Solar Salt Production is the process in which naturally occurring salt water (from a sea, lake, etc.), is channeled into a series of shallow, interlocking ponds. Over time, the water moves through the sequence of ponds that allow evaporation of water to create brine solutions until the most saturated brines evaporate to form salt crystals.
