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.

Integrated approach to reducing water losses in Tyumen

Summary

Sustainable and integrated water resources management is one of the important challenges of the present. Access to clean water in the world is limited, in some regions there is an acute shortage. Supplying clean water in the required quantities and quality is becoming a priority for policy makers and water industry professionals worldwide. Reducing the expenditures of the resource providers, improving the efficiency of water treatment processes are those internal resources that can provide for the sustainable development of the enterprise, in a down economy in particular. The main line of «Tyumen Vodokanal» LLC activities, key elements of the operations, and insights are presented. Over the past five years Vodokanal of Tyumen managed almost to halve the water losses – from 31.7 to 16% while increasing the length of the maintained water distribution networks by 27%.
