📋 Tender Overview

This work is carried out within the scope of the consulting service commissioned by the Directorate of Planning and Development of Water Resources of the ANA.
Those responsible for the preparation of the study explained that the conditions in which the dam is currently being operated are not adequate, that there are electromechanical elements of the discharge pipe in a state of critical deterioration, with a very high risk of failure, compromising not only the operation of the dam and the demand service, but also the but something much more important: the security of the infrastructure itself.
