  • Sediment Basin Design Fact Sheet

    The size of the settling pond is directly related to the 'volume' of runoff and/or peak design 'discharge'. Pond volume is critical for basins operate as plug flow systems; while the pond surface area is critical for sediment basins that operate as continuous flow systems. Both pond volume and surface area are critical for Type A basins. 4. It should be noted that even if a basin is
