Bioretention Planter

Bioretention (also referred to as flow-through) planters act as an on-structure organic filter for stormwater systems.
Tournesol Siteworks offers several standard configurations as well as custom designs to meet your specific application. The Bioretention planters are available in lightweight GFRC and feature an internal waterproof sealant and 4” diameter drainage plumbing. Bioretention media is typically specified by local authorities or to code.

How does bioretention work?

Stormwater is collected and enters from a drain lead. As the water enters the planter, the vegetation, gravel and bioretention media filters pollution and heavy metals. The sealed planter allows temporary ponding of stormwater runoff before the water passes through to the drain into the stormwater system.
