In the context of an OSSF, what does “effluent” refer to?

In the context of an On-Site Sewage Facility (OSSF), the term "effluent" specifically refers to treated wastewater that is released from the septic tank or treatment system. This treated effluent has undergone a process to reduce harmful pathogens and pollutants, making it suitable for further treatment or discharge into the soil or a designated area, typically through a drain field.

Understanding this definition is crucial because it differentiates effluent from untreated wastewater, which contains contaminants that have not been processed and can pose health risks. The effluent must meet specific treatment standards before it can be safely returned to the environment or utilized for irrigation. This definition is essential in managing and maintaining effective sewage systems while protecting public health and the environment.
