(1) motion of the water through the system. Evaluation of each gross pollutant trap design involves testing different flow rates with different pollutant loadings to determine the design's potential. A secondary 750mm pipe will carry the filtered The following observations have been used as criteria in which to judge the effectiveness and efficiency of each design (beecham and sablatnig, 1994):
