Abstract
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.
