The use of advanced pipe accessories as a method of reducing water losses and improving energy efficiency

Summary

The reduction of physical water losses alongside with the improvement of water distribution energy efficiency is an important challenge both in Russia and all over the world. Described in the paper is the method of water losses reduction developed by the International Water Association (IWA) on the basis of four directions of activities, i. e. pressure control in the distribution network; leak detection and elimination; routine maintenance, repair and rehabilitation of the fittings and pipes; prompt elimination of distribution network failures. Comprehensive activities in the abovementioned fields allow reducing water losses to an economically acceptable level. Simple and efficient measures are replacement of valves and fittings as well as introduction of advanced safety valves, repair accessories and pressure control valves in the distribution network.

Key words

energy efficiency , valves , shut-off and control valves , reduction of water losses , pipeline repair , pressure control in the distribution network
