DC Water CEO to Serve on President Biden’s National Infrastructure Advisory Council

September 08, 2022

WASHINGTON, DC — DC Water announced today that CEO and General Manager David L. Gadis has been named to the National Infrastructure Advisory Council (NIAC). Mr. Gadis will serve with distinction as the sole expert on the Council from the wastewater utilities sector, among more than two dozen new appointments that included industry leaders from transportation, energy, and defense.

Mr. David Gadis said, “I am deeply honored to receive the appointment to NIAC at such a critical time, while national attention is so firmly fixed on infrastructure solutions. President Biden has committed unprecedented resources to fixing these issues. We can’t overemphasize the outstanding necessity of the Infrastructure Act, which invests more than 1.2 trillion in restoring and improving our roads, electricity grid, and access to broadband. However, with its dual commitment to clean water and Great Lakes and rivers restoration, our aging wastewater utilities must also receive ample consideration and funding.”

As CEO of DC Water, David Gadis oversees a $1 billion annual budget, a workforce of approximately 1,200 employees, and the largest Advanced Wastewater Treatment Plant in the world that provides services for nearly 700,000 District residents. 

Gadis continued, “In my role with DC Water, I have a unique vantage point to help inform NIAC. The challenges facing wastewater utilities are not insurmountable, and we have tackled many complex policy issues. In my new capacity on NIAC, I am excited to shine a light on wastewater utilities as an integral part of infrastructure.”

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.
