Description

The invention relates to water supply and concerns the constructive implementation of water supply systems of settlements from groundwater intakes.

The purpose of the invention is to increase the efficiency of the system.

FIG. 1 shows a diagram of a water supply system for settlements; in fig. 2 is a diagram of a water well assembly.

The water supply system includes water wells 1, in which water-lifting devices 2 are installed, connected by pressure pipelines 3 and a conduit 4 with a sealed container 5 having a valve 6 for air release and pressure sensors 7. Each water well 1 is equipped with a mixing chamber 8 and an aerator 9 installed at the entrance to the mixing chamber, placed in the water supply pipe 10 into the well and connected to the pressure pipe 3 by means of pipelines 1-13 with adjustable valves 14-16 installed on them. The valve 16 is made with an electric drive. On the pressure pipe 3 installed a check 17 and 18 adjustable valves. The system is equipped with a control line 19.

The water supply system works as follows.

In the initial position, all lifting devices 2 are turned on and the hermetic tank 5 is filled with water. When the working pressure is reached in the hermetic tank 5, the sensors 7 send a signal to turn off the operation of the lifting device 2 to

five

ONE of the water wells 1 and the opening of the valve 16 in the pipeline 13.- At this, the check valve 17 installed on the pressure pipeline 3 closes and underground water flows through the pipeline 11 to the aerator 9 and through the pipeline 12 to the mixing chamber 8. The aerator 9 provides intensive saturation of groundwater with oxygen in the air and, in the form of a water-air emulsion, enters the mixing chamber 8, where it mixes with the deoxygenated underground water coming from pipeline 12, and is then fed through pipeline 10 to the stopped water well 1. When pumped into the intake a well 1 of a predetermined volume of a mixture of a water-air emulsion and groundwater activates the water-lifting device 2 of the previously stopped well 1 and closes the valve 16. At the same time 7 pressure sensors

0, the control line 19 sends a signal to stop the next water well of the water supply system.

After the pumping and pumping cycles have been completed, the water supply system is ready for operation on each of the water wells.

 and begins to supply water to the consumer.

The use of the invention provides an increase in the degree of purification of groundwater in the reservoir by 20-30% due to an increase in the oxygen content in aerated water supplied to the reservoir. At the same time, the cost of water supplied to the consumer is reduced by 15–20% due to the reduction in the cost of electricity consumed by the system and an increase in the amount of water supplied to the consumer.
