A rapid increase in population accompanied by sustained improvement in living standards has necessitated the consideration of expanding the water treatment and or distribution systems in many areas. To aid in these considerations an economic decision model for selecting optimal expansion plans has been developed. The model formulated is composed of an objective function minimizing the total cost of investment and operation and set of constraints on the treatment and storage capabilities satisfying the annual requirements on the expected maximum daily demand. Equalization during the daily peak period and fire fighting scale effects in the capital and operating costs were represented in the model by exponential functions. Demand was assumed to continuously increase over a finite period beyond which it stays at a maximum level. The original nonlinear formulation was linearized and then applied to the Champaign-Urbana area for demonstration purposes. (Author)
