Level spreader
A level spreader is an erosion control device designed to reduce water pollution by mitigating the impact of high-velocity stormwater surface runoff. It is used both on construction sites and for permanent applications such as drainage for roads and highways. The device reduces the energy level in high-velocity flow by converting it into sheet flow, and disperses the discharged water so that it may be infiltrated into soil. [1] [2]
Level spreaders may be used in conjunction with runoff infiltration devices such as bioretention systems, infiltration basins and percolation trenches.
