Abstract
Non-brackish water can be produced from the brackish water found in many inactive oil wells. The inactive well is perforated at the level known to have brackish water and the water is pumped out. The brackish water is desalinated producing non-brackish water, preferably, potable water. A preferred method of desalination is by reverse osmosis.
