Blue Plains Advanced Wastewater Treatment Plant

DC Water operates the Blue Plains Advanced Wastewater Treatment Plant, the largest plant in the world. We provide wastewater collection and treatment services to more than two million Washington metro area customers. Our plant has the capacity to treat 370 million gallons of sewage a day. We embrace our mission to serve customers and sustain the environment.

The Blue Plains Advanced Wastewater Treatment Plant has been instrumental in protecting the environment since the beginning of plant operations in 1983. In 1996, DC Water assumed management of the Blue Plains Plant. The plant has received awards for peak performance from the National Association of Clean Water Agencies for more than 10 consecutive years, and in 2003, we received an excellence in management award.

Through our plant facility, DC Water has been a champion of protecting and restoring our waterways. In the last several years for example, the plant has dramatically upgraded and improved its liquid processing systems. As a partner to the Chesapeake Bay Agreement of 1987, the Blue Plains Advanced Wastewater Treatment Plant has taken a commanding role in improving the Potomac River and the Chesapeake Bay, and their watersheds. In addition, the plant's new biosolids program will help ensure that the facility's environmental commitment meets this century's demands.

We've gained an outstanding reputation both nationally and internationally as a result of our innovations and excellent record of compliance with federal regulations. Visitors from all over the world come to our plant to see our advanced research and engineering methods in action.
