The three principal roles of wastewater reclamation are: (1) Provides an additional water supply; (2) serves as an economical method of treating and disposing of wastewater; and (3) enhances the environment. By comparing the future water demands and supplies for Southern California, a water deficiency is predicted. Sanitation agencies have discovered it is often less expensive to reclaim and deliver waste water for reuse than construct additional trunk sewers, treatment plants, and ocean outfalls. Reclamation and reuse of wastewater reduces the adverse impact on the receiving waters caused by discharge of untreated or partially treated liquid wastes. In water-deficient areas, the aesthetics of an area can be improved by use of reclaimed water for the irrigation of new parks, greenbelts, golf courses, and freeway landscaping.
