Site & Soil Evaluation (Soil Test)

   One of the first things that need to be done before purchasing any vacant piece of property is to have a site & soil evaluation (soil test). This soil evaluation is commonly (although mistakenly) called a "perc test". Perc tests used to be the common method for determining the design of "POWTS", (Private Onsite Wastewater Treatment Systems) was the method where water was literally poured into holes in the ground for the purpose of measuring just how far into the ground a certain amount of water would go in a certain amount of time, thus determining the soils percolation rate. The perc method is no longer the accepted method in Wisconsin of "soil testing", as the information gathered is far too limited for making accurate determinations of important soil characteristics.

   A soil evaluation is a method used to determine if the site and soil conditions can absorb wastewater from a private sewage (septic) system. Wastewater is all water that carries waste derived from ordinary living such as toilets, sinks, dishwashers, laundry, etc. If the site does not have suitable soils, it will not be suitable for an on site waste disposal system.

   A soil evaluation is a prerequisite in obtaining a Sanitary permit for the installation of a private sewage system. It's also a key in evaluating your property and determining where you would like to place your new home or commercial building. It's not difficult to have done and in the long run will save you time and money while giving you piece of mind.

   The Site & Soil Evaluation is conducted by a certified soil tester (CST). Wisconsin law requires that a licensed Certified Soil Tester perform soil evaluations. The soil tester performs the required tests and provides the property owner and the Zoning department with a copy of the results. The soil tester will inform the owner if the tests are suitable or unsuitable.

   A Soil Evaluation must be completed or on file at the local County Zoning Office to obtain a sanitary permit for a septic system before a building permit can be issued.

   Once a Soil Evaluations is completed, a soil sheet will be filled out, along with a drawing/plan to scale for the private waste disposal system, which is designated by the soil tester, and given to the owner. No structures should be placed within this area or located within 25 feet of the designated area. That area must be set aside and used for the effluent treatment. Therefore, it is important that you inform the soil tester where you desire to place your structure.
