Integrated Approach to Optimization of Operation of the Water Supply and Distribution System of the City of Omsk

Summary

An integrated approach to the optimization of operation of the water supply and distribution system of large cities based on hydraulic modelling with the use of modern software products is proposed. A possibility of adaptation to actual conditions of calculated results obtained by electronic simulation of water supply networks is shown on the example of Omsk. The solution of this problem makes it possible to model the necessary changes in the composition and mode of operation of each of the elements of a water supply network. The result of such an approach is reduction in the accident rate at networks and energy savings at pumping stations. Methods of execution of works, means of the measurement used, sequence of measures to be taken, the results obtained and possible prospects are presented.

Developing and implementing measures on pressure normalization in the water supply system of Tyumen city

Summary

The experience of introducing pressure regulators in the water distribution network of Tyumen city is presented. The procedure of designing the network operation parameters basing on hydraulic simulation with the use of advanced software is set. The possible efficient long-term use of pressure regulators under subzero weather conditions typical for Siberia is shown. The practical experience of the equipment installation and adjustment is laid out; the specific features of the equipment operation are considered. Based on the pipeline failure number the analysis of the efficiency of the measures on the free head normalization in the network is carried out. The installation of pressure regulators in the Tyumen water distribution network resulted in the failure rate reduction and power saving at the pumping stations.

Utilities network systems: operation experience and practical proposals on development

Summary

Water supply and wastewater disposal systems in the most of the big Russian cities for more than hundred years already have been providing for public water supply and wastewater disposal and treatment which are one of the most significant blessings of civilization. At present assessing the situation with the water supply safety and determining the vector of development with account of the gained experience including overcoming negative trends that reflect different processes in the branch have been tasks of primary importance. The attempt to summarize the experience of operating water distribution networks and evaluate the current state of the industrial relations and water and wastewater services maintenance forms as well as of the prospects for the development of network systems as part of the whole branch is presented. The apparentness of the pending problems and their structural analysis using the example of solving the applied problems of reducing network accidents show the need to formulate the concept of the branch development. Only the extensive discussion and engagement of all the stake holders – business, scientific community, managers of public utilities, regional and federal officials will provide for solving the problems in the branch that have become more acute lately and that have made the residents of the Russian regions suffer most notably.
