A massive $271 million project at the WSSC Water facility in Accokeek, Maryland, is nearing completion. The first of two silos overlooking Piscataway Creek is now being filled up with biosolids — but you’re much more likely to call it all “poop.” And if you ride the bus in Montgomery County, it could help you get you where you need to go.

There are still a few things left to construct, but the process has started. Last week, WSSC Water went live with this major renewable energy project when it added microorganisms to the biosolids being held there. Those microorganisms are starting to break down the waste floating around inside and will eventually turn “poop into power.”
