The MaxWell® Plus Drainage System is a dual-chambered infiltration BMP that pre-treats stormwater twice for constituent removal prior to infiltration. The MaxWell Plus offers field-proven efficiency, and has become the standard of quality utilized by numerous municipalities in California and Arizona and the overwhelming choice of specifying civil engineers in the private sector. This popular model is best used in large paved areas when connected with underground storage tanks or where there is an abundance of silt, sediment and debris runoff.
During the pre-treatment process, this design traps out suspended solids and debris, and wicks away petroleum-based organic compounds from the inflow. Both chambers are equipped with hydrocarbon capture pillows filled with unique polymer beads, which capture a wide range of hydrocarbons and liquid organic compounds.
