Infiltrator Chambers Used in Minnesota's First Wetland Cluster Treatment System

The City of Lake Elmo, Minnesota had no sewage collection or central treatment system and had been under pressure by the regional planning agency to allow the regional sewer into the community. Until 1992, regional sewer was not available to Lake Elmo and the entire community was served by onsite wastewater systems. Lake Elmo had purposely restricted its growth through zoning ordinances and land planning activities. The community realized that along with the regional sewer would come high-density development to pay for the high cost of “Big Pipe” infrastructure.
