We Recycle Nutrients

DC Water's Blue Plains Advanced Wastewater Treatment Plant serves more than two million customers in the District, Virginia and Maryland and treats 384 million gallons of raw sewage on an average day.

One valuable product of wastewater treatment is what industry professionals refer to as biosolids. Biosolids are nutrient-rich organic materials produced from the treatment of sewage. When treated and processed, they can be recycled and used as a soil amendment to improve and maintain the soil on farms and gardens to help plants grow. Biosolids recycling protects the Chesapeake Bay by keeping nutrients like nitrogen and phosphorous out of local waterways. It also helps local farmers by saving them money in fertilizer costs.

Nutrient Management

The Maryland Department of Environment and the Virginia Department of Environmental Quality regulate and control the application of biosolids to land. Biosolids applicators carefully develop nutrient management plans for each site and submit their plans to their state agency for approval. These plans determine how biosolids are applied to each site.

A Winning Strategy for You and the Environment

DC Water is proud of our biosolids recycling program. To assist in this effort, DC Water has contracted with Maryland Environmental Service, an independent state agency specializing in water and wastewater treatment. MES provides support for our field inspection programs and public education efforts. Their staff provides the public with information about analyses of biosolids produced at the DC Water facility, quality assurance issues, contractor information and the delivery of material to our sponsoring sites. For more information, call 1-800-4RECYCLE, Monday through Friday, 8 a.m. to 4 p.m.

We invite you to learn more about DC Water's Biosolids Recycling Program. Please contact Chris Peot at 202-787-4329.

DC Water Breaks Ground on Piney Branch Tunnel, Final Phase of DC Clean Rivers Project

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.
