Abstract
A study to determine the relative efficiencies of six catch basin inlet grates has been conducted by the Division of Research, Ontario Water Resources Commission. The evaluation was carried out in the OWRC laboratory on a wooden gutter, using river water. No attempt was made to duplicate field conditions and thus it was the relative efficiencies rather than the actual field efficiencies which were determined. The catch basin inlet grates studied were found to be in the following decreasing order of efficiency: Rowland grate, Michigan grate, New York grate, DHO-SD-7-74 modified grate, DHO-SD-7-74 standard grate and DHO-DD-706 grate.
