No waste will be disposed of into the river Ibaizabal. After being processed by an effluent treatment plant, they will go into the general sewage system.
Together with other factors related to environmental impact, they will at all times be under the control of the autonomous and local authorities.

The project has a comprehensive and detailed Environmental Impact Study (EIS) of all the effects that the plant's activities may have on the environment. This Study complies fully with the mandatory regulations issued by the European Union. The possible effects analysed by the Study, including the means used to remove these, are as follows:

The Plant has been designed in such a way as to ensure that its physical appearance blends tastefully with its surroundings. The state-of-the-art technology of the Combined Cycle system means that greater energy efficiency is achieved in a more reduced space.
In addition an insulated indoor sub-station is replacing the conventional sub-station that requires great space and illumination and produces permanent background noise. This advanced technology, while involving much higher expenditure, will remove any question of impact on the surroundings. Additionally, there are plans to strategically landscape the entire area around the Plant with hedges that blend in with the surroundings, as well as for repopulating the whole area with trees.

Measurements have already been made at all sensitive points over a 24-hour period. Design will ensure that the present levels and legally established limits are never surpassed..

Residual and surface water will be treated at a water treatment plant to ensure that the small amounts of water returned to the Ibaizabal river are completely harmless. Besides, the Hydrographical Confederation as well as regional and local bodies will continuously monitor the effluent and the volume of water in the Ibaizabal river.
