Full Service Septic System Designs from S&H Land Services Includes:

Test Pits: A test pit is performed by digging a hole with an excavator, approximately six or seven feet deep, in the area of the proposed septic system. A licensed septic system designer then logs the soil morphology and determines the seasonal high water table.

Percolation Test: Often referred to as the "perc-test", measures the rate water moves through the soil on your property. This is one of the components used to size the leach bed area.
