This article is about installations designed to capture and convey surface runoff along a vegetated channel, whilst also promoting infiltration.
For underground conveyance which promotes infiltration, see Exfiltration trenches.
For design recommendations on grassed channels, see Enhanced grass swales.

Overview[edit]

The fundamental components of a bioswale are:

  • A graded channel
  • Planting
  • Filter media, to permit infiltration into the facility (not necessarily to soils below)

Additional components may include:

Planning considerations[edit]

Design[edit]

Bioswales are sized as narrow linear bioretention cells. Drawdown times of bioswales are typically lower than other geometric configurations of bioretention facilities.
