Designer’s Guide CalcTool

The Perc-Rite® drip dispersal Calc-Tool is an easy-to-use Excel spreadsheet that guides you through a Perc-Rite® design. Upon completing the Calc-Tool, you will have everything needed to assemble a complete design package. The Calc-Tool is state-specific and will accommodate all pretreatment processes, including septic tank (anaerobic), aerobic treatment units, media filtration, and any commercially available treatment process.

Instructions: To access your state’s Calc-Tool, hover over your state on the map. Right-click on the Calc-Tool file and ‘Save Target As.’ Open the file from your hard drive. (If you click on the file, it will open in your internet browser. Consequently, any zone detail or PDF link you click on will open in that same browser, erasing everything you have done.) Once the Design Worksheet and Cover Sheet are complete, save it to your hard drive with a job filename at the end (e.g. ‘PercRite Calctool - VA - Job Name.xls’). Click the ‘Submit Calc-Tool File’ button below or send the file as an attachment via email to american@americanonsite.com. We will contact you within 1-2 business days. If your state does not have a Calc-Tool, utilize the NATIONAL CalcTool or contact us and we will develop one for your state.

*Note: The Perc-Rite® CalcTools require an Internet connection to access the zone details and PDF files. These files can also be accessed from the table at the bottom of this page.

2 zone or 4 zone – simplex or duplex

This design eliminates the gravel bed inside the mound resulting in a very low profile installation easy to blend into the existing contour. The effluent discharge volume from each emitter hole is very small. After installation there are virtually no visible indications that the installation site is being used for disposal.
