ABSTRACT:
A method for filtering and discharging waste water from a septic tank in predetermined increments and preventing passage of suspended solids from the tank while resisting blockage of the fluid discharge apparatus by such solids. A removable fluid discharge device, such as a submersible pump or dosing siphon with a trigger trap, is enclosed within an encircling filter element which is similarly encircled by a protective housing, and the entire assembly is located within a septic tank immersed in waste water. The protective housing is impervious to the passage of waste water into its interior except through apertures located in the vertical sidewalls so situated as to allow water from only the clearest layer within the tank to enter into the housing and contact the filter. Functionally, the housing protects the filter from blockage by the high concentration of solids present in the layers above and below the clearest layer. The encircling filter has a much larger surface area than the discharge pipe so that sufficient filtered waste water is available for discharge even when the filter becomes substantially blocked.
