In what situations is an alternative treatment unit (ATU) commonly installed?

ATUs are used when the soils or site conditions won’t adequately treat effluent from a conventional septic system, or when the wastewater is stronger than typical domestic waste. They provide extra treatment before the effluent infiltrates the soil, helping meet required effluent quality and protecting groundwater. This is why they’re commonly installed when site conditions, soil limitations, or high-strength wastewater demand additional treatment before disposal. They’re not meant to replace the septic tank, and they’re not for rainwater; they can apply in residential settings as needed, not only in industrial facilities.
