Affordable Passive Treatment for Small Sewage Treatment Systems

Here's an interesting story from Anthony Watts of Watts Up With That fame, the best blog on the web for climate change information.  Many small publicly-owned treatment works (POTWs) in West Virginia are too small to install active wastewater treatment, which can be expensive to build and operate.  In order to help those  POTWs  meet environmental requirements for treating sewage, Fred Jaeger is marketing the Poo-Gloo.   It is a dome-shaped device that increases the surface area on which bacteria can break down sewage and other pollutants. It's much more affordable than active treatment, and about as effective.
