Media used in rapid bio-filtration devices have hydraulic conductivity rates exceeding 2500 mm/hr. Stormwater360 New Zealand has partnered with Contech USA to produce a rapid filtration media using locally available materials. Current bio-retention guidance limits the hydraulic conductivity of media to less than 350 mm/hr to support plant growth. Using a short-term plant trial (3 months) and 4 long-term ongoing plant trials (11 months+) plant growth was assessed. In total 87 plants were grown (comprising of 28 different tree, shrub and grass species). Out of the plants grown, 81 plants (93%) and 25 plant species (89%) successfully established and grew in rapid filtration media.
