Bioretention

This article is about planted installations designed to capture surface runoff through an engineered soil with subterranean infrastructure.
For simpler, residential systems, see Rain Gardens.
For linear systems, which convey flow, but are otherwise similar see Bioswales.

Overview

Bioretention cells are the

Bioretention cells are an ideal technology for:

• People who want bioretention

The fundamental components of a bioretention cell are:

• Biomedia - an engineered soil mix
• Planting -

Additional components may include:
