Galindo Wastewater Treatment Plant (WWTP)
Date: Tuesday 12 November 2024
Time: 10:00 – 13:00
Construction commenced in 1985, and by 1990, the initial phase was operational, resulting in a remarkable enhancement of the river estuary’s water quality. The implementation of biological treatment in 2001 played a pivotal role in restoring the estuary to a satisfactory ecological state, providing a habitat for a diverse range of fish and bird species.
A vast network of drainage spanning over 165 kilometres was established to collect industrial and domestic wastewater, directing it to the Galindo Wastewater Treatment Plant (WWTP) located in Sestao. This state-of-the-art facility was designed to handle an average daily volume of 350,000 cubic meters of wastewater, generated by over a million residents of Bizkaia. Undoubtedly, this plant serves as the cornerstone of the entire system, ensuring efficient treatment and safeguarding the environment.
Etxebarri Stormwater
Date: Tuesday 12 November 2024
Time: 10:00 – 13:00
The Etxebarri Stormwater Tank serves a crucial role in storing and managing excess unit wastewater during periods of intense rainfall along the Nervión-Ibaizabal Interceptor. By doing so, it effectively alleviates the strain on the interceptor downstream from the tank.
In 2014, the Etxebarri stormwater tank, boasting a capacity of approximately 70,000 cubic meters, became operational. Situated in the Lezama-Legizamon industrial estate, adjacent to the Nervión River, it occupies a meander opposite the Bolueta neighbourhood. Its strategic location and robust infrastructure play a vital role in managing excessive wastewater flow and ensuring effective flood control during heavy rainfall events.
Deusto University Syphon
Date: Tuesday 12 November 2024
Time: 10:00 – 13:00
The Deusto University Syphon, a remarkable infrastructure accomplished through the Integrated Sanitation Plan, serves a significant purpose in the transfer of wastewater across the river estuary en route to the Galindo Wastewater Treatment Plant. Operational since 1997, this monumental project has been seamlessly facilitating the movement of wastewater between the riverbanks.
Comprised of two expansive vertical wells, interconnected beneath the river estuary by a meticulously crafted rock gallery, the syphon operates based on the differential levels of these wells. This ingenious design harnesses the syphon effect, propelling water through the gallery’s pipes. The control building, situated in Deusto, is equipped with cutting-edge electronic and electrical systems to ensure optimal syphon functionality. Additionally, the facility boasts remote control capabilities from the Galindo WWTP.
