A method for desalinating and recycling the brine exiting a salt cavern. This method reduces the overall make-up water demand to wash a salt cavern, eliminates the brine disposal well and controls the cavern growth rate during disposal operations. The method includes the steps of: a) desalinating brine emerging from the salt cavern, and creating a stream of saline water, a stream of non-saline water and a stream of salt; b) recycling the stream volumes and combining the stream of non-saline and saline water with make-up water, thereby reducing demand for make-up water, c) pumping the salinated water into the salt cavern, and controlling the rate of growth of the salt cavern while disposing of wastes in the cavern, and repeating steps a) and b) substituting the make-up water with a waste mixture.
