CBNA, Halmar win $819M Potomac River Tunnel contract

Oct 17, 2023

Both construction firms expect to begin work next year and complete the 5.5-mile-long tunnel in early 2030. Published Oct. 17, 2023 Award: Potomac River Tunnel Client: District of Columbia Water and Sewer Authority The District of Columbia Water and Sewer Authority’s board of directors approved a $819 million design-build contract earlier this month for the construction of the Potomac River Tunnel , the largest ever awarded by the authority, according to a press release. The 5.5-mile-long tunnel aims to control sewer overflows into the Potomac River and forms part of the $2.99 billion Clean Rivers Project, an initiative to improve area water quality. The joint venture of Miami-based CBNA and Nanuet, New York-based Halmar International will build the 18-foot diameter tunnel, which will run beneath the Georgetown waterfront in Washington, D.C., and connect to the existing Anacostia River Tunnel. The CBNA and Halmar team expect to begin work on the project in 2024, with completion in early 2030, according to the release. Construction will require two tunnel boring machines: one will mine south through mostly soft ground and the other will head north to bore through rock. Once operational, the Potomac River Tunnel will reduce combined sewer overflows to the Potomac River by 93% in an average year of rainfall, according to DC Water. That will be a major achievement for the overall Clean Rivers Project, said David Gadis, DC Water CEO and general manager. “The Clean Rivers Project is a gamechanger for the district,” said Gadis. “We have already seen the impact the completed Anacostia River tunnel system is having on the health of that river, and we expect similar results for the Potomac as a result of this project.” The Clean Rivers Project is DC Water’s ongoing program to reduce combined sewer overflows into the district’s waterways, namely the Anacostia River, Potomac River and Rock Creek. The project is a massive infrastructure and support program designed to capture and clean wastewater during rainfalls before it reaches those rivers. Recommended Reading

Peregrine Power

Peregrine Power is a company that received a SBIR Phase I grant for a project entitled: Universal Utility/Customer Interface. Their research project will lead to an electrical panel with modules that provide interfaces between the electrical grid and the residential customer's on-site loads and other energy systems. Through the use of interactive solid state meters, the utility will be able to intelligently regulate loads and dispatch on-site energy systems. The on-site energy systems include, but are not limited to, controlled loads (e.g., water heating), pluggable EVs, generation systems (e.g., PV panels), and energy storage (e.g., spent EV batteries). The panel and modules represent the most integrated and economic system attempted so far to enable more intelligent energy management and will encourage renewable energy and conservation. In addition, new grid stabilization opportunities will be created for the utility. The proposed approach will use advanced power electronics, along with state-of-the-art communications techniques. The broader impacts of this research are (1) to enable utilities and over 50,000,000 residential customers to implement safe, convenient and economic energy management techniques, (2) to encourage renewable energy, and (3) to provide distributed generation and storage systems that assist the utility in stabilizing the grid. This would lead to more reliable and less costly energy for the customer, along with reduced greenhouse gas.
