Green Infrastructure


NACWA has been at the forefront of efforts to advocate for the use of green infrastructure as one way to address the nation’s clean water challenges that result from wet weather. Green infrastructure includes vegetated swales, rain gardens, porous concrete, and rain barrels to capture or divert storm water that otherwise would go directly into the sewer system and uses nature’s own mechanisms for treatment.
