Buried in your yard and built to last your home septic systems may never have crossed your mind. But out of sight and out of mind it still performs a vital task.
It's a simple concept: a tank, a network of pipes, and billions of microscopic organisms. Yet it's received every flush, every shower, and whatever else you and anyone else who has ever lived in your house has ever poured down the drain. Your septic system treats tonnes of organic waste each season. The tank treats sewage by letting the heavy solid materials settle and allowing time for lighter "scum" to float to the top. This partly treated liquid then flows into perforated pipes, called the leaching bed, where it filters into the ground and is further treated. Helpful bacteria and other soil organisms do the bulk of the work.
