Alternatives For Managing Wastewater In The San Francisco Bay And Sacramento San Joaquin Delta Area PDF Download

This report presents the opportunities and expected accomplishment, both beneficial and detrimental, of regional wastewater management systems to meet the future needs of the Bay-Delta area. Existing water quality problems in the Bay-Delta area will be resolved for the immediate future through the improvements presently planned at local levels. The currently planned additions to wastewater treatment systems offer definite alleviation of present water quality problems but the overall program needed to meet ultimate requirements has yet to be determined. An efficient regional wastewater management system is needed for resolving long-term water quality problems associated with projected excess loadings of pollutants. Each of the alternative wastewater management systems evaluated in this study would result in improved water quality in the estuary. There are definite differences in performance and in environmental protection offered by the alternatives. In addition, each could be improved in performance by modifications to the basic scheme. The ocean disposal alternative would require extension of outfalls into deep water to avoid adverse effects on the nearshore ecology.
