Tightened regulations governing septic systems reflect a growing demand for installation and maintenance of advanced treatment units. In fact, installation of aerobic treatment systems is becoming common practice in new construction sites.Aerobic treatment units are an alternative when challenging sites don’t allow for conventional — anaerobic — septic systems because of site or soil conditions. Both conventional and aerobic systems use natural processes to treat wastewater, but since the aerobic process requires oxygen, these systems include a mechanism to inject and circulate air inside the treatment tank.Increased NSF certifications and these innovative treatment technologies give onsite installers more flexibility in
