In the most basic terms, a typical septic system consists of a means of separating the liquid wastes (dispersed to the outer system) from the solid wastes (held in the septic tank). With proper maintenance, these systems can last 10 – 20 years. We recommend pumping every 3 years. Soil drainage is an important factor in determining the best system for your home. Options include dry wells, leach fields, sand filters, or the newest and best system which is the Jet Aerobic Treatment Unit (Jet ATU). With 50 years of experience, the experts at Thresher Septic Service can answer your questions, provide you with options, and help you make the best decision for your needs.
