The University of Minnesota Onsite Sewage Treatment Program received partial funding from the Minnesota Pollution Control Agency to update its Professional Workshop Manual to coincide with significant Administrative Rule revisions effective 02/04/2008. Our Second Edition incorporated changes to state rule effective 03/14/2011. This following third edition incorporates changes to state rule effective September 2016. This considerable revision could not have been completed without the help of many contributors, namely the manual revision committee. This committee was composed of members of the onsite sewage treatment industry, representing professional organizations, private industry professionals, and government regulators from the local and state level.
This publication was produced by the University of Minnesota Water Resources Center’s Onsite Sewage Treatment Program team in partnership with University of Minnesota Extension. Last updated 01/07/2021
