Wastewater treatment system

Claim 2

A wastewater treatment system having a septic tank and a filter bed downstream from the septic tank for collecting effluent being discharged from said septic tank, filtering the effluent, and discharging effluent directly into the underlying environment, said filter bed comprising: (a) at least one modular housing member, said modular housing member comprising a generally elongated tubular member having at least one open end and a collecting chamber for collecting filtered effluent and discharging at least a portion of said effluent into the environment underlying said modular housing member; (b) at least one reattachable end panel having recesses corresponding in shape to the at least one open end of said modular housing member; and (c) at least one filter medium in said modular housing member.

Claim 3

A wastewater treatment system having a septic tank and a filter bed downstream from the septic tank for collecting effluent being discharged from said septic tank, filtering the effluent and discharging the effluent directly into the underlying environment, said filter bed comprising: (a) at least one modular housing member comprising a generally elongated tubular member having at least one open end and a collecting chamber for collecting filtered effluent and discharging at least a portion of said effluent into the environment underlying said modular housing member; (b) at least one reattachable end panel having recesses corresponding in shape to the at least one open end of said modular housing member, the at least one said end panel having opposing first and second recesses for adjoining a first and a second modular housing member, said first recesses corresponding in shape to the at least one open end of said first modular housing member and said second recesses corresponding in shape to the at least one open end of said second modular housing member; and (c) at least one filter medium in said modular housing member.

Claim 4

A wastewater treatment system having a septic tank and a filter bed downstream from the septic tank for collecting effluent being discharged from said septic tank, filtering the effluent and discharging the effluent directly into the underlying environment, said filter bed comprising: (a) at least one modular housing member comprising a generally elongated tubular member having at least one open end and a collecting chamber for collecting filtered effluent and discharging at least a portion of said effluent into the environment underlying said modular housing member; (b) at least one reattachable end panel having recesses corresponding in shape to the at least one open end of said modular housing member, the at least one said end panel having opposing first and second recesses for adjoining a first and a second modular housing member, said first recesses corresponding in shape to the at least one open end of said first modular housing member and said second recesses corresponding in shape to the at least one open end of said second modular housing member; and (c) at least one filter medium in said modular housing member.

Claim 5

A wastewater treatment system having a septic tank and a filter bed containing filter media downstream from the septic tank for collecting effluent being discharged from said septic tank, filtering the effluent and discharging the effluent from said filter bed, said filter bed comprising: (a) a generally elongated collecting chamber having at least one open end, said collecting chamber having a means for distributing the effluent being discharged from the filter media into said collecting chamber and a means for discharging at least a portion of said effluent into the environment underlying said collecting chamber; and (b) at least one reattachable end panel having recesses corresponding in shape to the at least one open end of said collecting chamber.

Claim 6

A wastewater treatment system having a septic tank and a filter bed containing filter media downstream from the septic tank for collecting effluent being discharged from said septic tank, filtering the effluent and discharging the effluent from said filter bed, said filter bed comprising: (a) a generally elongated collecting chamber having at least one open end, said collecting chamber having a means for distributing the effluent being discharged from the filter media into said collecting chamber and a means for discharging at least a portion of said effluent into the environment underlying said collecting chamber; and (b) at least one reattachable end panel having recesses corresponding in shape to the at least one open end of said collecting chamber.

Claim 7

A wastewater treatment system as recited in claim 3 wherein said collecting chamber of said filter bed has an upper surface and a lower surface, and said distributing means comprises a plurality of distribution orifices located on the upper surface of said collecting chamber.

Claim 8

A wastewater treatment system as recited in claim 3, wherein said collecting chamber of said filter bed has an upper surface and a lower surface and said discharging means is a plurality of discharge orifices located on the lower surface of said collecting chamber.

Claim 9

A wastewater treatment system as recited in claim 3, wherein the at least one said end panel of said filter bed has first and second opposing recesses for adjoining a first and a second collecting chamber, said first recesses corresponding in shape to the at least one open end of said first collecting chamber and said second recesses corresponding in shape to the at least one open end of said second collecting chamber.

Claim 10

A wastewater treatment system as recited in claim 3, wherein said collecting chamber of said filter bed comprises at least one return channel and at least one discharge chamber.
