The challenge
The Muskiz wastewater treatment plant is one of the oldest in the Basque Country, operational since 1998. The end-user, Consorcio de Aguas Bilbao Bizkaia, required an expansion and renovation of the plant to be able to treat a larger capacity, especially during heavy rainfall, and increase the quality of the effluent water.
The solution
Through our licensee partner ACCIONA AGUA, Nereda technology was chosen as the best match. One of the reasons for choosing Nereda was due to the 24/7 virtual operator, which will allow the plant to be operational at all times. A second important reason was the limited space available for the expansion of the plant, where a Nereda takes up to 75% space less compared to other technologies. This will be the first WWTP in Spain using the sustainable Nereda technology.
The outcome
The new Muskiz plant will be treating the wastewater of 15,350 p.e. and is scheduled to be operational in 2023.
