May also be referred to as a stormwater pollutant trap (SPT). Types of LSM systems include side entry pit traps, gross pollutant traps, trash racks and litter booms. Living stream: A drainage conveyance system featuring stabilised vegetated banks and a more natural morphology than traditional straight drains, providing diverse habitats for native plants and animals. Loading: The total mass of a contaminant discharged during a storm event. The term may also be used to describe the mass of contaminant intercepted (g/m2) by a device during a storm event, or on an annual basis. (ARMCANZ & ANZECC 2000.) |
