The Ministry of the Sea and Water Cycle has completed the full rehabilitation of the drinking water reservoir located in Costa d’en Blanes, within the municipality of Calvià. The project, carried out by the public company ABAQUA, involved an investment of more than 1.4 million euros and forms part of a broader strategy aimed at strengthening and modernising water infrastructure to ensure a reliable water supply across the Balearic Islands.
The Minister for the Sea and Water Cycle, Juan Manuel Lafuente, visited the facility following the completion of the works together with the mayor of Calvià, Juan Antonio Amengual, the Director General of Water Resources, Joan Calafat, and the councillor responsible for the Costa d’en Blanes area, Isabel Bonet. During the visit, the officials emphasised the strategic importance of the reservoir for maintaining a stable drinking water supply in a coastal area that experiences high seasonal demand.

Rehabilitation of the Costa d’en Blanes drinking water reservoir completed with an investment exceeding 1.4 million euros
The intervention has enabled the comprehensive renewal of an infrastructure with a storage capacity of 21,800 cubic meters. The reservoir is divided into two separate compartments, a design that allows maintenance work to be carried out while maintaining continuous service. This operational configuration is essential for ensuring uninterrupted water distribution to the surrounding population.
The construction works included a complete structural rehabilitation of the reservoir. Damaged concrete elements were repaired, and corroded reinforcement structures were treated to restore structural integrity. In addition, certain components were reinforced using carbon fibre systems in order to enhance resistance and durability.
Advanced waterproofing was implemented using sprayed pure polyurea technology, a modern solution designed to ensure long-term watertightness and protection of the infrastructure. The reservoir roof was also upgraded to improve sealing performance and extend the operational lifespan of the facility.
All interventions were executed sequentially by compartments, allowing the reservoir to remain fully operational throughout the construction period. This approach ensured that the drinking water supply for the area was not interrupted during the rehabilitation process.
Safety improvements were also incorporated into the project, including the modernisation of access points and the installation of protective railings to enhance working conditions for maintenance personnel. Additionally, a thorough internal cleaning of the reservoir was carried out to guarantee optimal operational conditions and maintain high water quality standards.
Further works included localised repairs to walls and structural pillars, along with specialised treatments designed to protect reinforcement materials and extend the service life of the installation.
During the visit, Minister Lafuente highlighted that investments of this nature demonstrate the commitment to strengthening preventive maintenance and operational management of hydraulic infrastructure. Strategic planning and continuous modernisation of water facilities contribute to improving supply reliability and supporting municipalities in managing the water cycle.
Calvià’s mayor, Juan Antonio Amengual, underlined the importance of having a fully modernised reservoir to guarantee water supply for residents of Costa d’en Blanes, particularly during summer periods when water demand increases significantly.
Councillor Isabel Bonet also emphasised that the renovation of this key infrastructure enhances supply security for residents throughout the year and represents a significant improvement for the area.
The project was financed through the extraordinary call of the Sustainable Tourism Tax, which allows resources generated by tourism activity to be reinvested in essential infrastructure projects related to the water cycle. Construction works were scheduled during periods of lower demand to minimise any potential impact on water supply services.
