March 28th, 2018 DC Water will unveil the Clean Rivers Anacostia River Tunnel, a project that may well make the Anacostia safe to swim in again this year. The 2.4 mile long tunnel is 23 feet in diameter and will hold and transport combined sewage and stormwater runoff that has been pouring into the Anacostia River for decades, bringing the reduction since the consent decree to ~80%. When this piece of the Clean Rivers project starts to work, we anticipate an additional billion gallons of sewage and stormwater, annually, to stop polluting the Anacostia and instead be treated at Blue Plains after the storms have passed. Such a drastic reduction in sewage and runoff contamination into the river will hopefully produce an equally drastic improvement in water quality, especially in lowering the bacteria count, the reason the river is currently unsafe to swim in. By the time it’s warm enough to swim this year, we’ll know if it’s safe to do so, and so will you if you download the free SwimGuide app.
