Septic system screened pump vault

Abstract

A septic system filtered pump vault comprises a housing for an effluent pump, a plurality of effluent filters contained within a filter compartment that is located in the housing, a filter support within the housing. The filters are secured to the filter support in spaced relation to one another so as to provide filtering sections between the filters. The filter support includes at least one backflush conduit provided with a plurality of backflush orifices oriented to direct backflush fluid into the filtering sections onto upper surfaces of the filters. An effluent pump is contained within the housing for effecting flow of effluent through the effluent inlet and through the filters. The pump includes a discharge conduit for discharging filtered effluent from the housing. Valving communicates with the backflush conduit and the discharge conduit so that the pump may be selectively communicated with the backflush conduit to effect backflushing of the filters with filtered effluent. The filter support includes an air conduit having an air discharge manifold, the air discharge manifold having air discharge orifices oriented to direct air into the filter compartment, and the valving communicates with the air conduit so that air from an external source may be selectively directed into the air discharge conduit for selectively aerating effluent contained with the filter compartment.
