Supply system

Water is the basis of life on earth: it is used by humans for drinking, cooking, and other household needs. Any water supply system must provide consumers with the necessary volumes of water of a certain quality, as well as have sufficient reliability.


In urban conditions, water supply is carried out through a complex branched system. It is a complex of structures that includes a source of water intake, treatment facilities, pumps, water storage tanks and a distribution network of pipes, various fittings, filters and other devices.

Water supply can be individual, or Autonomous, and centralized. In the first case, a well or well is used for water supply, and the water supply is provided by a pump. In the case of centralized water supply, water is supplied from the main pipeline, which provides the appropriate pressure.


The Autonomous water supply system includes a well, a pump, and an automatic water supply control unit. The pump supplies water from the well under pressure to the water supply system. At the same time, the hydraulic accumulator is filled with water. When the upper pressure threshold is reached (about 4.5 bar), the pressure switch turns off the pump, the water supply stops, and the check valve prevents water from draining back into the well. With a minor disassembly (for example, opening one tap), water first comes from the accumulator (without turning on the pump), its flow does not lead to the pump being turned on, but is covered with water displaced by compressed gas. As the water is consumed, the system pressure gradually drops to the lower pressure threshold (1.5 bar). Then the pressure switch turns on the pump, and the water supply from the well resumes.

Water supply from the existing water supply network is undoubtedly easier than building a well or well. To do this, you need to get a permit and Technical conditions for connection in the company that is responsible for the water supply and is engaged in its operation.

Installation of water pipes, as a rule, is carried out from the nearest well. In this case, the outer part of the inlet pipe is laid at a depth below the ground freezing point (about 1.5 m). And in the building itself, it should be located in a dry and warm room (in the basement or on the ground floor) . Technical conditions are a document that defines the places and schemes of possible connection, the depth of the laid pipeline, the diameter of the pipes and the guaranteed head at the inlet.
