In parts of D.C., raw sewage flows into rivers and creeks when it rains. The city's Water And Sewer Authority is moving forward with a plan to fix the program.
D.C.'s sewer system is about 100 years old. It was designed to use rainwater to dilute sewage before running into local waters. But since then much of the District has been paved so there's not as much soil to absorb rain. And more people mean more sewage.
In response to a federal consent decree WASA is planning a series of underground tunnels to contain wastewater until it can be treated. WASA spokesman Carleton Ray says crews will break ground in May 2011, and the entire project will be finished by 2025.
