Wells for drinking water extraction and methods for extracting drinking water from a well

Abstract

The invention relates to a well for drinking water extraction comprising a drinking water supply device, a water outlet nozzle, a collector for water from the outlet nozzle, and a water discharge device from the collector. The supply device includes a line from a supply line to the water outlet nozzle. The line to the supply device branches into at least two branch lines, the first and second branch lines of the supply device each having one or more valves, at least one of which is a solenoid valve. A switching device is provided, which is designed to control a time-delayed opening of the solenoid valves relative to each other. The second branch line has a lifting mechanism. Furthermore, a connecting line with a check valve is provided, which leads from the second branch line to the first branch line in a section upstream of the lifting mechanism.
