The Elorrieta pump

Part of the facilities of the old Bilbao sewage system can be seen in the Karmelo Larrea Park in the Elorrieta – San Ignacio neighbourhood. Designed by the engineer, Recaredo de Uhago in 1894, it was the first modern wastewater purification system in the whole of Spain; it included a separation mesh, a large tank and a steam engine room with Worthington pumps which are still preserved. In 2022, it was declared a Monument Cultural Asset for its historical value.
