In addition, Domingo Zarzo, founding member of the Water Positive Think Tank, delivered the closing remarks, bringing the event to a close and reinforcing the sector’s commitment to more efficient, collaborative, and regenerative water management.

The modernization of water management services has become one of our top priorities. As demonstrated in our project in Melilla, through a Narrow Band (NB) technology, designed for the communication of Internet of Things devices (IoT), we will be able to digitise the collection of data in the provision of water services in this autonomous city.

The NB-IoT technology will enable us to establish a remote reading and segmentation service that will provide daily consumption information and data on urban water cycles including, among others, reverse flow, or internal leakage alarms.

By implementing this advanced remote reading system, the Melilla’s water system will benefit from a number of advantages. The important amount of automated data available allows an efficient administration and quality of the hydraulic system. This optimized balance between the current resources and the consumers’ demand to reach a more effective use of water, ultimately will result in a more sustainable energy consumption system. Moreover, this advanced technology will ensure the connectivity of elements in complex locations.

With this project, Sacyr Agua promotes the modernization and digitalisation of water services, enhancing a comprehensive remote water meter reading system.

Last Thursday, the event Collaborative Models in Hydraulic Infrastructure Contracts took place, bringing together experts and companies from the sector to analyze new forms of collaboration in the development of water projects.

In this context, Aurora Díaz de Espada, International Operations Director at Sacyr Agua, participated as a speaker in the panel dedicated to the Spanish experience in international hydraulic projects, one of the key sessions of the event.

During the presentation, Aurora introduced the PPP Alliance contract model in Australia, an innovative approach based on close collaboration between the client, contractors, and other project stakeholders. This type of model enables the alignment of incentives, risk sharing, and improved decision-making, ultimately enhancing the efficiency of large-scale water infrastructure projects.

Water availability has emerged as one of the main challenges to sustainable development in northern Chile. In this context, through our Sacyr Agua division, we are strengthening our contribution with innovative solutions that integrate reuse and desalination, moving toward efficient, long-term water resource management.

With a presence in more than 20 countries and approaching our 30th anniversary in Chile, we continue to consolidate our role in the development of strategic infrastructure through our three divisions: Sacyr Concesiones, Sacyr Ingeniería e Infraestructuras, and Sacyr Agua. Our participation in the 21st edition of Exponor reaffirms this commitment, positioning us as a key player in the country’s water security.

Through Sacyr Water, we have built more than 10 plants globally , including the Salar del Carmen Water Reuse Plant in the Antofagasta Region, which we developed in partnership with Econssa. This project, the largest of its kind in Latin America, will treat 900 liters per second of urban wastewater for use in the mining industry, helping to reduce wastewater discharge into the sea and alleviate pressure on aquifers, in line with a circular economy model.

In addition to this achievement , we have been awarded the contract for the country’s first desalination plant for human consumption, located in the Coquimbo Region. The project, with an initial capacity of 800 l/s expandable to 1,200 l/s, will supply more than 513,000 people in La Serena and Coquimbo, in addition to supporting the productive sector, establishing itself as a structural solution to water scarcity.

We continue to promote initiatives that strengthen water security, contribute to productive growth, and improve the quality of life for communities, with a long-term perspective and a focus on sustainability.

The congress covered key topics such as digitalization, sustainability, operational efficiency, water reuse and desalination, as well as climate change adaptation and the development of new technological solutions for water management.

Female Talent

Representing Sacyr, Mercedes Calzada, Patricia Terrero, and Irene Ochoa took part in the event. Their participation highlighted female talent and the growing role of women in the water sector, particularly in technical and innovation-driven fields.

All three professionals actively contributed to the technical program. Mercedes Calzada presented the paper “The Role of WSI in Water Footprint Assessment”, focusing on water stress as a key indicator of the consumption–availability nexus and highlighting the positive impact of desalination on measuring and managing the organization’s water footprint.

Irene Ochoa delivered the presentation “Performance Recovery in Beach Wells Using Sonic Action Combined with Air-Lift Technique”, addressing innovative solutions to improve efficiency in coastal intakes, with a focus on advanced techniques for flow recovery and the optimization of intake infrastructure.

Finally, Patricia Terrero presented “Advanced Quaternary Treatments for the Removal of Emerging Contaminants”, based on the results of the SOS Agua XXI project, which analyzes innovative solutions to improve treated water quality through advanced technologies aimed at the removal of emerging compounds.
