Abstract:
A method of constructing a biological waste water treatment and disposal system, comprising the steps of:(1) installing a primary waste water treatment mechanism; (2) excavating a site for a secondary trickling filter area and a tertiary disposal bed downstream from the secondary trickling filter area; (3) constructing a containment housing having an intermediate wall therein between the secondary trickling filter area and the tertiary disposal bed; (4) stacking a plurality of trickling support structures withing the secondary trickling filter area of the containment housing; (5) filling the plurality of trickling support structures with a predetermined quantity of primary filter media; (6) surrounding and overlying the plurality of trickling support structures with a predetermined quantity of secondary filter media; (7) layering a predetermined quantity of secondary filter media in the tertiary disposal bed; (8) constructing a distribution manifold adjacent to and overlying the plurality of trickling filter support structures, and attaching the distribution manifold to the primary waste water treatment mechanism; and (9) passing pre-treated waste water through the distribution manifold, onto the plurality of trickling filter support structures, through the primary filter media and the secondary filter media, and into the tertiary disposal bed.
