Abstract
The 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.
