D.C. Sewer Overflows

Update: Over on the Internet Archive you can check out a report by RBM on Washington, DC's fragile sewer system. The feature aired on NPR's Intern Edition. An excerpt from the intro:

Washington, D.C., is a wet place. In 1791, President George Washington chose a piece of marshland for the nation's capital. Two rivers and an oversized creek run through the District, which averages over 40 inches of rain per year. When storms drench city streets, parking lots and rooftops, millions of gallons of water rush through an aging network of pipelines that combine runoff with raw sewage. As Intern Edition's Raul Moreno reports, the Anacostia River is suffering from this polluted mixture, and city managers are trying to fix the problem.
