How Your Septic System Works

In typical on-site treatment systems, all wastewater is co-mingled, treated, and dispersed by one system. There are a few separation systems in which toilet wastes are treated separately from other wastewater.

Common septic systems all have three basic components: plumbing, septic tank, and a soil treatment area. Individual systems may have variations of each of these.
