FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry, namely to systems for collecting water from underground and elevated sources to maintain reservoir pressure through injection wells. Siphon water intake comprises ground pavilion with vacuum pump arranged therein and communicated via pneumatic lines with vacuum tank made up of vertical well. There is an underground siphon header. It is interconnected with well. Downhole pump with pressure pipeline is lowered into this well. In the pavilion there is a sealed well embracing the well top and a drop catcher installed. This drop drip is communicated via a shut-off element with a discharge pipeline, while its top part communicates with the vacuum pump outlet. At the inlet of the vacuum pump there is an air removal device at start-up. It is communicated with the bottom of the drop catcher through the gate valve.
