D.C. Water Management
But now, the three-tunnel solution is in doubt, and activists, engineers and bureaucrats are arguing once again about the best path to cleaner waters. Although digging is underway for the first tunnel, D.C. Water wants to put the other two on hold and instead see whether rain gardens, retention ponds and grass rooftops can soak up as much storm-water runoff as the pipes can store. D.C. Water has asked the Environmental Protection Agency for permission to build an experimental “green infrastructure” project and run tests for at least eight years.
The EPA is considering D.C. Water’s proposed “partnership agreement,” and a decision on whether to move forward with public hearings on the changes is expected soon. The green infrastructure proposal is an attempt to delay or cancel part of the tunnel. (Wash Post, 12/3/2012)
