Construcción de la Presa Terroba, La Rioja, España | ACCIONA
Construction of the Soto Terroba Dam
Overview of the Project
- The Soto Terroba dam, constructed by Acciona Infraestructuras, serves over 4,000 residents in the Leza River basin and supports irrigation across more than 750 hectares.
- This dam has a capacity exceeding 8 billion liters of water, addressing current risks in the area and ensuring water supply for nearby populations.
Technical Aspects
- During construction, a landslide disrupted access to remote villages; Acciona focused on stabilizing slopes and quickly restoring communication routes.
- A novel method was employed involving an asphalt layer on the upstream face of the dam to enhance waterproofing, similar to road construction but adapted for steep gradients.
