Treatment plant employs a septic tank which effects a mechanical purification stage. The encircling wall and the central shaft of the percolating filter is raised from its normal height under the purification plant's load to form an additional space filled with packing material. A rotary distributor is positioned at an appropriate height. At least part of the fine purification stage lies near to the remaining sections in the block construction.
