Tree Box Filters

Tree box filters consist of a container filled with a soil mixture, a mulch layer, an under-drain system and a shrub or tree. Tree box filters collect rainwater runoff which is filtered by the vegetation and soil before going into the catch basin underneath. Water that is collected in tree boxes helps irrigate the tree.

Tree boxes at the Science Museum

Tree box filters can be a very effective means of controlling runoff, especially when distributed around a site. Tree boxes will be installed in the parking lot around the entrance to the museum.
