The complexity of treating wastewater of small sewerage facilities lies in the small volumes of treated water, considerable irregularity of their inflow to treatment facilities, inhomogeneity of their composition by hours of inflow to treatment facilities, as well as high requirements for treated wastewater discharged usually into low-power water bodies or to the surface. The treatment facilities should exercise the functions of purifying wastewater from pollutants according to regulatory requirements. A sewerage system and wastewater treatment technology have been considered by the example of the town of Fort-Shevchenko. A technology for purifying similar wastewaters using clarifiers with a sludge blanket formed by activated sludge flakes has been proposed. This technology has been introduced at several treatment facilities in the East Kazakhstan region that are successfully operating in compliance with the technical and engineering operation requirements. The treated wastewater quality indicators are given.
