Sewage treatment plants were built in the 70s of the last century.Household effluents mostly do not reach sewage treatment plants and drain into the soil. The old sewage treatment plants are in an emergency condition. All household effluents were discharged directly without cleaning into existing storage. There is no anti-filtration screen in the accumulators, and the adjacent territory is flooded. The old CBS created an unfavorable sanitary-epidemiological and environmental situation in the project area.
