairmount Waterworks, a National Historic 
Landmark as well as a National Historic Civil and Mechanical Engineering 
Landmark: 

http://www.fairmountwaterworks.org/
or
http://www.livingplaces.com/PA/Philadelphia_County/Philadelphia_City/Fairmount_Water_Works.html
or (via a New Jersey link)
http://www.state.nj.us/drbc/edweb/waterworks.htm

Besides a turbine, this waterworks provided the first municipal water 
supply in the US.
Good luck!
