Issues of Concern Related to Underground Infiltration Systems for Stormwater Management & Treatment

This Transportation Research Synthesis (TRS) provides an overview of relevant literature, regulations, guidance, and other information related to a specific stormwater Best Management Practice (BMP), underground infiltration systems with sump manhole pretreatment. This TRS is intended to serve as part of the justification to prompt a review of this practice and related practices in the context of a revision to the Minnesota Stormwater Manual (MSWM).
