Domestic sewage treatment plant or ecological septic tank

Abstract

In areas with scattered buildings and a low population density, the sewage management infrastructure is underdeveloped. Until recently, the only practical solution was to make a non-effluent and tight tank: a septic tank, which was one of the means to carry sewage away from detached houses in areas without sewage systems. Currently, domestic sewage treatment plants are highly popular. The paper shows the operating principle of a septic tank and a domestic treatment plant and analyses their advantages and disadvantages. Particular attention was paid to the economical aspect.
