Dr. Moussa Wone

Vice President, Clean Rivers Project

Dr. Moussa Wone is the Vice President for the Clean Rivers Project, also known as the Combined Sewer Overflow (CSO) Long Term Control Plan. Dr. Wone is responsible for implementing the project, which is designed to improve water quality in the District by controlling combined sewer overflows to our waterways. The project is one of the largest environmental projects in the District, spans 25-years and is federally mandated by a consent decree.

The Clean Rivers Project includes the planning, design, and construction of major infrastructure including a system of more than 18 miles of large tunnels along the Anacostia and Potomac Rivers, green infrastructure, targeted sewer separation, and a storage facility along Rock Creek. The CSO discharges captured by Clean Rivers infrastructure will be conveyed to the Blue Plains Advanced Wastewater Treatment Facility for treatment and discharge into the Potomac River.

That project was awarded the International Tunneling Association 2013 award for Technical Innovation of the Year, the 2016 ENR Best of the Best Project award and the 2016 DRB Dispute Avoidance Project award. During his tenure on the BPT, Dr. Wone oversaw the development of the durability requirements for the BPT structures that DC Water used as the technical justification basis for its 100-year Green Bond proceeds. Previously, Dr. Wone was the architect/engineer Owner Representative consultant for the Dulles Corridor Metro Rail Project. In this post, he was responsible for tunneling and tunnel systems program management support services for the Metropolitan Washington Airports Authority’s $2.9B, 11.7-mile, Phase-1 extension of the Washington Metro from West Falls Church through Tyson Corner to Dulles Airport.

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.
