Eptisa will carry out the Structural Health Monitoring (SHM) System of 30 dams of the Ebro - Pirineos Hydraulic Production Unit for Endesa in Spain

Currently 4,000 manual monitoring points and more than 800 automated sensors are monitored

June 24 2013

Endesa has awarded to Eptisa a new addendum to the project for Auscultation services of dams of the Ebro - Pirineos Hydraulic Production Unit (HPU), which is implemented since January 2010, adding as a novelty integrated management of automated monitoring systems.

The project will be developed between 2013 and 2016 in 30 dams in the operation phase belonging to Alto and Bajo Pallaresa, Alto Ribarroja, Ebro, Garona, Segre and Ter groups, located in the provinces of Lleida, Zaragoza and Girona.

All the dams have different monitoring systems installed and adapted to the characteristics of each one, which allows carrying out the behaviour of all of them according to the schedule agreed with Endesa. Currently 4,000 manual monitoring points (instrumentation and topographic) and more than 800 automated sensors are monitored

Eptisa will carry out different activities, such as maintenance and replacement of all elements that are controlled; geodesies for the control of absolute movements, in magnitude and direction of all prims placed in the faces of the dams and slopes; levelling to control vertical displacements of the different blocks of the dams and slopes; monthly reporting to Endesa, and the installation and control of:

  • Pendulums for the control of normal and tangential deformations in the dam.
  • Relative movements between blocks, in the joints.
  • Telethermometers for the control of temperatures of concrete, water and environment in relation with stresses and deformations.
  • Piezometers for the control of pore pressure and gagers for the filtrations control
  • Rod extensometers for monitoring the behaviour of the concrete-rock union vertically and the rock itself in different depths.
  • Triangulation: control of the pillars which forms the monitoring networks in the geodesies
  • Horizontal control of the expansions or contractions of the anchorage of the concrete block on the rocky massif
