Cleaning DC’s Waterways
From an interesting editorial in the Washington Post on Sunday December 8th, 2012:
“ONE OF THE District’s largest environmental projects planned for coming decades is a system to prevent a noxious mixture of urban runoff and raw sewage from flowing into Rock Creek and the Anacostia and Potomac rivers every time there is a big storm. As The Post’s Darryl Fears reported last week, a legally binding agreement requires the D.C. Water and Sewer Authority to construct, at a cost of $2.6 billion, three huge tunnels into which this filthy water could be stored until treatment. But everyone in government seems to agree the city might be better served by a different approach: investing in “green infrastructure” that absorbs rainwater — things such as retention pools and grass rooftops. These have the potential not only to project local rivers but also to improve the city’s air quality and provide buildings with added insulation.”
