The Govern has allocated 2.96 million to the emergency actions carried out after the floods in Ibiza. As reported by the Conselleria del Mar y del Ciclo del Agua, the conseller of the branch, Juan Manuel Lafuente, has presented in Ibiza the balance of the emergency actions carried out on the island after the floods recorded between September 30 and October 16, 2025.
The total amount of 2.9 million euros is divided into two main blocks. On the one hand, 1.7 million euros for the recovery of the affected watercourses and, on the other hand, 1.1 million euros to restore the operation of the sewerage, purification and supply system, severely affected by the dana.
Councilor Lafuente explained that the objective of all the actions was to “restore hydraulic safety, drainage capacity and the functioning of the island’s essential infrastructures in the shortest possible time” and added that “coordination between the Government, the Council and local councils has been fundamental to intervene quickly at all the damaged points”.
Repair of watercourses
The actions carried out by the General Directorate of Water Resources have focused on restoring the drainage capacity of the Ibiza and Sant Josep torrents and repairing the damage caused by the accumulation of sediments, the displacement of walls and the dragging of materials.
In the municipality of Ibiza, one of the most critical points has been the torrent of sa Llavanera. In its central area, the flood dragged a large volume of debris that concentrated at the mouth located at Avenida 8 de Agosto.
The EMU carried out an initial emergency intervention, but it was necessary to complete the demolition of the existing roof to allow the complete cleaning of the riverbed and to rebuild the wall affected by the impact of a large pipe that had become embedded in the structure.
On the east branch of the same torrent, the ramp of the Brisol building, whose presence significantly reduced drainage and was one of the factors contributing to the overflow, was demolished. The intervention has included the construction of a pedestrian walkway to maintain connectivity and the repair of damaged pavements and paving.
Also in Ibiza, work has been carried out on the access to the old sewage treatment plant, where the accumulation of loads left the passage unusable and reduced the section of the riverbed. The bottom has been leveled, the lateral walls have been reinforced and a hydraulic closure has been provided to allow maintenance access.
Another point affected was the torrent d’en Capità, both in the section des Prat de Vila and in the industrial area of Can Bufí. In both cases, cleaning works have been completed, removal of materials, repair of damaged elements and conditioning of the connections with the drains that empty into the port, with special attention to the operation of the ‘feixes’ of Prat de Vila, where the accumulation of sediments had altered the historical channels.
At the construction site of the ses Vinyes torrent, under the EI-300 road, the flood left a large amount of material that reduced the section of the infrastructure. The UME cleared the entrance, but it was necessary to complete the removal of the material accumulated inside to ensure proper drainage.
In Sant Josep, the work focused on Begònies street in Playa d’en Bossa. The intense accumulation of water left the storm outlet unusable, so the outlet was rebuilt, a sandbox was installed to facilitate maintenance and the affected pavements were replaced. In addition, action was taken in the Es Jondal torrent to remove a large tree that was obstructing the channel.
Lafuente emphasized that these interventions “make it possible to recover the hydraulic capacity of all the affected points and reduce the risk of new episodes of heavy rains”, stressing that “the work has been complex due to the variety of damage and the large number of sections affected”.
One million for sanitation
According to what they have added, Abaqua has carried out very extensive actions to recover the operability of all the sanitation and purification facilities of the municipality of Ibiza, which suffered direct damage due to the entry of water and sediments.
The most affected point was the Port pumping station. The flooding of the electrical rooms completely disabled the sewage and rainwater pumps.
In order to keep the system operational, a temporary generator set was installed, new control panels were installed, transformers were replaced, frequency variators were renewed, and damaged sensors and electronic equipment were replaced. The accumulation of sediment required manual intervention in the wells and the removal of large volumes of material.
The pumping stations of the Cero, Jesús and Talamanca collectors were also inoperative to varying degrees. At these points, sand removal, pump repairs, chamber cleaning and replacement of equipment damaged by the water ingress were carried out.
At the Ibiza treatment plant, work was carried out on the recirculation systems, dehydration equipment and flow meters affected by the flooding.
The manager of Abaqua, Emeterio Moles, explained that “the sanitation system of Vila suffered very significant damage in a matter of hours, and it has been necessary to act simultaneously at numerous points to ensure the basic operation of the network”. Moles emphasized that “the coordination between administrations and the work of the technical staff have been decisive to avoid major problems”.
The dana also damaged one of the strategic elements of the upstream supply. The flow of the Santa Eulària river displaced about 25 meters of the East branch pipeline, tearing off part of the concrete protection and leaving the pipe suspended at several points.
The repair required opening a new access for machinery through agricultural terraces, removing the damaged sections, reconstructing the eroded bed with concrete and gravel and installing new sections of ductile iron pipe with reinforced anchors. During the most critical days it was necessary to carry out extraordinary supply maneuvers from the Sant Antoni and Ibiza desalination plants to compensate for the deficit generated by the failure.
