Instructions for Using Worksheets

The included files will only work if you have Microsoft Excel installed on your computer. They were created using Excel 2000. 

You can get more information on using Microsoft Excel at http://www.microsoft.com/office/excel/. You can also purchase the software from the Microsoft web site or you can purchase the software at any computer store. 

For all worksheets, you need to enter some information. The required input information is the boxed ( ) section of the worksheets.

If you have problems or suggestions about the worksheets, please call Sara Christopherson at (612) 625-7243.

As the work sheets are regularly updated, you can download them for free from our Web site at http://septic.umn.edu.
