In the nearest future, water consumption rate is to be reduced to 160 litres per person per day in Moscow. Water consumption reduction can cause reduction of the water flow velocity, deterioration of organoleptic properties of the water and cause flavours, odours, turbidity and colourity. The solution may consist in the narrowing of the network diameter, especially in those sections that need urgent renovation, including trenchless renovation. It will accelerate the flow velocity and ensure pre-set sanitary and hygienic properties of the water. However, narrower diameters can affect fire water flows that constitute the subject matter of this research.The authors provide the research findings based on the automated hydraulic, technical and economic analysis of loop water supply systems performed through the employment of alternative renovation methods, modeling of a water supply network on the basis of existing diameters and on the basis of diameters reduced by grades 1 and 2. It is proven that water consumption reduction accompanied by the pipeline diameter reduction by one grade doesn’t cause deterioration of any hydraulic properties; rather, itaccelerates the water flow velocity and doesn’t cause any failure to comply with effective water supply norms applicable to fire extinguishing.The authors present their original method of identification of the optimal option for trenchless renovation of pipelines and their analysis of annual energy savings.

Energy saving is a top-priority task for any country. Presently, power engineering and its relevance grow year after year. The problem accrues particular significance in the following two cases: in the event of energy resources deficiency or in the event of adverse climatic conditions in a country. For example, in some regions of the Russian Federation, where the lowest outside temperature can reach 50 °C and below during the cold season, heat losses for heating systems can exceed 50 % of the heat supplied by heat sources.Thermal insulation is a universally recognized effective method of control over heat emissions into the environment. The authors present the performance of a liquid thermal insulation applied to the surface of a pipeline. Infrared thermometry devices (a pyrometer and a thermal imager) and classical equations of the steady-state heat transfer are applied to analyze the efficiency of advanced methods of heat insulation. The authors present a graph of linear heat loss for a steel pipeline depending on the thickness of the thermal insulation layer. Images, generated by the thermal imager, are analyzed together with the data obtained by the pyrometer. They demonstrate a gap between the temperature of an isolated section of a pipeline and the temperature of the unpainted pipeline, which is equal to 5—10 °C.The authors also present a histogram characterizing the annual fuel consumption (in standard measurement units) depending on the thickness of the heat insulation layer. The findings have demonstrated that 1 mm layer of thermal isolation saves 126.1 m3 of natural gas per one running meter of a pipeline a year, which is equal to approx. 500 rubles (in prices of 2013). The payback period this energy-saving project should not exceed six months. It is noteworthy that the increase of the liquid thermal insulation layer is not a criterion for its economic expediency. If the thickness of liquid thermal insulation is equal to 1 mm, fuel savings will reach approx. 65 %; if it goes up to 1,5 mm, fuel savings go up by mere 8 %.The paper demonstrates the authors’ findings in terms of the heat conductivity declared by the producer. Some problems remain unresolved, including the issue of identification of the properties of liquid heat insulation, if the heat insulation layer is exposed to external factors (such as the temperature and humidity of the environment, heat transfer temperature), etc.

A water supply system of a special purpose is a necessary element in hot and cold shops of the industrial enterprises, office buildings and the medical centers, and also other rooms. The water supply systems of a special purpose, which give subsalty, sparkling water and water sated with oxygen, allow people to prevent, for example, strong dehydration of an organism, which is possible at big losses of water, especially in case of the people working in hot shops. Various elements of special drinking water supply system are given in the article, their main functions are described. Different types of the water folding devices pumping water to consumers, one of which is drinking fountain, are considered. Possible systems of water filtration, which can be established for quality improvement, are transferred. Among them the great role is played by membrane technologies and the return osmosis, which is widely applied now. Today there is a possibility of construction, both the centralized water supply system of a special purpose, and local. Besides, the least is a more preferable option taking into account capital expenditure for construction and operation, and also it can lead to solid resource-saving as a result of the electric energy saving going for water heating in heaters. Automatic machines of drinking water for a local water supply system of a special purpose have indisputable advantages. They are capable to carry out several functions at the same time, and also to distribute water to consumers. It allows placing all the necessary equipment, which will be well in harmony with the environment in their small and compact case, and will fit into any difficult interior of the room. Also they are very easily connected to the systems of an internal water supply system by means of a propylene tube that allows to change their sposition in space and to transfer to any place of the room with fast installation of equipment. Also the ecological effect was proved upon transition from coolers on machine guns of drinking water that allowed refusing the order of plastic bottles, which after use start accumulating on dumps, polluting the environment.

The authors consider varied engineering actions aimed at the protection of pipelines from developing erosion processes with a focus on the conditions of northern regions. Engineering solutions, considered in the article, include prevention of erosion processes along pipelines, protection from suffusion, protection of extended areas having the limit value of the slope angle, and actions aimed at the drainage of areas along pipelines. Prevention of erosion processes along pipelines consists in the restoration of the fertile layer using biological methods, as well as the volumetric soil reinforcement using geological grids. Prevention of suffusion processes consists in the employment of various types of suffusion shields accompanied by the application of geotextile. Berms are constructed as suffusion prevention actions in extended areas having a limit value of the slope angle. This action is used to reduce the water flow energy of drainage ditches and trays along the pipeline. The authors believe that a complete geotechnical monitoring network must be designed and developed to monitor the condition of pipelines and foundation soils.

Operation of present-day water supply networks and management of hydraulic models of pipeline networks are labour intensive and ambiguous tasks requiring a sophisticated approach. Operation of water supply networks servicing major Russian cities is accompanied by processing of extensive amounts of information; moreover, some elements of the water supply infrastructure are hidden under the ground. Nowadays operators of water supply networks take advantage of the advanced software used to solve a wide range of tasks associated with data filing, overall evaluation, analysis and optimization of the most important parameters of urban water supply networks. The above software is an essential tool in the management of water networks in major cities. Their ability to collect and process all data on water supply networks and to conduct some research aimed at the improvement of various parameters of the system, including optimization of hydraulic characteristics of the pipeline is employed by researchers and water pipeline operators.The authors analyze and compare CAD software systems designated for water supply networks servicing big cities, capable of resolving multi-component problems and ensuring the reliability of water supply systems.

The article contains summarized results of the research into developed software programme capable of processing findings of hydraulic experiments held at pressure pipelines (protective coatings). The authors describe the algorithm of the analysis procedure, sequential analysis, mathematical and hydro-mechanical modeling of the process of transformation of hydraulic values. The authors provide their concept of the dialog box and description of input and output information, as well as functions of the software programme at intermediate stages of the hydraulic analysis. Basic input information supplied into the hydraulic analysis software programme includes the pipeline, its inner diameter, length, and acceptable roughness error.Whenever a user presses the “display result” button, interim information is displayed on the screen and, if necessary, a set of output information is provided in the form of tables and graphs. The choice for the optimal solution is made on the basis of the minimum margin of error between experimental and analytical values of the pipe roughness.The findings may be useful to researchers involved in the study of hydraulic characteristics of pipelines made of various materials and to designers and builders engaged in renovation of sections of pipelines.

It has been known that the use of karst stability categories classified by sinking diameter and the rate of its occurrence creates contradictions between researchers and designers. These contradictions are most discernable when implementing special projects such as construction of linear objects. The article provides an example of risk management when placing linear objects on karsted territories as exemplified by trunk line submerged crossings in a valley of a large transit river. The conditions of the regional karst development were identified, as well as the features determining sink risk. The authors provide the factual material analysis using the concepts that describe the reasons for the formation sink mechanism. The risk assessment is carried out during the analysis of necessary and sufficient conditions for the occurrence of sink mechanisms forming the karst hazard. The research results showed that the seasonal variations influence the possibility of karst risk. It is proposed to use an algorithm of karst management based on the variability approach, taking into account the changes in environmental conditions that affect the essence of the danger existence.
