Wastewater Treatment and reuse

Our treatment plants and water quality measurement systems have the latest advances in reducing energy consumption and in environmental sustainability, all with the sole objective of guaranteeing return to the natural environment (sea, reservoir or river) in the desired conditions or for potential reuse, always complying with the applicable environmental legislation and reducing the risk of potential pollutant discharges by means of preventive control tools:

  • Consolidated information systems regarding anomalies and incidents to establish plans for minimizing the risk of discharge, implementing preventive actions that guarantee that the water is in an appropriate state.
  • ISO 14001 and EMAS certified, as tools for continuous improvement.

In addition, Sacyr has emergency plans and protocols in place to react quickly and appropriately in case of discharge or spillage with negative effects on the outside environment.
