The future is under construction in Accokeek, Maryland, and it's being built by WSSC Water.

The future is taking shape in Accokeek, Maryland, in the form of a cutting-edge water treatment and green energy project. WSSC Water is transforming the way the Piscataway Water Resource Recovery Facility will handle waste from five existing water resource recovery facilities. The Piscataway Bioenergy Project - the largest and most technically advanced project ever constructed by WSSC Water - will use innovative technology to recover resources and produce green energy. In the coming years, the Piscataway plant will evolve into a bioenergy production facility that uses efficiency, technology and sustainability to enhance the region's environmental and financial health. This $271 million project is expected to serve our customers for the next 100 years.

The Piscataway Bioenergy Project will transform how WSSC Water manages biosolids - the nutrient-rich organic materials produced by the wastewater treatment process - from five existing water resource recovery facilities. Using cutting-edge technology, the new facility will significantly reduce the amount of biosolids produced, thus reducing costs to haul and manage the product. The Bioenergy Facility will provide superior biosolids treatment to produce an exceptional quality (EQ), Class A material that can be marketed and distributed as soil conditioner and fertilizer. With the transition to a Class A product, WSSC Water will also eliminate the need for lime addition, currently used for Class B treatment, further reducing biosolids hauling and chemical costs. 

The Piscataway Bioenergy facility is expected to be substantially complete by November 2024.
