Mathematical Modeling for Evaluation of Field Water Supply Alternatives (Arid and Semi-Arid Regions).

A mathematical model has been developed which can be applied to evaluate the least-cost alternatives to meet the projected potable and non-potable water requirements of a US Army Corps-sized operation. It included the adaptation of the model to an existing solution technique, the Out-of-Kilter Algorithm (OKA), a search of the literature to obtain cost data for the various elements within the alternatives, a search of the literature for health and other related factors, a review of existing scenarios, a review of collateral issues pertinent to the production of water in an arid or semi-arid environment, and finally, proposed systems for the re-use of laundry and shower wastewaters.
