Disclosed herein are various embodiments relating generally to a system for lifting water from an aquifer formation by drilling a u-shaped well through the aquifer formation, which comprises a water well screen within the aquifer formation with an inner production string with a series of check valves within the aquifer formation that allow water from the aquifer to flow from the water well screen and into the production string while preventing the water from leaving the production string, and then uses air pressure to force the water through a larger check valve in the production string, so that it may be collected in a surface tank. When not extracting water from the aquifer formation, the system allows treated water to be pumped into the outer casing and back into the aquifer, thereby recharging the aquifer formation with water.

A system and a method of aerating well water using an aeration system comprising a well water drop pipe approximately vertically positioned having a bottom end in a well below the pumping level of the well water. Attached to the bottom end of the pipe is a submersible water pump, and a limited check valve is fluidly attached above the water pump. A flow restrictor is fluidly attached above the limited check valve to limit the flow of water up the pipe, and above the flow restrictor or the check valve is fluidly attached a bleeder to allow air to flow into the pipe when negative pressure is in the pipe. Above the bleeder is fluidly attached at least one check valve to prevent flow of water back to the bleeder.

There are provided a well curb device and a method for controlling the same. The well curb device includes: a well curb, a well cover sensor, a light sensing component and an audible alertor. The well curb includes a placing portion for placing a well cover. The well cover sensor is disposed on the well curb, and is configured to detect whether a well cover is placed in the placing portion. The light sensing component is configured to trigger the audible alertor to issue an audio alarm of a specified decibel, when detecting that the light intensity around the well curb is greater than the specified value, thereby improving the safety of the well curb device.

Disclosed embodiments concern a system and method for extracting water from a water well using a vacuum-assisted technique. Particular embodiments of the system concern using a water well with a well casing, a casing seal and a water pump within the well, and a water tank, a compressor, and a heat exchanger above ground to withdraw water from the well. In particular embodiments, the casing seal is positioned over the well casing, to which the compressor is fluidly coupled to create a reduced pressure within the well and draw water into the well. In particular embodiments, the system can be used during an entire pumping season, thus providing the ability to extract water and/or increase water extraction from the ground during dry parts of the year and/or freezing parts of the year.
