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.

Applying ZuluGIS and ISIGR software in hydraulic calculations
of outdoor water supply systems
Summary
A comparative analysis of specialised ZuluGIS and ISIGR software packages designed for the hydraulic simulation of outdoor water supply systems is presented. The research is focused on estimating the calculation accuracy, rate of computing, and user-friendliness of the software. The methods for calculating λ, hydraulic resistance coefficient, accounting local losses, the possibilities of setting parameters and performing calculations for the representative water supply modes: the maximum, average and minimum hourly flow rates per day, maximum, average and minimum water consumption, as well as maximum hourly water consumption for fire extinguishing purposes were estimated. The results showed that ZuluGIS provided for the fast data processing and integration with the geographic information systems; however, it has limitations in model dimensions in the free version. ISIGR provides the user with possible choosing different calculation formulas to determine the hydraulic resistance coefficient; however, the it depends on the Internet connection and server infrastructure. The findings indicate that ZuluGIS is preferable for designing and analyzing complex networks, whereas ISIGR will be better for operational calculations and educational purposes. The results obtained will be helpful while choosing software for hydraulic simulation.

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.
