Unit 5  |  Toward Sustainable Water Systems 131 Green building also encompasses strategies that prevent excessive runoff and the transport of pollutants into water bodies. There is great potential to redesign city infrastructure in order to make water use and water systems much more sustainable. Many buildings and municipalities are replac- ing standard asphalt or concrete pavement with permeable pavement . Normally, rainwater that falls on roads, sidewalks, or parking lots quickly runs off into storm drains, putting a strain on sewer systems and carrying pollutants such as motor oil and road salt into water bodies.
