DC Water part of Water Research Foundation Team Awarded $1 million Grant by EPA for Exciting New Wastewater Innovation

October 19, 2020

DC Water announced today that it is partnering with Water Research Foundation, Hampton Roads Sanitation District and several universities on groundbreaking new research that will save customers money and could improve water quality.

The goal is improved wastewater treatment and DC Water’s concept for improving the technology has the potential to save millions for cities around the world, said Chief Executive Officer and General Manager David L. Gadis.

“Our goal is to reduce energy and chemical use and save our customers money while using innovative technology to improve the environment,” explained Mr. Gadis, while praising the partnership with Water Research Foundation, Hampton Roads Sanitation District, George Washington University, Northwestern University and Columbia University.

The U.S. Environmental Protection Agency awarded the collaboration team its ‘Science to Achieve Results grant’ with a three-year timeframe for achieving results. At DC Water, the project is led by Haydee De Clippeleir, the research program manager and Christine deBarbadillo, the director of clean water quality and technology.

deBarbadillo said the Authority has worked closely with all members of this collaboration team for many years exploring solutions and upgrades to existing wastewater treatment processes. Removing nitrogen is a critical element in DC Water’s requirement to clean wastewater to the highest possible level before discharging it back into the Potomac River, where it leads to the Bay.

Discharge of excess nitrogen and phosphorus can lead to algal blooms in surface waters. When that happens, the health of marine life, from fish to crabs to dolphins, is jeopardized.

The typical treatment methods used at water resource recovery facilities to eliminate nitrogen rely on addition of readily degradable organic chemicals such as methanol as well as consuming a tremendous amount of electricity.

“We are using a different pathway into the nitrogen cycle to more efficiently remove nitrogen from wastewater and reduce energy and chemical costs,” deBarbadillo said.

There is no active spill or overflow. Work to strengthen the pipe to begin soon.

Today, DC Water completed construction on a temporary bypass system as part of sewer repairs on the Potomac Interceptor near Pennyfield Lock in Potomac, Maryland. Crews turned on the pumps and successfully tested the system. With the bypass now ready, it will allow us to begin the emergency repairs inside the pipe by carrying the wastewater around the repair area.

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.

Starting the week of July 13, 2026, people who live, work or travel near the Canal Road NW entrance to Georgetown University may hear controlled blasting. This work is part of our Potomac River Tunnel Project.

When blasting happens, neighbors may hear a brief noise or feel light shaking. Drivers, cyclists, and pedestrians on Canal Road NW may also be stopped for a few minutes while we safely complete each blast.
