How It Works

Upon entering the system, septic tank effluent progresses through each component listed below.

  1. 4" diameter pipe
  2. Large-diameter synthetic aggregate
  3. Fine geotextile
  4. Small-diameter synthetic aggregate
  5. Coarse geotextile
  6. 6" thick system sand

Upon exiting the system sand, the treated effluent enters the underlying native soil.

Benefits:

  • Testing in accordance with NSF/ANSI 40 has determined that the ATL system is capable of treating domestic strength wastewater to Class I levels.
  • A passive advanced leachfield treatment – no moving parts or power required
  • Modules are quick and easy to install
  • Shallow system maximizes site suitability and reduces amount of sand fill required
  • No venting and sand cover requirements
