Acciona completes wastewater treatment plant in Elgoibar

The President of the Guipúzcoa Provincial Government, Mr. Joxe Joan González de Txabarri, inaugurated the Apraitz wastewater treatment plant in Elgoibar, which was built by Acciona Water. The plant's processing capacity is 29,894 per day, equivalent to a population of 90,027 people. The plant has two pre-treatment lines with a maximum throughput of 5,623 cubic metres per hour, while the primary treatment has 2 lines with a maximum throughput of 2,038 cubic metres per hour and the storm tank can handle 3,585 cubic metres per hour.

The plant uses a sequencing batch reactor (SBR) biological process, in which specifically-timed phases are combined to make a full process cycle. Wastewater is processed in batches on a continuous basis.
