The method of replenishing a body of fresh water with distillate of water vapor derived from a body of salt water, comprising: spraying salt water from the body of salt water into a first chamber elevated above the body of salt water and connected by a first conduit, filled with water, extending from the bottom of the first chamber into the body of salt water to maintain a subatmospheric pressure in the first chamber to vaporize the salt water spray; feeding the resulting vapor into a second chamber elevated above the body of fresh water and connected by a second conduit, filled with water, extending from the bottom of the second chamber into the body of fresh water to maintain a subatmospheric pressure in the second chamber; and spraying fresh water from the body of fresh water into the second chamber to condense the fed vapor so that the condensed vapor flows through the second conduit to the body of fresh water.
