The document discusses water resources and management in the municipalities of Campos and Ses Salines in Mallorca, Spain. It notes that rainfall is low and water is obtained from underground reservoirs. A public water management association called the Mancomunitat of Migjorn supplies running water to 5,300 people from three wells, with others obtaining water privately. Water is expensive due to low rainfall and tourism, and often salty with high chlorine levels. The sewage system began operating 10 years ago and treats waste water at three plants, reusing only 30% currently. Water overuse from agriculture and tourism has led to salinization issues.
