Maintenance and Conservation


There is a need for the hydraulic heritage to preserve its conditions of use and safety to allow it to be used throughout its useful life by having the least incidences possible and fulfilling current legislation on Safety and Maintenance.

These requirements on functionality and legality make a series of jobs to be undertaken at a field and office level a priority, not only in civil works, but also in mechanical and auxiliary elements in the dam-reservoir group, which allow us to guarantee these demands for use and safety.

Main services

OFITECO is able to completely undertake maintenance and conservation tasks for a dam throughout its useful life, including the following main tasks:

  • Maintenance of the civil work, electromechanical elements, electrical installations and communications
  • Conservation operations
  • Inspection, monitoring and auscultation
  • Operating in normal conditions and special situations

Over the last 20 years we have maintained more than 50 large dams.
