Abstract
A wastewater disposal system in which wastewater is transported to an elevated site on a hill, distributed along a predetermined width of the hillside and allowed to flow down the hillside under the influence of gravity. The rate of distribution of wastewater is controlled so that it does not completely penetrate the hill and does not accumulate to any significant degree at the hill bottom. Beneficial uses of the wastewater are disclosed, as is treatment of the wastewater, both biological and phyto treatment.
