The septic tank and drain field is the most common form of on-site waste water treatment for homes not hooked up to sewer lines. It involves the use of a large underground tank where solids settle and are partially broken down, followed by a drain field where the remaining liquid is dispersed into the soil for further treatment. The other options listed (active composting, chemical "flush," electrical induction sterilization, and soil enrichment) are not commonly used or effective for residential wastewater treatment.
