I am looking at a piece of property to buy. What kind of system will I need?

The type of system you need depends on the type of soil and how much of the soil there is to a water table or other restrictive barrier like ‘hard-pan’ or clay. You will need to meet with a designer to discuss your plans and then dig test holes in the area identified by the designer as meeting setbacks and other necessary features. The designer will evaluate the soils and determine what type of system you will need.


You can also look on the county website at nearby properties to see what type of septic system they have. Keep in mind that some older systems may not meet current code.
