Abstract

The paper presents basic vacuum sewerage systems and average unit electric energy consumption according to the literature data and own research. It was found that the energy consumption of vacuum sewage systems is relatively high (200-400 kWh/a per one connection), but highly diversified (from 0.2 kWh/m3 to several kWh/m3), which indicates great opportunities for its reduction. Four areas of transport cost reduction were specified: concept, design, construction, operation and maintenance. All these areas may, to a certain degree, determine the installed electric power and energy demand for the transport of wastewater in a vacuum sewerage system, but the greatest effects can be achieved by improving the energy efficiency of vacuum pumps and controlling the opening time of vacuum valves.
