ABSTRACT:
Effluent is pumped into a first multistage, modular, vertical filter that extends from ground level to depth near or at the water table. A fluid accumulator, located at the bottom of the filter, accumulates water from the filter stages. The water in the accumulator is pumped into the surrounding soil by pressurizing it from a ground level pump. Fluid that accumulates around the filter is removed for irrigation. The filter and accumulator are removed as a single unit from well shaft for servicing.
