Abstract
A wastewater treatment and dispersal system wherein wastewater will stand until it has a BOD of less than about 125 mg/l. The dispersal field may comprise inner and outer conduits, an inner conduit and a permeable outer cover, or a trough and an enclosure.
Claims11
A wastewater dispersal system of the type used in conjunction with a septic tank, comprising:
- (a) an inner conduit having a closed bottom and at least one discharge opening at a point spaced above the closed bottom, the inner conduit so configured and the discharge openings so sized and positioned that a volume of wastewater flowing into the inner conduit is retained by and will stand above the bottom of the inner conduit below the level of the discharge openings until it has a BOD of less than about 125 mg/l;
- and
- (b) an outer conduit surrounding the inner conduit, the outer conduit having at least one discharge opening at a point below the at least one discharge opening of the inner conduit, wherein wastewater flowing into the outer conduit from the discharge openings of the inner conduit will flow through the discharge openings of the outer conduit.
A wastewater treatment and dispersal system, comprising:
- (a) a septic tank;
- (b) an inlet for receiving wastewater from a septic tank and for delivering wastewater to a dispersal field;
- (c) a wastewater dispersal system comprising:
- (i) an inner conduit having a closed bottom and at least one discharge opening at a point spaced above the closed bottom, the inner conduit so configured and the discharge openings so sized and positioned that a volume of wastewater flowing into the inner conduit is retained by and will stand above the bottom of the inner conduit below the level of the discharge openings until it has a BOD of less than about 125 mg/l;
- and
- (ii) an outer conduit surrounding the inner conduit, the outer conduit having at least one discharge opening at a point below the at least one discharge opening of the inner conduit, wherein wastewater flowing into the outer conduit from the discharge openings of the inner conduit will flow through the discharge openings of the outer conduit.

A water dispersal system for a gravel-less wastewater treatment system of the type used in conjunction with a septic tank, comprising:
- (a) an inner conduit having a closed bottom and at least one discharge opening at a point spaced above the closed bottom, the inner conduit so configured and the discharge openings so sized and positioned that a volume of wastewater flowing into the inner conduit is retained by and will stand above the bottom of the inner conduit below the level of the discharge openings until it has a BOD of less than about 125 mg/l;
- and
- (b) an outer enclosure surrounding the inner conduit, the outer enclosure having at least one discharge opening at a point below the at least one discharge opening of the inner conduit, wherein wastewater flowing into the outer enclosure from the discharge openings of the inner conduit will flow through the at least one discharge opening of the outer enclosure.
