A mathematical model has been developed for the preliminary screening of wastewater management alternatives involving treatment and discharge to receiving waters and land application. The model consists of a dissolved oxygen model of receiving waters, mass balances of nitrogen and water at the land application site and cost estimating equations. The model is used to estimate costs and water quality impacts on surface and ground waters of wastewater management options. The objective of the model is the identification of alternatives that demonstrate cost-effective potential as specified in regulations for best practicable waste treatment technology (BPWTT). The screening model was used to evaluate wastewater management alternatives for a hypothetical city with a wastewater flow of 10 mgd.
