What characterizes an advanced treatment system (ATS)?

An advanced treatment system (ATS) is characterized by its capability to enhance the quality of septic effluent beyond what is achieved by conventional septic systems. This is achieved through the use of specialized technology or processes that treat wastewater more effectively, reducing pollutants before the effluent is released into the environment. An ATS may utilize filtration, disinfection, or bio-treatment methods that are specifically designed to meet higher standards for water quality.

The designation of ATS encompasses a range of approved treatment devices that are engineered to address specific environmental concerns or regulatory requirements, such as nutrient removal or pathogen reduction. This makes these systems particularly valuable in areas where soil conditions are poor for traditional septic systems or where public health and environmental protection are of paramount concern.

The other options do not accurately represent the definition or purpose of an ATS. A conventional septic tank does not provide advanced treatment; it primarily separates solids and allows for basic microbial breakdown. A standard sewer line installation refers to the infrastructure for carrying wastewater away to a treatment facility, not an in-situ treatment process. Treating solid waste directly does not align with the function of an ATS, which focuses on wastewater treatment rather than solid waste management.
