DWTP of the Consorcio de Aguas Bilbao Bizcaia Biscay (Basque Country), Spain See on Google Maps
The Bilbao Bizkaia Water Consortium awarded ACCIONA the contract to improve the performance of the DWTP, the second most important of all the consortium's water supply facilities, as it supplies the municipalities of Durango, Iurreta, Mañaria Izurza, Elorrio, Zaldibar and Ermua.

The Garaizar DWTP had only one decanter, which prevented important maintenance and conservation work from being carried out properly, since it cannot be taken out of service for more than a few hours. The project has managed to provide it with an additional decanter to increase quality guarantees, in addition to other improvements to leave a completely renovated facility to adequately fulfill its function over the next few years.
