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.”

Efforts to isolate the damaged section of pipe are moving forward. Engineers are on site and preparations are underway to permanently install a steel bulkhead gate that will cut off flow to the collapse site in combination with an enhanced bypass pumping system that will continue to divert wastewater around the failure and into the Potomac Interceptor further downstream. Once fully activated, the system will allow contractors to begin stabilizing the area around the break and initiate excavation down to the damaged pipe and rock dam.
