On August 10, the Maryland Board of Public Works approved a $104-million grant from the state’s Bay Restoration Fund to help the Blue Plains Advanced Wastewater Treatment plant pay for a $950-million project to improve the plant’s nitrogen-removal technology and capacity. According to DC Water (http://www.dcwater.com/), which operates Blue Plains, the plant is the largest wastewater-treatment plant in the world, with a capacity of 370 million gallons per day. It provides wastewater treatment for the District of Columbia as well as parts of Virginia and Maryland.
