Sizing

The STORMTREAT SYSTEM is sized based upon the water quality design storm, the area of impervious surface, the amount of water processed during the storm and the available storage volume of preliminary detention. Generally, 1 to 2 units per acre of impervious surface are required to meet standards. In order to calculate the number of units and detention best suited for your application, download the StormTreat Sizing Worksheet (STSSizingWorksheet.xls) file below.
