ABSTRACT
This chapter briefly describes the supply characteristics of treated wastewater with respect to seasonality of flows, transportation costs, and pricing considerations. It examines the components making up economic demand evapotranspiration for treated wastewater, including monthly of adoptable crops, alternative application methods, nutrient value of primary and secondary treated wastewater, and salinity problems. The chapter provides some general comments on risk and uncertainty. It looks at the treatment-disposal system as a whole using a linear programming model of an individual farm to indicate the sensitivity of a profit-maximizing farm operator to variations in the supply-and-demand characteristics and contractual arrangements of reclaimed wastewater. Seasonal variations in wastewater flows occur in communities with seasonal commercial and industrial activities. Landowners/farm operators would have profit maximization as their economic goal, and their decision to purchase or accept treated wastewater will be based on the quantity, timing, quality, and cost of treated wastewater. The choice of whether to use wastewater for irrigation involves risk and uncertainty.
