The present invention is a wastewater treatment system utilizing a recirculating filter system comprising sand, gravel, or synthetic media. Septic effluent is continuously, or approximately continuously, dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. The dosed effluent is treated and dispersed into a dispersal field using double coiled distribution lines that can alternate flow through emitters to rest the dispersal field. The double coil dispersal lines allow more emitters per unit area allowing treatment of the effluent more slowly and effectively.

A fin assembly apparatus which comprising a product dispensing stand for supporting a fabric product, a movable fin insertion apparatus for overlapping the fabric product and forming a fin opening, a movable fin sandwiching apparatus for forming a fin member, a pair of spaced apart guide tracks for supporting the movable fin sandwiching apparatus and the movable fin insertion apparatus, and a control panel for controlling operation of the fin assembly apparatus during manufacture of the fin member.

Systems, methods, and apparatuses are disclosed relating to onsite subsurface wastewater treatment systems and components thereof. Such systems may include a manifold of a subsurface wastewater treatment system. The manifold may further include a front wall and a rear wall, an internal cavity between the front wall and the rear wall, and a length. The manifold may further include one or more conduit port extending from the rear wall, a first connector port configured at one end of the manifold and defining an opening connected to said internal cavity, and a second connector port configured at an opposite end of the manifold and defining an opening connected to said internal cavity. The manifold may be incorporated into a subsystem or system for subsurface treatment of wastewater along with one or more conduits configured to receive and disperse wastewater.

Treatment of wastewater containing contaminants is provided. More specifically, treating wastewater through capture and recirculation of percolated fluid effluent through and from one or more infiltration field systems is provided.

A septic system, including a septic tank and a pipe positioned within the septic tank, is provided. The pipe receives sewage and provides a flooded, anaerobic environment for sewage passing therethrough. The outlet of the pipe is positioned inside the septic tank and is optionally spaced from the outlet of the septic tank. In operation, the sewage introduced into the pipe generally separates into a solid portion comprising sludge, which remains in the pipe, and a liquid portion, which passes through and around the sludge. In one embodiment, the septic system has an absence of a sump chamber upstream of the septic tank.

A leaching tube includes a tube base for burial in the earth to disperse or gather liquids, the tube base having a semi-rigid spiral, or helical, form with spiral, or helical, ribs, and spiral, or helical, openings along the length of the tube, a water permeable covering wrapped around the tube base, and a vertical frame inside the tube. The frame is a pipe frame that supports the spiral tube base and also provides an air conduit for air injection inside the tube. The frame is fixed to the spiral ribs on the top and bottom of the frame. End plates can be fixed to the frame by bridge pieces and pins. Sections of tubes can be connected end to end by bridge pieces and pins. The pins can be pipe pieces that can also provide air connections between the tube sections. One of the end plates can provide an inlet opening for an effluent inlet pipe.

Water treatment structures may have at least a first geotextile fabric layer; a second geotextile fabric layer; a third geotextile fabric layer; a first filler layer with plastic particles, arranged between the first and second geotextile fabric layers; and a second filler layer with plastic particles, arranged between the second and third geotextile fabric layers, wherein the geotextile fabric layers and the filler layers are within a housing, and wherein the structure is configured such that contaminated water proceeds sequentially through the first geotextile fabric layer, the first filler layer, the second geotextile fabric layer, the second filler layer, and the third geotextile fabric layer. Methods of treating wastewater may involve passing wastewater, after optional oxygenating and pre-filtering, through such alternating layers of geotextile, preferably nonwoven, and polymer particles.

Reconfigurable water leaching modules are provided herein. These modules may comprise a plurality of dosing conduits and a plurality of leaching channels fluidly coupled to the dosing conduits where the leaching channels are reconfigurable from a first retracted position to a second extended position and where the leaching channels may hang downwardly from the dosing conduits in the second extended position.

A leaching tube includes a tube base for burial in the earth to disperse or gather liquids, the tube base having a semi-rigid spiral, or helical, form with spiral, or helical, ribs, and spiral, or helical, openings along the length of the tube, a water permeable covering wrapped around the tube base, and a vertical frame inside the tube. The frame is a pipe frame that supports the spiral tube base and also provides an air conduit for air injection inside the tube. The frame is fixed to the spiral ribs on the top and bottom of the frame. End plates can be fixed to the frame by bridge pieces and pins.
