This article is about planted installations designed to capture and convey surface runoff through an engineered soil with subterranean infrastructure.
For node type systems, see Bioretention Cells.

Overview[edit]

Bioswales are linear landscape features consisting of a drainage channel with gently sloping sides. Underground they are filled with engineered soil and a water storage layer of coarse gravel material.
They are sometimes referred to as 'dry swales', 'vegetated swales', 'water quality swales' or 'inline bioretention'.

Bioswales are an ideal technology for:

  • Sites with long linear landscaped areas, such as parking lots
  • Connecting with one or more other types of LID

The fundamental components of a bioretention cell are:

  • Biomedia - an engineered soil mix
  • Planting
  • Underdrain with clean out and inspection ports

Additional components may include:

  • Impermeable membrane to prevent infiltration to soils below
  • Check dams
