ABSTRACT:
A modular drain field section and a method for making a drain field section are disclosed having upper and lower casings which are connected together to form each drain field section. Both upper and lower casings have a center pipe portion which, when connected together, forms a central pipe and each casing has troughs on both sides of the center pipe portion. The lower casing troughs have a plurality of openings therein and a spillway connects the central pipe with the lower casing troughs. The modular drain field sections are connected together to form a drain field without the use of rock media, fill, drain tile, grace board or felt paper. A method of making the modular drain field section includes using the same mold both for the upper and lower casings.
