The document compares the costs of various methods of increasing water and sewer capacity. It provides examples of costs to build new water wells, water treatment plants, sewer plants, and conservation methods. The cost per additional gallon of capacity varies widely between methods, from $7.80 per gallon for high efficiency shower heads to over $50 per gallon for pint urinals or desalination plants. Conservation methods generally have lower per-gallon costs than developing new infrastructure sources. Time frames to implement different options also range from months for conservation to over 5 years for large infrastructure projects.
