I wish WEF would set up a used equipment exchange for the water and wastewater industry, but they have not. As I travel around the country, I see a lot of equipment sitting idle, often viewed by the owners as a liability, rather than the asset it could be. I"m interested in brokering this equipment. We can often find a centrifuge to match what you have, for 25% of the price of a new one. Look on the WEF website for a paper we gave at WEFTEC 2007, about one municipality that sole two surplus centrifuge to two other municipalities.
