dc.description.abstract A contract was awarded by the International Joint Commission's Great Lakes Regional Office to James F. MacLaren Ltd., to develop, utilizing computer model simulation technology, the relative capital and operating costs to achieve various levels of phosphorus removal at 43 major municipal wastewater treatment facilities in the Lake Erie and Lake Ontario drainage basins. Present sewered populations, wastewater flow and characteristics, and waste and sludge treatment processes in use or planned were used as initial conditions. Treatment facilities were designed and operated, using standard sanitary engineering design parameters, assuming (a) no requirement for phosphorus removal, and (b) phosphorus removal to achieve effluent concentrations of 1.0, 0.5, 0.3 and 0.1 mg/L as "P". A computer model was used to simulate wastewater treatment facilities, including sludge treatment and disposal, for each of the 43 municipalities, under various phosphorus final effluent requirements. Capital costs required to build the facilities in 1975, expand them as necessary over a 25 year period were simulated (1). Some of the more significant engineering assumptions related to phosphorus removal technology used in the simulation model are discussed in Appendix B. The total phosphorus loads which would be discharged to the Great Lakes System under each assumed scenario were also determined. The results for the plants in the Lake Erie and Lake Ontario Basins are summarized in Tables A2 and A3 respectively in Appendix A. These results were then used to determine per capita costs for use in the PLUARG Overview modelling activities to estimate costs for point source reductions in phosphorus loads to the Great Lakes to compare with costs to reduce inputs from land runoff.
