METHODOLOGICAL BASES FOR ASSESSING THE ENVIRONMENTAL IMPACT FROM THE INTRODUCTION OF A FREQUENCY-CONTROLLED ELECTRIC DRIVE AT PUMPING STATIONS OF WATER SUPPLY AND SEWERAGE SYSTEMS

Abstract

A methodology for determining the environmental impact indicators from the operation of centrifugal pumps of water supply and distribution systems (WSDS) and wastewater pumping systems (WPS) is presented. The main dependences are given that allow calculating the cost of standard fuel for the process of pumping water and wastewater and the level of greenhouse gas emissions in CO2 equivalent. The dependences of determining the level of leaks due to the excess of the calculated pressure in the water distribution system are also given. Recommendations are given for the practical application of the methodology in the implementation of energy-saving and environmental measures at the pumping stations of the WSDS and WPS.
