The Future of DC's Water Starts Here

Pure Water DC is DC Water’s plan to make the District’s drinking water supply stronger and more reliable. Today, all of the District’s drinking water comes from the Potomac River and is treated at the Washington Aqueduct. If drought, pollution, equipment problems, or another emergency affects that supply, it could disrupt water service for many people.

Pure Water DC looks at practical ways to reduce that risk. The program includes protecting the Potomac River, improving how water moves through the system, adding more local storage. working with our regional partners, and studying advanced water recycling at our Blue Plains Water Resource Recovery Facility. The goal is simple: make sure DC Water has more than one way to keep safe drinking water flowing.

A key part of this work is the Pure Water DC Discovery Center. This center will test new treatment methods and show the public how used water can be cleaned so it is safe again. DC Water is also investing $21 million over three years to study options, test new ideas, work with regulators and share information with the public.

Why It Matters

The District depends on a steady supply of clean drinking water every day. DC Water serves more than 700,000 residents and millions of visitors each year, along with homes, schools, hospitals, businesses and federal buildings. A serious problem with the Potomac River or Washington Aqueduct could affect public health, daily life and the local economy.

Pure Water DC Discovery Center

DC Water broke ground on the Pure Water DC Discovery Center at Blue Plains on June 10, 2026.The facility will test advanced treatment technologies, collect information, and show how used water can be cleaned and reused safely. 

The center will give residents, students and community partners a simple way to learn more about Pure Water DC, how water recycling works, and why the need for a stronger water supply is critical to the District’s future. It is expected to open in 2027.

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.
