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:
- Underdrain with clean out and inspection ports
- Impermeable membrane to prevent infiltration to soils below
- Check dams to facilitate short tern ponding
