Revisiting the operation of large-scale hydroegineering facilities
Summary
Unique hydroengineering facilities built in 1960–1980-ies in the USSR for the purpose of water supply, electrification and amelioration are described. Proposals on improving the design, construction and operation of the hydroengineering schemes are presented. The problems in operating large-scale hydroengineering schemes conditioning the need to conduct scientific research works and, consequently, additional capital and operational expenses are substantiated. At present because of numerous technogenic threats and natural disasters the following tasks have to be fulfilled: ensuring the safety of water reservoirs in case of seismic events; reliable operation of the hydroengineering facilities (large-scale pumping stations, hydroelectric power stations, water reservoirs etc.) under the conditions of the widespread water level decline in the rivers; upgrade and equipment replacement at the hydroengineering facilities. Involving graduate students from technical higher educational institutions in processing the data obtained for the long-term operation of the large-scale hydroengineering schemes with the purpose of gaining professional skills is proposed.

The appraisal of the technical state and operation reliability of waterworks
Summary
The results of evaluating the technical condition and reliability of waterworks carried out by NII VODGEO OJSC Center of Expertise are presented. Most typical violations and drawbacks revealed during the expert appraisal of the safety statements of the waterworks technical state and operating conditions are identified. The lack of monitoring the environmental impact of waterworks is particularly noted. A set of actions on eliminating the revealed drawbacks and improving the safety level of waterworks is suggested.

Advanced local warning systems
Summary
Until recently Ekaterinburg «Vodokanal» MUE has been using outdated equipment of the population warning systems with worked out operational life. In this connection it was decided to carry out capital upgrade of the operating warning systems. The settings of the local warning systems provide for monitoring any potential threat at every facilitity and timely warning the persons in charge and population in case of emergency. Beside recording the critical situation and transferring the relative signals the local warning systems can receive signals from other warning systems, compile and store the algorithms of controlling the warning systems at local and facility levels, control the progress of scenarios of population and persons in charge warning and informing, display the state of the communication between the soft-and hardware warning control complexes and connected systems of monitoring dangerous natural and technogenic emergency situations and potentially dangerous objects, public informing systems etc. At present the system of recording and warning about emergency situations all the interested services at the facilities of Ekaterinburg Vodokanal is meeting all the regulatory requirements set to the safety assurance in the process of operating dangerous projects.
Key words

Ekaterinburg public water supply development strategy
Summary
The strategic plan of Ekaterinburg «Vodokanal» development has been compiled as part of the city master plan. Ekaterinburg «Vodokanal» MUE is one of the designers of the «Development of the water sources, water and wastewater treatment facilities» strategic project. The project provides for upgrading water mains, street and district water networks under reconstruction; constructing new water networks for connecting (utility connection) capital construction projects to the public water supply, as well as constructing and upgrading pumping stations supplying water to the customers. The measures on construction and upgrade of water distribution networks take into account the stages of transferring to the closed hot water supply scheme (in accordance with the heat supply scheme). The set of measures is provided to reduce leakages and illegal water use by introducing the system of on-line monitoring, using special technical devices to detect illegal water connections, organizing consumer education. The project part related to the development of the public water supply is considered in detail.
