Smart drain is a polymer ribbon-like material with capillary drains on the underside. It's use has been demonstrated in bioretention. <ref>Redahegn Sileshi; Robert Pitt, P.E., M.ASCE; and Shirley Clark, P.E., M.ASCE Performance Evaluation of an Alternative Underdrain Material for Stormwater Biofiltration Systems, Journal of Sustainable Water in the Built Environment, 4(2), May 2018 https://doi.org/10.1061/JSWBAY.0000845 </ref>. It's low profile may make it particularly well suited to non-infiltrating practices, such as flow-through stormwater planters.
