ABSTRACT:
A wastewater treatment system includes inner and outer relatively telescopic units, the outer telescopic unit including an outer container having a bottom wall and a peripheral wall collectively defining a generally upwardly opening chamber, a filter exteriorly of the peripheral wall and defining therewith a first downstream settling zone, control openings in the peripheral wall for controlling wastewater flow through the first settling zone generally in response to the level of wastewater in the first settling zone, the inner telescopic unit including an inner container having a chamber defined in part by a peripheral wall, the peripheral walls being in relatively spaced relationship to each other and therebetween defining a second settling zone, a third settling zone within the inner telescopic unit chamber, and the inner and outer telescopic units each being a distinct unitized structure which permits the same to be bodily telescopically assembled and disassembled.
