These planning Guidelines, including the analysis of the benefits and costs of conservation activities, emphasize a water supplier perspective. The value of conservation is defined primarily in terms of avoided supply-side costs to the water system. Lowering the level of water demand can help water suppliers avoid, downsize, or postpone the construction and operation of costly supply-side facilities. The benefits of conservation also can be understood from the perspectives of customers, as well as society at large. Conservation benefits society by preserving environmental resources.
