Description: Water Supply System Field of the Invention The present invention constitutes a device intended for securing regular water supply t residential premises. The problem of regular water supply has appeared to be pressing in some regions wher people live or work on a permanent or temporary basis. Water sources lacking sufficient reserve capacities cannot provide residential areas wit regular water supply. Water supply is irregular and in a number of regions there exists a discrete regime of water supply. In some regions creation of modern reliable and efficient water supply systems presents today an urgent necessity, and in the nearest future this will pose a serious problem for many other regions of people's habitation. Water plays a major role in a human body's functioning, and its shortage could cause worsening of health condition and even serious disorders. Prior Knowledge While designing water supply systems we should take into consideration average water consumption rate, i.e., 2-3,5 litres per day (See: "Problemy kosmicheskoy biologee " . torn XXIV. Chizov S.V., Siniak Y.E., "Vodoobespechenie ekipazey kosmicheskih korabley", "\ayka", M. 1973 , str. 16,17). It should be noted that in creating such systems for regions with scarce water reserves, the experience accumulated through making terrestial experiment modules for astronauts training should be taken in account as well (See: XXIV, Chizov S.V.. Siniak V. ., "Vodoobespechenie ekipazey kosmicheskih korabley", "N ' ayka", M. 1973, str. 134...149). Among those systems there is one that comprises a water source and water distribution pipeline, between which a set of filters and water quality analyzer are interlocked (See: "Problemy kosmicheskoy biologee", torn XXIV, str. 135, ris. 42) Although the existing systems have closed-type technological structure. the> can be easiah modernized by way of turning them into open s>stem utilizing a water source Basically, there are two ways of creating water supply systems: a) creation of wat reserves, b) application of reclaim processes to their (reserves) reproduction. However, intermediate integrated method should not be neglected. It means simultaneous creating water reserves and reclaimmg water drawn from sources unfit for immediate u with its further decontamination and preservation. Besides, means of water reclaim may be applied in creating water supply systems for are where water supply is m grave condition. The means and methods of wat decontamination and preservation are well developed nowadays (See "Proble kosmicheskoy biologee". torn XXIV, str.27 ..42). There exists technical specifications for a water supply system descπbed in the USS certificate N 1564294, book E 03 B 1 1/06, 1987. This systems includes, a water reservo connected with a water source through a supply pipeline and distributor pipeline, a pum a filter and water pressure and water level indicators This system does not meet all modern requirements of supplymg residential areas where t volume of water reserves and the number of water sources are reducing Its constructio stipulates rigid connection with only one water source. In case of water reserve exhaustio in this source, convertion of the system to utilizing another source would require significa efforts and cause a long water supply failure. Moreover, the system is adjusted to concrete water source havmg specific water quality properties To convert this system t using another water source, water filtering units should be reconstructed because in thi new source the water has different qualities. A system which could be regarded as quite efficient and close to solving water suppl problems is the one described in "Problemy kosmicheskoy biologee", torn XXI , S V , Siniak Y.E., "Vodoobespechenie ekipazey kosmicheskih korabley", "Nayka " , 1973, str. 135, πs 42 However, as has been mentioned above the drawback of thi technical decision is closed-type structure of water supply system with a constant wate source 7 PCMB95/00903 3 Discloser of Invention The purpose of the present invention is to improve operating capacity of water supply systems by way of stabilizing water supply through creation of water reserves to be used during periods of water supply failure. The present technical solution envisages utilizing all available in a concrete region water sources, those fit for immediate use as well as those not satisfying consumer water quality standards. Nonstandard water is supposed to be refined through special procedures to meet existing requirements. The problem is being solved due to the innovative construction of the present system. The system comprises a pipeline supplying water to a water reserve tank and a pipeline distributing water from this tank; the supply pipeline consists of intake heading, water quality analysing unit and a water preparation unit, while the distributor pipeline consists of a number of distributor appliances, control unit, a number of supplimentary intake headings, a unit of water preservation, a pump, water heaters and water pressure and level indicators. The supplementary intake headings are connected with the supply pipeline. Water quality analizers, water heaters and water preservation unit are consecutively interlocked into the supply pipeline between the water reserve tank and water distributors. Water pressure and level indicators, water quality analizers, water preparation unit and pump are connected with the control unit. Water supply system comprises pipeline supplying water to water reserve tank and pipeline distributing water from the reserve tank. The supply pipeline consists of intake heading and the distributor pipeline consists of distributor appliances, is equipped with control unit, a number of supplementary intake headings, pump, water heaters, and water pressure and level indicators. The supplementary intake headings are connected with supply pipeline. The pump is interlocked into distributor pipeline between water reserve tank and water disrtibutors, which are connected with water heaters, water pressure and level indicators and pump are connected with control unit. Brief description of drawings. The essence of the invention is presented by a drawing where Fig.1 is the water supply system block-scheme. The water supply system comprises water reserve tank ( 1), supply pipeline (2), and distributor pipeline (3). The supply pipeline (2) consists of a set of intake headings (4) connected with the common pipeline (5) a series of supply pipes provide for intaking water from various water sourcesgs. The water flowing through the pipeline (5) passes a set of water quality analyzers (6). Availability of water in the pipeline (5) is indicated by pressure indicator (7). After quality analysis water goes to a water preparation unit (8). Here there are appliances for water decontamination, filtration and demineralization. Depending on water quality test results, water drawn from some source is processed with corresponding means within the unit. From the preparation unit water goes through preservation unit (9) to reserve tank. Since water sources may be diverse including those unfit for immediate use, all water must be processed in the preparation unit (8). As the time of water supply failure can hardly be envisaged, water may be kept for as long as required in the water reserve tank. That is why the water is to be preserved, i.e., some preservatives should be added which is effected in the preservation unit (9). Preservπtion methods may be diverse including fluid, gas, electrochemichal ones. There is a water level indicator ( 10) in this tank. Distributor pipe (3) consists of pump (1 1), parallel-action by-pass pipeline (12) and a number of water distributing pipes (13) to distribute water for the consumers. Consumer water may be heated with, for instance, non contact type electric heaters (14). The water is heated immediately prior to its distribution up to the temperature required for sanitary processing, i.e. not higher than 40°C, which saves electric power. The electric water heater is interlocked prior to or after the pump. The by-pass pipeline is sed when the pump is working; when the pump is not in operating condition, and water cannot go through it. And while the centrifugal pump functions normally, the by-pass pipeline is not utilized. All the above mentioned units and components function under commands from the control unit (15). This control unit receives signals from pressure indicator (7), a set of water quality analizers (6), and water level indicator (10). The control unit analyses the received signals and gives commands depending on the immediate water intake situation. If intaking water is effected normally, water passes all the stages in the supply pipe (2), and further water reserve tank (1) on its way to customers. The reserve tank is permanently filled up. If there occurs water intake failure, the control unit produces an information signal and switches the pump to supply consumers with water from water reserve. According to such information signals, the personnel or automatic devices can switch water intake over to another water source. This water supply system may be used with other set of components. When water of satifactory quality be drawn from available sourses, water quality analizers (6), unit of water preparation (8) and unit of water preservation (9) (Fig.2) may be excluded from the system. In such a case the control unit (15) works without signals on water quality. Industrial use of the invention The present system secures regular water supply to residential premises under conditions and in areas with scarce water supply. The system envisages intaking water from several sources to be furtherly reserved in tanks. The sources may be diverse, since the available means of water preparation allow to improve water to be utilizable, be it water drawn from sea, lakes, ponds or contamitaned sources. The system's ability to draw water from diverse sources allows to reduce or to the time of water supply failures.
