What is the process for installing a septic system?
(From www.septic-info.com) The following broadly-defined steps delineate how the installation process typically unfolds. Keep in mind that your state and local regulations may differ somewhat! Step 1: Site Evaluation. A professional engineer performs a pit test and a percolation test to determine soil characteristics of your site (which will become design parameters for your septic system). For the pit test, several “observation holes” are dug with a backhoe, to a depth of around seven feet. The engineer observes and records soil layers, color and texture, and notes the depth of groundwater. For the percolation test, water is poured into a “presoaked” hole of 6-12 inches, and the percolation rate (rate at which water level in the hole decreases as water is absorbed) is recorded. The size of the septic system to be built is determined in part by this “perc rate” together with the number of bedrooms in a home, or, for commercial systems, projected estimates of daily water usage.
