Damage from the latest round of storms is estimated at €110 million, while engineers warn that neglected water infrastructure could leave Andalusia more vulnerable to both drought and intense rainfall. The regional government says 92 projects for which the State is responsible remain pending.
The Junta’s September 2026 list covers 11 dams, eight desalination projects and eight wastewater-treatment schemes. It also includes 27 supply projects, 19 involving waterways and flood protection, and 19 for irrigation. Five entries have no publicly listed location.
The regional government identifies Alcolea as its foremost priority. It also wants work to advance on the Gibralmedina dam and San Calixto. Agriculture, Fisheries, Water and Rural Development Minister Ramón Fernández-Pacheco has asked the Ministry for the Ecological Transition and the Demographic Challenge (Miteco) to update prices and allow the Junta to complete the Alcolea project. He says a funding agreement, plan, contract award and environmental-impact declaration are already in place; the works have not been completed.
For Alcolea, Grupo Azvi has proposed a public-private partnership covering the Trigueros Canal, water-treatment facilities and associated infrastructure. The proposal still requires ministerial approval. The Junta says the project could support water supply and help contain flows from the Odiel river, reducing flood risks for Gibraleón and Huelva city.
The other two dams address separate risks. San Calixto is intended to regulate the Genil and reduce flooding in Écija and Palma del Río. Gibralmedina, in Cádiz, is estimated to require nearly €800 million. The Junta also seeks flood-control works on the Antas and Almanzora rivers in Almería, as well as measures in the lower Guadalhorce basin.
Engineers say maintenance is as pressing as new construction. Internal reports from the Directorate-General for Water indicate that half of state-owned dams need urgent work. Alberto Marina, dean of the Andalusian College of Civil Engineers, has also criticised the appointment of people without relevant engineering qualifications to manage some dams, saying the required staffing rules are not being met.
The storm damage adds to a wider repair bill. More than 11,000 people were evacuated during the winter 2026 storms. The Junta announced nearly €294 million for repairs to rural roads and water infrastructure, while the central government had allocated €619 million for reconstruction work on waterways and hydraulic infrastructure, according to figures released by the Guadalquivir River Basin Authority in July.
Other pending schemes concern water supply and treatment. The Junta wants the San Roque and La Línea de la Concepción treatment plants addressed, alongside upgrades to facilities in Málaga and a connection between the Málaga and Costa del Sol systems. It also lists treatment works for La Janda and Barbate, El Rocío and Hinojos, plus an expansion of the Almonte-Rociana plant in Huelva. A previous report on rain warnings in La Palma covered a separate weather episode; the Junta’s list concerns long-term water infrastructure.
For desalination, the Junta is seeking repairs to Carboneras I and a second plant at the same site, as well as expansion of Campo de Dalías I. Its list also includes the Bajo Almanzora II and Costa del Sol Oriental and Occidental plants. Supply projects include the Puente Nuevo-Sierra Boyera connection in Córdoba and the Alcolea-Piedras line in Huelva, alongside networks for the Sierra Norte of Seville and the Cádiz area.
