The document discusses water resources and management in the Campos and Ses Salines areas of Mallorca, Spain. It notes that rainfall is low and water comes from underground reservoirs. A public water association called the Mancomunitat supplies some residents, taking water from three wells, while others rely on private suppliers or rainwater. Water is expensive due to low rainfall and tourism, and often salty or chlorinated. The document also covers sewage management and regulations around water pollution. Overall, it argues that overexploitation of scarce water resources has led to salinization issues, and that continued conservation efforts are needed.
