The first 12 Rotarians to sign up will meet at 5000 Overlook Avenue SW, Washington, DC 20032 to tour: The Largest Advanced Wastewater Treatment Plant in the World!

DC Water’s Blue Plains Advanced Wastewater Treatment Plant is the largest plant of its kind in the world. On an average day, the facility treats close to 300 million gallons of wastewater and has the ability to treat over 1 billion gallons a day at peak flow. Wastewater flows in from the District of Columbia and from Montgomery and Prince George’s Counties in Maryland and Fairfax and Loudoun counties in Virginia.

The plant opened as a primary treatment facility in 1937. Since that time, new processes and technologies have been added to provide advanced wastewater treatment. The Blue Plains facility now uses both primary and secondary treatment as well as denitrification, multimedia filtration and chlorination/dechlorination during the treatment process.

At DC Water, they believe wastewater is more than just waste. During the treatment process, useful products like biosolids and energy are extracted to be reused. They land apply their biosolids across the region, recycling nitrogen and phosphorous back into local soils. The thermal hydrolysis process used in their digesters generates about 10 megawatts of electricity that they reuse to cut their electricity consumption by a third. These efforts help to continue to improve their treatment process and remain a leader in sustainability for the future.
