Aerobic Treatment Unit (ATU) Systems


Frequently Asked Questions

What type of drainfield should be used with an ATU?

It is recommended to speak with the vendor about their recommendation when purchasing the unit. Both drip tubing and conventional drainfield material may work depending on the manufacturer.

Who services the ATU after installation?

Required service by the installer is dependent on the county and their licensure to act as a maintenance entity.

Is an ATU more expensive than a conventional septic system?

Yes, ATUs typically have a higher initial installation cost. They also require electricity to run and have ongoing maintenance costs for servicing, which are not typically associated with standard septic systems.
