Stormwater Management – Outflow Treatment (Baffle Boxes)
Baffle boxes are infrastructure components typically found near the end of the stormwater management system, positioned at outfalls or in types of stormwater management infrastructure. Baffle boxes attach to stormwater outfalls and contain a series of sediment settling chambers separated by baffles. Stormwater runoff enters through the boxes which capture sediment and pollutants in the storage zones. When the first chamber is full, flow is directed to the second chamber, and so on. Larger particles, including marine debris, tend to settle in the first chamber and smaller particles associated with sediment accumulate in the other chambers.
