Natural Resources Research Institute Technical Report

Abstract

Final Report Submitted to: Minnesota Technology, Inc., Legislative Commission for Minnesota Resources, Electric Power Research Institute; Funding Period July 1995 through June 1997The major objectives at the northern site were 1) to design, construct, monitor and compare the yearround performance of alternative treatment systems, with respect to a conventional trench system, for treatment of typical single family wastewater flows (based on the removal of fecal coliform bacteria, BOD5, TSS, phosphorus, and nitrogen); 2) to compare subsurface water quality at several depths below drainfield trenches receiving discharge water from a conventional (i.e., septic tank) and alternative systems; 3) to design, construct, and monitor the performance of a subsurface drip irrigation system at different depths in the s0il; 4) to design, construct, and monitor the performance of a pressurized sewage treatment system utilizing small diameter pipe and a subsurface flow, constructed wetland treatment system for a .cluster of lakeshore homes on Grand Lake in order to demonstrate that this alternative technology could correct a problem representative of numerous other situations in Minnesota; and 5) to develop a technology transfer plan for effectively communicating the results of this study to the private sector, the public (i.e., potential users), and the appropriate local and state agencies.University of Minnesota Duluth, Natural Resources Research Institute, 5013 Miller Trunk Highway, Duluth, MN 55811-1442; St. Louis County Health Department, Duluth, MN 55802; Western Lake Superior Sanitary District, Duluth, MN 55806-1894; Department of Biosystems and Agricultural Engineering, University of Minnesota, St. Paul, MN 55108; Wetland Management Services, Chelsea, MI 48118-9527; Ayres and Associates, Madison, WI 53704; Minnesota Pollution Control Agency, St. Paul, MN 55155McCarthy, Barbara J; Axler, Richard P; Monson Geerts, Stephen D; Henneck, Jerald; Crosby, Jeff; Nordman, Del; Weidman, Peter; Hagen, Timothy S; Anderson, James; Gustafson, David; Kadlec, Robert; Otis, Richard; Sabel, Gretchen.
