There are certain situations when a conventional On-site Sewage Facility cannot be installed. In the case of rock, ground water or clay soil, the water from the septic system cannot be absorbed quickly enough or not at all. In these circumstances, an aerobic system is one of the options available to the property owner.
An aerobic system consists of a tank, a pump, a chlorinator, an air compressor, and a sprinkler system. The efflluent from the house passes through 3 chambers in the tank where it is cleaned. This water is then chlorinated in the third tank and pumped to sprinklers for surface irrigation. In addition to an On-site Sewage Facility, you also have a sprinkler system.
