EPA proposes rainwater-trapping rules for D.C.

“The U.S. Environmental Protection Agency announced plans Wednesday to require “green roofs,” rain barrels and other measures that trap runoff at new and redeveloped buildings in the District, making the city a test case for an ambitious effort to stop pollution from flowing into rivers along with the rain.

“The EPA’s plan, contained in a proposed permit for the District’s storm-sewer system, would require developers to trap 90 percent of the water that falls on a plot during a storm.”

“In the EPA’s plan, “you’re using water on site as an asset, rather than a waste product,” said Jon Capacasa, director of the water protection division of the EPA’s mid-Atlantic regional office. He said the changes were part of a larger effort, begun with a presidential order last year, to improve the Chesapeake Bay and its tributaries. “The local water bodies need these levels of [storm water] control to be healthy,” he said.”

“With more people moving into the Portland area, and agriculture a major industry in the Willamette Valley, the amount of available ground water is diminishing.”

Not Just a Drop in the Bucket

“A new report released last fall by consulting firm McKinsey & Company declares that by 2030, the world’s water demands will have increased by 40%. Add to that the fact of rising seas, droughts, and shrinking water sheds, and cities across the country are starting to respond with some particularly innovative solutions tailor-made to their varied water needs.”
