Infiltrator ATL

Infiltrator ATL (Advanced Treatment Leachfield)

ATL by Infiltrator is passive advanced treatment leachfield system designed as an environmentally friendly alternative to traditional stone and pipe drainfields. The ATL system is a sand-lined treatment and dispersal leachfield system

 

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:

  • Produces Class 1 (EPA secondary) treated effluent
  • 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
