Conserving Water Resources With Green Infrastructure
By Trey Cody
EPA employees in Fort Meade, Maryland at the Environmental Science Center recently added some unique environmental features to their building, which is home to Region III’s chemistry and microbiology labs. EPA staff helped construct a rain garden with native grasses, goldenrod, coneflowers, and http://www.epa.gov/greeningepa/glossary.htm rerouting rooftop drainage pipes to a rain barrel to help reduce splash erosion as stormwater falls from roof gutters to the garden. The rain garden makes for a beautiful sight for workers at the front of the building and is watered both naturally and with the rain barrel.
These improvements and more are helping this facility in its effort to meet the Guiding Principles for Federal Leadership in High Performance and Sustainable Buildings as well as working towards achieving a U.S Green Building Council, Leadership in Energy and Environmental Design existing building certification.
This is just one way that EPA is helping to improve water quality by the construction of green infrastructure in our region. There are numerous other examples of how new products, technologies, and practices can use natural systems to enhance water quality. Some of these can be implemented in your local household or business. The great thing about green infrastructure is that while it is improving water quality, you can save water, money and energy.
Below are some examples of green infrastructure that you can implement to your house to promote water quality. You can click each one to view more information, fact sheets, benefits, examples and web sites.
- Downspout Disconnection: The rerouting of rooftop drainage pipes to drain rainwater to rain barrels, cisterns, or permeable areas instead of the storm sewer. Home owners can disconnect and reroute these pipes with little to no effort!
- Rain Gardens: Shallow, vegetated basins that allows for the collection and absorption of runoff from rooftops, sidewalks, and streets. Rain gardens mimic natural hydrology by infiltration, evaporation, and returning water vapor to the atmosphere. They can be installed in almost any unpaved space. This is a great way for a homeowner to beautify their homes and improve water quality!
- Permeable Pavements: Paved surfaces that allow infiltration, treating, and storage of rainwater where it falls. Permeable pavements may be constructed from pervious concrete, porous asphalt, and several other materials.
Have you installed any of these or other examples of green infrastructure in your household?

2012 marks the 40th anniversary of the Clean Water Act, the nation’s law for protecting our most irreplaceable resource. Throughout the year, EPA will be highlighting different aspects of the history and successes of the Clean Water Act in reducing pollution in the past 40 years. The month of August will focus on Science and Innovation.
