ABSTRACT:
A waste water treatment facility includes a gravity flow treatment bed which receives waste effluent from a plurality of individual septic tanks. The treatment bed includes a bottom layer of small gravel particles, a layer of larger gravel particles covering the bottom layer, a strip of crushed limestone, a layer of straw or hay on the large gravel layer, and a layer of topsoil in which reeds are planted for treating the effluent. A perforated header pipe distributes the incoming effluent across the bed, and a perforated collection pipe collects the treated effluent and delivers it to a sump. The effluent passes from the sump through a chlorinator and a chlorine contact chamber before being discharged to the ground.
