Hydraulic model for monitoring and control of the Tumen public water supply operation

Summary

Geographic information technologies allow facilitating significantly the task of operating the public water supply of an urban. In Tumen designing a hydraulic model of the water distribution network operation on the basis of «Zulu» program-design package has been carried out since 2006. The system is aiming at improving the quality, reliability and energy efficiency of the water supply and distribution operation. At the initial stage an integrated design scheme of the major water mains was developed. This hydraulic model provided for developing and implementing a number of important measures for the optimization of the water distribution network operation mode in Tumen. To improve the accuracy the model was further detalized by adding pipelines to every customer into the design scheme. At the same time pipeline certification started with recording results in the geographic information system. Calibration of the detailed hydraulic model was carried out on the basis of the information obtained from 530 pressure gauges installed at the residential service connections. The carried out calculations were noted for high accuracy (to 0.3 atm deviation). With the help of the detailed hydraulic model the following tasks are being accomplished in «Tumen Vodokanal» LLC: changing the operation modes of the pumping stations, planning water mains outage, determining technical possibility of connecting new objects. Basing on the calculations in 2011 a project of installing 24 pressure control valves in the water distribution network was implemented. The geographic information system is noted for the function of using map layers of tile-servers in Internet, as well as for possible data storage and failure analysis. The information obtained in the process of using the detailed hydraulic model is widely used by the distribution network operating service of «Tumen Vodokanal» LLC for the team task description and determining gate valve closure pattern.

Urban utility infrastructure and digital technologies

Summary

Integration of all the trends of software development in the process of digital transformation will provide for establishing a uniform highly reliable urban IT environment. The use of digital technologies will result in the elimination of the negative impact of human factor on the operation of the utility systems. By the electronic model of the water supply and wastewater disposal systems the mathe­matical model of these systems is meant assigned to the city base map with account of the cadastral territorial divisions and designed for the imitation simulation of their operation modes. The structure of the utilities layer in the specialized geographic information system (GIS) is developed automatically with the formation of the layer objects and modes of their operation. The process of plotting utility networks on the city map has been automated to the uttermost. At that a topologically fixed network graph is developed with the bridging of the relative data bases to each object. It is advisable to incorporate the electronic model of the water supply and wastewater disposal systems into the uniform urban information system with a common base map, common address database with the separation of user access according to the operator profile. The rough estimate of the efficiency of introducing the software can be carried out by the expenditure estimates. Using the expenditure estimates the economic benefit will be calculated to some tolerance, however, it will provide for evaluating the benefits and necessity of purchasing the software.

The use of geographic information systems in the Rostov Vodokanal operations

Summary

The efficient operation of water supply systems in the cities is impossible without using advanced geographic information technologies. They provide for accumulating and organizing significant amounts of the daily incoming data that characterize the process and energy parameters of different equipment at the water and wastewater facilities – from water intakes to effluent outfalls. The information from 44 master control points, 80 water pumping stations of the first through fourth stages, potable and process water meters, meters of the effluent discharged into the surface water bodies is acquired in real-time mode. Processing this information, controlling and adjusting 45 pressure control valves and other work related to maintaining the set process flow pattern at the water and wastewater facilities located on the territory of more than 34,850 hectares require reliable assistants. These particular assistants, ZuluHydro and ZuluDrain home-made systems, are used by the engineers and technicians of «Rostovvodokanal» JSC in their routine work. The practical use of the processed information in the analytical and operational activities significantly reduces the time for making technologically correct decisions and provides for obtaining real benefits in the form of reduced energy costs and saving in material resources consumption.

Designing an electronic model of water supply and wastewater disposal systems and model implementation by the example of a Russian city

Summary

Basing on the requirements set by the Russian legislation the development of the water industry and municipal utilities infrastructure shall be implemented in accordance with water supply and wastewater disposal plans. In case the city population exceeds 150 thousand inhabitants these plans shall include electronic models of water supply and wastewater disposal systems. The practical experience of «MosvodokanalNIIproject» JSC in the field of designing water supply and wastewater disposal plans for Russian cities shows that designing a proper electronic model requires significant scope of information including topological data for all the existing pipelines, geodesic marks of the pipelines, water consumer and pump characteristics, etc. Full data acquisition and displaying in electronic format can take a lot of time. In case the operator of the water and wastewater systems does not have a detailed electronic model at the first stage usually a decision is made within the frames of water supply and wastewater disposal systems engineering to design an enlarged version that will provide for estimating and analyzing the operation of water mains, main pumping stations and regulation facilities. Further on, based on the model analysis and approbation and on the city Masterplan and urban infrastructure the prospective models are developed. The experts of «MosvodokanalNIIproject» JSC successfully designed electronic models of water supply and wastewater disposal systems of Ufa, Irkutsk, Penza, and Orenburg. The experience of designing an electronic model of water supply and wastewater disposal systems by the example of a Russian city is presented.

Tools for developing schemes and electronic models  of water and wastewater networks

Summary

RF Government Decree No. 782 «On water and wastewater schemes» together with the applicable Rules specifying a number of provisions of Federal Law «On water supply and wastewater disposal» are considered with relation to the problems that water companies are facing in the process of its implementation. Developing electronic models of water and wastewater systems is a task of the companies that are directly responsible for providing these services. Comparing to electronic models schemes are more general information structures. Models serve as data sources for scheming and allow predicting network development. In the process of data transfer from electronic models to network schemes the use of identical software is sufficient. To solve this problem geographic information systems that are optimal for making an inventory of the network elements are most appropriate. Herewith the software for math modeling shall be able to import the available data. The direct use of the imported model in calculations is possible only if we have relatively small-sized networks. For network model building it is reasonable to use specially configured software which is of prime importance for big cities. When choosing the software special attention shall be paid both to the possibility of communicating with the geographic information system at the data level and to the availability of means to provide for the adequacy of calculation models and simulated networks.
