Revision as of 21:14, 26 May 2015

Best Management Practices that infiltrate stormwater runoff into underlying soil include, but are not limited, to

  • infiltration basins,
  • infiltration trenches,
  • underground infiltration,
  • bioinfiltration,
  • permeable pavements, and
  • tree trenches and tree boxes.

These are discussed briefly below.

Infiltration basin

1 Due to a size restriction; 2 Unless the infiltration practice is located in an industrial area with exposed significant materials or from vehicle fuelling and maintenance areas. Infiltration BMPs are PROHIBITED in these areas; 3Underground infiltration systems will have different pollutant removal capabilities than what is provided in this table. These systems may have a wider application range, however, there is concern that they do not provide adequate treatment of the pollutants; 4 This is only for the portion of flow that enters the infiltration basin; by-passed runoff does not receive treatment; 5 Low = < 30%; Medium = 30-65%; High = 65 -100%); 6 Assumes adequate pre-treatment

An infiltration basin is a natural or constructed impoundment that captures, temporarily stores, and infiltrates a design volume of water. For more information, see the following pages in this Manual.

An infiltration trench is a shallow excavated trench that is backfilled with a coarse stone aggregate allowing for the temporary storage of runoff in the void space of the material in addition to the storage above the aggregate within the trench. For more information, see the following pages in this Manual.

Infiltration BMPs are PROHIBITED in these areas; 2 This is only for the portion of flow that enters the infiltration basin; by-passed runoff does not receive treatment; 3 Low = < 30%; Medium = 30-65%; High = 65 -100%); 4 Assumes adequate pre-treatment; 5 This assumes no raised underdrain; 6 Certain soil mixes can actually leach P.

Bioinfiltration basins, often called rain gardens, use soil (typically engineered media or mixed soil) and native vegetation to capture runoff and remove pollutants. Both the media and underlying soil typically have high infiltration rates that allow captured water to infiltrate within a required drawdown time, usually 48 hours. For more information, see the following pages in this Manual.

Permeable pavements allow stormwater runoff to pass through surface voids into an underlying stone reservoir/ subbase for temporary storage and/or infiltration. They are suitable for driveways, trails, parking lots, and roadways with lighter traffic. For more information, see the following pages in this Manual.

Tree trenches and tree boxes (collectively called tree BMPs), consist of trees planted within underground storage reservoirs designed to retain a volume of runoff for the purpose of uptake by trees. They are a variant of bioretention BMPs. For more information, see the following pages in this Manual.
