Why Aerobic?

Conventional septic systems provide adequate treatment under many conditions; however, because they discharge contaminated wastewater into the natural environment they depend on natural processes to complete the waste treatment. They require a substantial thickness of free draining soil, and groundwater must be located well below the disposal lines. If these conditions are not met then septic soil conditions and/or groundwater contamination can result.

Before Digging Up Your Yard...

If your septic system is fouled by biological clogging (biomat), we can rehabilitate it without destroying existing landscape and at a fraction of the cost of system replacement.
