Upon entering the system, septic tank effluent progresses through each component listed below.
- 4" diameter pipe
- Large-diameter synthetic aggregate
- Fine geotextile
- Small-diameter synthetic aggregate
- Coarse geotextile
- 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
FAQs:
The house (roof) vent functions as the high vent as long as there are no restrictions or other vents between the low vent and the (roof) vent. Please visit the Venting section for more information on recommended vented techniques.
Onsite Wastewater Systems (septic systems) have been installed in cold weather regions for quite some time. If designed and installed properly per code then the systems typically have not froze. Factors such as the temperature of the water exiting the home and proper burial depth of your septic system (septic tank(s) and drainfield) help to ensure adequate system performance. For additional guidance, please contact a licensed septic contractor in your area.
