The European Investment Bank (EIB) has approved a €175 million loan to support Acosol’s water infrastructure investment programme on Spain’s Costa del Sol. The first tranche of €75 million has already been signed, marking the start of a major initiative to improve drinking water supply, sanitation, and wastewater management across western Andalusia.
The investment will benefit around one million residents across 11 municipalities, with demand rising significantly during the summer tourist season. The project includes upgrading water production and distribution systems, modernizing wastewater treatment facilities, replacing aging sewer collectors, refurbishing more than 30 kilometres of drinking water pipelines, and constructing a new water storage reservoir. It also supports renewable energy generation at the Marbella desalination plant and expands reclaimed water networks to increase water reuse.
The programme is designed to address the severe water stress affecting the Costa del Sol by reducing water losses, improving water efficiency, and strengthening infrastructure resilience against climate change and recurring droughts. These improvements are expected to enhance environmental sustainability while ensuring a more reliable water supply for future generations.
The financing forms part of the EIB Group’s Water Resilience Programme, which aims to strengthen water security, modernize infrastructure, and promote sustainable water management across Europe. The project also supports the European Union’s climate action goals by encouraging efficient resource management and investing in resilient public infrastructure.
Through this funding, the EIB continues to support essential infrastructure projects that improve environmental sustainability and help communities adapt to the growing challenges of climate change.
