Check out the research highlights: Harnessing Water, Waste and Energy Systems for Sustainability:

Many communities are facing challenges of population growth and rising energy costs in the face of diminishing water resources and aging water delivery systems. Although environmental experts have long recognized that Americans must adopt new water and energy conservation methods to ensure a sustainable future, most communities still treat large volumes of water to the highest potable (drinking) water standards and then use much of that treated water for non-potable needs. These include fire fighting, landscape watering, toilet flushing, street cleaning and similar uses. In addition, the quantity and pressure requirements for fire-fighting typically dictate large pipe diameters and storage tanks, causing long standing times with favorable conditions for biological contamination.
