Alternatives for Managing Wastewater in the San Francisco Bay and Sacramento - San Joaquin Delta Area. 9Volume II. Appendix C - Assessment of Impacts of Selected Alternatives.

摘要

In Appendix B the wastewater management alternatives which best represent each of four waste disposal concepts were selected. Appendix C is concerned with assessing the impacts of alternatives for managing wastewater selected in Appendix B. Impact assessment identifies the expected changes in the characteristics of the study area resulting from a wastewater management alternative when compared to the situation assumed to prevail without the alternative. The situation assumed to prevail without the alternative is called the base condition. The base condition for the San Francisco Bay and Delta Area which is discussed in Appendix A represents facilities expected to be constructed or under construction before any of the alternatives developed in this study could be implemented. It assumes complete secondary treatment of municipal wastes at consolidated facilities and pretreatment of industrial wastes. These facilities are expected to have sufficient capacity to handle projected 1990 waste flows. It is then further assumed that these facilities would be expanded to handle 2020 waste flows.
