Arriaran Reservoir

The Arriaran Reservoir is a water storage structure in the Basque region that extends approximately 200 meters and rises about 57 meters high. It collects and holds water that supplies fresh water to populations in the surrounding areas.

The structure was built in 1993 and represented an important step forward in water management for the Basque region. It became part of a broader development of regional infrastructure at that time.

The reservoir supplies drinking water to villages in the surrounding area and plays a vital role in the region's daily life. Local communities depend on this structure to meet their water needs throughout the year.

The reservoir sits in a natural landscape and is surrounded by walking paths that let you explore the area. Visitors should know that access may be limited and the best views are often from the shoreline.

The structure works without extra support systems by using only the weight of concrete to hold back water pressure. This simple but effective design approach makes it an interesting example of engineering skill.
