The Stormwater Blog From Contech Engineered Solutions

The terms "high-rate biofiltration" and "runoff reduction" aren't often used in the same sentence. The engineering community has a preconceived notion that a high-rate biofilter with an underdrain (like Filterra®) can't provide runoff reduction benefits because the stormwater it treats moves through the practice too quickly.
