Use a measurement tape or ruler to find the width (or diameter) in inches of the manhole (or cylindrical tank opening). Next, find the depth (or height) of the unit. Once these measurements are known, add this data to the corresponding calculation fields to properly identify the size of your grease trap (in gallons).
