DC Water Proposes Green Infrastructure

The District's water agency is drilling a huge tunnel under sections of the Potomac and Anacostia Rivers through an agreement to end sewer overflow into the rivers. Now DC Water wants to use green infrastructure -- like permeable-pavement bike lanes and rain gardens -- to reduce the need for two more tunnels farther up the Potomac. But some environmentalists are reluctant to give up the tunnels--and their promise of clean rivers--without proof green infrastructure works. Kojo explores the proposal to trade "gray" tunnels for "green" solutions.

Visiting The First Lady Of Clean Rivers

Under the terms of a federally mandated consent decree, DC Water is implementing the $2.6 billion Clean Rivers Project. The first phase of the project is underway and involves constructing a massive underground tunnel system to control combined sewer overflows into the Anacostia River. In this video, DC Water General Manager George Hawkins visits the project's first tunnel boring machine, Lady Bird, on her subterranean job site.
