A new type of septic technology allows homes to be built on some lots that were previously considered unbuildable. The system consists of a stainless-steel treatment unit placed on top of a two-chamber septic tank.
Effluent from the septic tank is pumped through the unit rather than flowing to a leaching field. Biomedia remove nitrogen, phosphorus, viruses, bacteria, and other organic contaminants. The unit’s output is clean enough to be discharged into the environment or for use in landscape watering. The installed cost for the system is about twice that of a conventional septic system.
