Along with the therapeutic climate and medicinal mud, mineral water is one of the resort's main natural therapeutic resources. Mineral waters from Svetlogorsk springs are predominantly sodium bicarbonate-chloride waters with elevated iodine and fluoride content and are used for drinking therapy. Bromide sodium chloride brines are used for balneological procedures. The mineral-water pump room opened in 2010 and belongs to the Svetlogorsk Military Sanatorium. In 2024, the city also has a municipal pump room on the seaside promenade near the Zodiac sundial.
