Benidorm secures major water lifeline amid climate threat

Benidorm is taking a major step towards safeguarding its future, securing European funding for an ambitious project designed to protect its water supply against the growing threat of climate change. Partnering with Veolia, the city is positioning itself at the forefront of sustainable water management in Europe.

The initiative forms part of the CAESAR project (Climate Adaptation and Economic Solutions for Adaptive Resilience), backed by the Horizon Europe programme. With a total budget of €3 million and a planned duration of three years, the project brings together more than 20 organisations across the continent to tackle climate-related challenges through innovation and collaboration.

For Benidorm, the stakes are particularly high. Its Mediterranean climate already exposes the city to water scarcity, rising temperatures and prolonged droughts—pressures intensified by a tourism model that can see the population surge from around 70,000 residents to nearly 400,000 during peak periods.

A smarter approach to water resilience

At the core of the project is a plan to transform how the city sources and manages water. Rather than relying heavily on traditional supply systems, Benidorm is investing in advanced reclaimed water infrastructure to diversify its resources.

This approach focuses on reusing treated water to reduce dependence on natural reserves, ensuring a steady and high-quality supply even during dry periods. By strengthening its water cycle, the city aims to significantly lower its vulnerability to drought and climate-related disruptions.

The strategy reflects a broader shift in how cities are responding to environmental challenges—moving away from reactive solutions towards long-term resilience planning. In Benidorm’s case, this means combining cutting-edge technology with sustainable practices to future-proof one of its most essential resources.

Unlocking investment through innovation

Beyond infrastructure, the CAESAR project also introduces a new financial model designed to attract private investment into climate adaptation. One of its key objectives is to demonstrate that sustainability projects can be both environmentally necessary and economically viable.

Officials estimate that this model could mobilise up to €7.2 million in private funding for water infrastructure in Benidorm alone.

By bridging the gap between public funding and private capital, the initiative aims to accelerate the rollout of critical projects while reducing the financial burden on local authorities. This public-private partnership model is increasingly seen as essential in addressing the scale of investment required to combat climate change.

A blueprint for other cities

Benidorm’s role in the project goes beyond local impact. The city has been selected as a key case study and will act as a demonstration site for other European destinations facing similar environmental pressures.

The technologies and financial frameworks developed here are intended to be scalable and replicable, offering a roadmap for coastal and tourism-driven cities across the Mediterranean.

In addition, the project will host “Climate Resilience Dialogues,” bringing together governments, businesses and communities to rethink how risks and responsibilities are shared. This collaborative approach is designed to create more inclusive and effective solutions to climate challenges.

Leading the way in sustainable tourism

For a city globally known for its tourism industry, the project reinforces Benidorm’s commitment to sustainability. Ensuring a reliable water supply is not just an environmental priority—it is also critical to maintaining its economic model and quality of life.

By embracing innovation and collaboration, Benidorm is turning a pressing challenge into an opportunity for leadership. As climate change continues to reshape the future of cities worldwide, initiatives like this highlight how forward-thinking strategies can protect resources, attract investment and inspire change far beyond local borders.
