Like you, we are learning today about EPA’s announced proposal to modify the Lead and Copper Rule to require water systems across the country to replace lead service lines within 10 years of the effective rule. Given an anticipated effective date of 2027, this would translate into the removal of all lead service lines by 2037. EPA is also proposing additional changes, including lowering the lead action level.
(Washington, DC) – DC Water CEO and General Manager David L. Gadis today joined U.S. EPA Deputy Assistant Administrator Mae Wu, Congresswoman Eleanor Holmes Norton, and other District and Federal officials to celebrate the commissioning of the Northeast Boundary Tunnel (NEBT). The five-mile-long tunnel is the final component of the Anacostia River Tunnel System which will reduce combined sewer overflows to the Anacostia River by 98 percent in an average year, significantly improving water quality in the river. The NEBT will also mitigate flooding in many District neighborhoods where flooding has been a chronic issue during intense rainstorms.
This week, the DC Water Board of Directors approved a design-build contract for construction of the Potomac River Tunnel (PRT). The $819 million contract is the largest ever awarded by the Authority. The 5.5-mile-long tunnel will control combined sewer overflows (CSOs) to the Potomac River, improving water quality in this critical natural resource. This work is part of the larger Clean Rivers Project, a $2.99 billion program to improve the water quality of the Anacostia and Potomac rivers and Rock Creek by increasing the capacity of the sewer system.
