Using Graywater and Stormwater to Enhance Local Water Supplies: An Assessment of Risks, Costs, and Benefits is available as a free pdf download. This National Academy of Sciences publication includes the latest thinking on how to tackle the challenges of incorporating graywater and stormwater into water supplies. Communities across the country are looking at graywater from bathroom sinks, showers, bathtubs, clothes washers and laundry sinks as well as stormwater from rainfall or snow as resources to supplement scarce water supplies rather than as waste to be discharged as rapidly as possible.
Stormwater also can recharged groundwater, which may later be tapped for potable use. Harvesting stormwater has many benefits, including saving energy, preventing pollution and reducing the impacts of urban development on urban streams. Reusing graywater can enhance water supply reliability and extend the capacity of existing wastewater systems in growing cities.
Using Graywater and Stormwater to Enhance Local Water Supplies analyzes the risks, costs and benefits on various uses of graywater and stormwater. It examines technical, economic, regulatory and social issues associated with graywater and stormwater capture for uses, including non-potable urban uses, irrigation and groundwater recharge.
