Substantiation of the efficiency of installing emergency storage tanks at wastewater pumping stations

Summary

Improving the reliability of wastewater disposal systems is provided by measures that prevent the intrusion of raw wastewater into the ground and spills onto the land surface. Such measures include backing up pressure and gravity pipeline sections of the network, using their accumulating capacity and installing emergency storage tanks. Based on the life cycle cost assessment, studies of the effectiveness of using emergency storage tanks at wastewater pumping stations were carried out. It is shown that with a certain length of pressure pipelines of two or more strings, the option of installing emergency storage tanks may be most economically viable. As a result, dependences of the efficiency of installing emergency storage tanks on the pressure pipeline length and pumping station capacity were obtained. For wastewater disposal systems in Irkutsk, all wastewater pumping stations are divided into two groups with emergency storage tanks and two pressure pipelines. The results of the study will be useful in updating the scheme for the development of the water supply and wastewater disposal systems of the city.
