rainwater conservation and reuse

Urban areas are losing green space at an accelerating rate.  As population grows and migrates to cities, more land is developed for buildings and infrastructure.  Much of this construction consists of impermeable surfaces – streets, parking lots and rooftops.  An increasing amount of the rainfall is flowing off of these surfaces and into storm drains that exit into waterways.

Rainwater washes over 70,000 tons of trash and toxic pollution directly into District waterways every year.  By capturing rainwater in green roofs, rain gardens and rain barrels, the volume of pollutants, toxins, and trash entering the Anacostia and Potomac Rivers, and Rock Creek is lessened.  The greater the collection and abatement of rainwater on site, the goal of restoring our rivers and streams to better health for aquatic life and recreational uses is approachable.
