Research output: Book/ReportOther report

Abstract

Projections of the volume of sewage flow into the Metropolitan Wastewater Treatment Plant (Pig's Eye plant) serving the Minneapolis-St. Paul metropolitan area have compelled the Metropolitan Sewer Board to plan an expansion of the existing treatment facilities at Pig's Eye Island on the Mississippi River. A listing of selected anticipated flows is given in Table A-l of Appendix A. Under the title "Project 71" it is planned to increase the pretreatment and primary treatment capacity from an existing 260 MGD design capacity to 620 MGD, which corresponds to the present interceptor capacity. The increment of 360 MGD will be treated in new and separate facilities to be located to the east of the existing ones. To route part of the flow to the new facilities, a diversion (division) structure in the main interceptor just north of the existing plant is projected.
