Aerobic Treatment Units
These types of treatment units are very common throughout Central Texas, that is because these systems inject oxygen into the treatment tank to stimulate the growth of natural bacteria and accelerate treatment. ATU’s can be used where soil conditions do not allow for more conventional systems, or where groundwater is present.
This tank is meant to work alongside a drip system, surface application, and to some extent, a low pressure dose system. A maintenance contract is required for this system.
Drip Distribution:
A drip system is an advantage if you have inadequate soil or have a small lot. This system is still dependent on the soil; however, it is more versatile. This system is to work alongside an ATU. A maintenance contract is required for this system.
Surface Application:
Most commonly known as “sprinkler system”. The system is to work alongside an ATU, unlike a drip system, the surface application system often needs space to fit the applicable area for treatment. These are usually the biggest footprint that a system requires, and therefore less common if you do not want to relocate large amounts of your land to the system. The ATU will require constant use of chlorine as well as maintenance.
Aerobic LPD System:
The aerobic LPD system, although less common, this system works alongside an ATU to provide further treatment of the effluent that goes to the drain field. The drain field is usually made up of chambers or pipe and gravel.
