In the article the authors offer their suggestions for improving the reliability of the standardization requirements for water supply facilities in Vietnam, as an analog of building regulations of Russia 31.13330.2012. In Russia and other advanced countries the reliability of the designed water supply systems is usual to assess quantitatively. Guidelines on the reliability assessment of water supply systems and facilities have been offered by many researchers, but these proposals are not officially approved. Some methods for assessing the reliability of water supply facilities are informally used in practice when describing their quality. These evaluation methods are simple and useful. However, the given estimations defy common sense and regulatory requirements used by all the organizations, ministries and departments, for example, of Russia, in the process of allowances for restoration and repair of water supply facilities. Inadequacy of the water supply facilities assessment is shown on the example of assessing the reliability of pipeline system. If we take MTBF of specific length of the pipeline as reliability index for a pipeline system, for example, 5 km, a pipeline of the similar gauge, material and working conditions with the length of 5 m, according to the estimation on the basis of non-official approach, must have a value of MTBF 1000 times greater than with the length of 5 km. This conclusion runs counter to common sense, for the reason that all the pipes in the area of 5 km are identical, have the same load and rate of wear (corrosion, fouling, deformation, etc.). It was theoretically and practically proved that products of the same type in the same operating conditions (excluding determined impact of a person), work as an entity, which MTBF is equal to the average lifetime. It is proposed to take the average service life as a reliability indicator of a pipeline. Durability, but not failsafety of the pipe guarantees pipeline functioning. It is proved that not a specific pipeline length should be taken for an element of a pipeline system, but the repair area, which is in two sides limited by isolation valve and is completely disconnected for the time of recovery or any other need.

Pipeline from an external system should be inlet in the part of the building where a large number of water folding devices will be concentrated. As a rule, for shopping cen- ters with a lot of water consumers it is necessary to make not less than three inputs, each of them should be connected to different areas of an external ring water supply system in order to make the work of the system more reliable.The places for water folding fittings in shopping centers are the following. The water folding devices: mixers are placed in sanitary cabins of shopping centers. Usually, for for water saving in buildings with a big pass-through capacity per hour it is reasonable to use contactless mixers, which are turned on upon raising a hand with a help of motion sensor or light sensor. Another important argument in favor of such mixers is prevention of infections spread for the reason that the consumer doesn't touch the device, so, the risk of bacteria transmission via the device decreases. Such mixer supplies water with a demanded expense and temperature. As a rule, water for such mixers moves from the centralized internal water supply system of hot water, mixing up with cold water. If there is no centralized hot water supply system, it is possible to use hot water storage heaters in case of a small number of visitors or to reject mixers at all in favor of the cranes giving water of only one temperature (cold), which is also practiced.For the branch of economic and household the water receivers are used, which are present in sanitary cabins in most cases by toilet bowls, wash basins, urinals.

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.

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.

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 recommendations for the development of additional regulatory requirements to reliability of water supply systems in Vietnam are offered. In current construction rules for design, the reliability of water supply systems of water facilities is not standardized. Water systems are classified into three categories, for which the conditions for performing functions in the process of water supply for consumers are formulated. It is not provided to assess the quality of these functions quantitatively. Adoption of design decisions without quantitative assessment of their quality is violating a systematic approach in carrying out construction and design works, which has formed in the global practice. As a result of the research of water supply facilities’ reliability in Vietnam and Russia, the reliability of the existing water supply facilities has been estimated. On the basis of mathematical methods for assessing the reliability of technical objects, the methods for assessing the reliability of water supply facilities and their systems has been justified and systematized. If there is lack of reliability and security requirements to the object of capital construction for design documentation development or such requirements are not established, the development and approval in the prescribed manner of special specifications should precede the documentation development. It is proposed to systematize the statistical data gathering on the reliability of the equipment and facilities of water supply systems by uniform rules. Any designed objects of water supply must have a quantitative estimate of the level of reliability. The outlined methods for assessing the reliability of water supply facilities and systems can be used in the formation of regulatory requirements for reliability in the design of water supply facilities in Vietnam.

In the article the requirements for fire safety assurance are justified for the objects, in which water is supplied with account for serial and parallel area zoning. In the process of zoning the district is segregated into such parts, for which head rate in any point of selection of water from network will not exceed 6 bar. In the current regulatory rules the requirements for the calculation of the costs of water points are stated, as well as in case of extinguishing fires at the sites with water-supply systems zones. It is recommended to analyze each zone of the system of water-supply separately, without interrelation with the common water feeders, water consumers and services of fire extinguishing. Such an approach to assign water discharge for fire extinguishing results in the decrease of fire safety of an object, deforms calculation technique of outside systems of water-supply of the similar-type objects located in different parts of the terrain. Taking the number of fires and water consumption for fire suppression by the number of residents in each zone, we thus underestimate the capacity of the pipeline system. It is offered to make changes in Norms and Standards in force on fire safety of settlements. The recommendations on regulation of the number of fires and water flow for fire fighting in residential objects with zoned systems of water-supply are formulated.
