In septic systems for handling household waste water or in clear water drainage applications, lightweight molded polyethylene galleries are used to form the drain field. The galleries can be axially aligned in end-to-end relationship with each gallery defining an interior hollow chamber. A unique latching system is used to attach adjoining galleries to one another. A perforated delivery conduit extends through and introduces effluent into the hollow chambers of the galleries where it is allowed to seep therefrom into the surrounding earth through the open bottoms of the galleries or through infiltration apertures in the walls of the galleries.
