Abstract
A single-cell wastewater treatment and reuse system designed for wastewater flows of less than 1,500 gpd includes a wastewater treatment cell having a volume in the range of about 14 to about 42 times average daily discharge from a wastewater source, such as a residence, and an overlying reclaimed water storage volume which, for one temperate location, is sized to store about 120 days of reclaimed water. An end of an air conduit disposed in the treatment cell at an elevation higher than the cell bottom but substantially lower than a top margin of the treatment cell provides 2,500 cubic feet per pound of introduced biomass. A pump is operated to selectively withdraw reclaimed water for a beneficial use such as plant irrigation.
