Leach Field Form and Method of Use

Abstract

A leach field form comprising: a container with an open bottom and an open top, and four exterior walls of a first height, and at least one interior wall; at least one geonet volume with an open bottom and an open top located in the container; at least one granular volume with an open bottom and an open top located in the container; and where any of the at least one geonet volumes is separated from any adjacent granular volume by an interior wall. A method of making a leach field using a leach field form comprising: digging a trench; placing a leach field form in the trench; backfilling the trench, allowing backfill to fill any granular volumes in the form; inserting geonet into geonet volume located in the form; and removing the form from the trench.

       12 . The leach field form of  claim 11 , wherein the form has a stacked I shape. 
   
   
       13 . The leach field form of  claim 11 , wherein the leach field form has an accordion shape. 
   
   
       14 . The leach field form of  claim 11 , wherein the leach field form has a box shape. 
   
   
       15 . The leach field form of  claim 11 , further comprising:
 a removable form cover, the cover configured to sit on the open top, and cover the at least one geonet volume.   
   
   
       16 . A leach field form comprising:
 an open bottomed and open topped container comprising:
 a first end wall, having a first height; 
 a front wall, having a first height, and adjoining the first end wall, with the top of the front wall and the top of the first end wall being generally coplanar; 
 a rear wall, having a first height, and adjoining the first end wall, with the top of the front wall and the top of the rear wall being generally coplanar; 
 a plurality of interior walls having a second height, and the plurality of interior walls adjoin the front wall and the rear wall with the tops of the interior walls, front wall and rear wall being generally coplanar; and 
 wherein the interior walls are configured to form at least one volume of a first width, and at least one volume of a second width, and wherein the first width corresponds to a width of a geonet volume and the second width corresponds to a width of a granular volume. 
   
   
   
       17 . The leach field form of  claim 16 , further comprising:
 a second end wall, having a first height, and adjoining the front wall, with the top of the second end wall being generally coplanar to the top of the front wall and the top of the rear wall.   
   
   
       18 . The leach field form of  claim 16 , wherein the second height is less than the first height. 
   
   
       19 . The leach field form of  claim 16 , further comprising:
 a removable cover, the removable cover comprising:
 at least one opening; 
 at least one covered portion; 
   wherein the cover is configured to lie on the top of the opened topped container with each of the at least one opening laying directly over each of the at least one volume of a second width, and each of the at least one covered portion laying directly over each of the at least one volume of a first width.
