Aerobic Treatment Units (ATU)

WHAT IS AN AEROBIC TREATMENT UNIT?

Many new and existing homes these days are opting to install aerobic treatment units (ATU), rather than conventional septic systems.

Aerobic Treatment Units are similar to standard septic systems in that they use natural processes to treat wastewater. But unlike conventional systems, ATUs also use oxygen to break down organic matter, much the same as municipal wastewater treatment systems, but in a scaled-down version.

Because ATUs decompose organic solids quickly, the wastewater leaving the system is cleaner. ATUs are useful in environmentally sensitive areas or locations that are less suitable for conventional or gravity flow septic systems, such as inappropriate soil conditions where the water table is too high to allow the leach drains to operate effectively.
