Abstract
An apparatus and method for treatment of waste water effluent includes a main conduit connected to a source of waste water, and a removable filter positioned within the main conduit, the filter comprising a light weight particulate material for filtration of the effluent. A drain field for filtration treatment of waste water effluent comprises a source of waste water effluent, a main conduit in fluid connection with the source of waste water, and at least one in-line filter positioned within the main conduit, the filter comprising light weight particulate material. The drain field may comprise at least one extension conduit connected in fluid communication with the main conduit and extending substantially upwardly therefrom, said extension conduit having a removable cap comprising a sensor to thereby generate a signal when water in said extension conduit reaches a predetermined level.
