Abstract:

The present value method of economic evaluation is applied to a water supply problem typical for a military operation. A relevant unit cost figure, called the present value-unit cost PVUC, is determined and applied to alternative methods for meeting a projected need for water. The concepts of reclamation and dual supply systems are introduced and presented as feasible alternatives. A hierarchy of water use is established, with the highest quality intended for potable purposes. A lesser quality is provided for non-potable uses. A mathematical model is formulated and coded in FORTRAN for use on a digital computer. The model incorporates the ideas of a dual supply system by the reclamation of treated wastewaters and the direct reuse of these waters after specified advance treatment. The technique used for economic evaluation is the present-value method, by which a direct comparison between alternatives may be made. The model presented focuses on the relationship of a demand for water and alternative methods to satisfy that requirement.
