- ATU stands for Aerobic Treatment Unit
- ATU must be inspected on a yearly basis.
- ATU are typically found in smaller lots with larger homes.
LandPerc performs ATU with Dripline upon request. An ATU is similar to septic systems in that they both use natural processes to treat wastewater. But unlike septic (anaerobic) treatment, the aerobic treatment process requires oxygen. Aerobic treatment units (ATUs), therefore, use a mechanism to inject and circulate air inside the treatment tank.
