• Aerobic Treatment Tanks (ATU)
    • An alternative to the septic tank is an aerobic treatment tank.
    • These systems utilize an air compressor or a churning propeller (aerator) to maintain an aerobic environment for the growth of aerobic microorganisms.
    • These microorganisms break down the sewage like the anaerobic bacteria found in the septic tank.
    • Proper functioning of this type of treatment tank is highly dependant upon the diligent maintenance of the mechanical components of the aerobic system.
  • ATU Maintenance

    • The mechanical portion of the aerobic tank requires routine maintenance and supervised operation.
    • The aerobic tank must be pumped out as needed to remove the accumulated solids.
    • All mechanical parts, electrical controls and alarms must be checked periodically by a technician who is familiar with the proper installation of these parts.
    • A technician must periodically check to see that the motor for the aeration device is running properly and aerating the wastewater. If it is not, instead of an aerobic environment for the breakdown of sewage, an anaerobic environment will be created.
