The five municipalities of Ibiza have agreed to supply themselves 100% with water from desalination plants and reduce the use of well water in municipal networks to the bare minimum. This decision was made at the Council of Mayors held at the headquarters of the Island Council, where the President of the Council, Vicent Marí, explained that more desalinated water is produced during the off-season than the municipalities consume and that replacing well water "will reduce the pressure on aquifers" by around one cubic hectometer.
