Underground bio retention system for underground water filtration and storage - a "submerged rain garden" supporting large tree growth.
Treebuilders underground bioretention system serves two functions: bioretention and underground water filtration and water storage. The technology is described as a “submerged rain garden”. It exists of soil-containing modular units to support large tree growth combined with on-site stormwater management through absorption, evapotranspiration, interception and filtration. The underground structure avoids taking up extra space in crowded cities. Instead, enough space is provided underground to allow the tree roots to grow, its absence often preventing urban trees from thriving. The modular units simultaneously treat stormwater runoff at source rather than allowing it to enter sewers untreated.
