An adjustable coupler interconnects leaching chambers to create a serpentine pathway for a leaching field. The coupler can comprise a mating feature, which can be used to mate the coupler between a first leaching chamber and a second leaching chamber, and an adjustment feature, which can adjust the angle between the first chamber and the second chamber between a range of angles. Either, or both, features can include a swivel connector mateable to an end of one of the chambers. The range of angles can be particularly chosen to be about 45°. More particularly, the range of angles can be about 22.5° in either the clockwise or counter-clockwise direction.
