Calculation Spreadsheet: TSS Removal

Excel spreadsheet may be used to calculate the required Total Suspended Solids removal.

Using our spreadsheet may decrease the time it takes the agency to review your project. The April 20, 2009, version of the calculation spreadsheet includes a clarification to the sizing for AquaLogic, a correction to the grassy swale flow velocity, a way to oversize Stormceptor and Vortech, and the addition of drop down menus. Include a separate spreadsheet for each drainage basin.
