The Challenge of Water Sustainability
The path towards a more sustainable planet requires a collective effort, and wastewater sanitation emerges as a key aspect. Its correct management not only protects public health, but is also essential to combat the climate emergency. Treating wastewater properly reduces greenhouse gas emissions and prevents the pollution of water resources, an urgent need in Catalonia and other Mediterranean regions.
A Day to Reflect on Sanitation
The United Nations’ observance of World Sanitation Day on 19 November is a reminder of the importance of ensuring universal access to safe drinking water and sanitation. Currently, 3.5 billion people lack adequate sanitation services, a situation exacerbated by conflicts, natural disasters and the climate crisis.
Adaptation to Climate Uncertainty
The impact of the recent DANA in the Mediterranean basin has shown us the need to anticipate increasingly frequent natural phenomena. Aigües de Barcelona is implementing projects that seek to improve sanitation infrastructure, such as the Gavà-Viladecans Comprehensive Management Plan, to deal with floods and other disasters.
Resilient Infrastructure
In addition to improving infrastructure, the company manages several rainwater retention tanks in areas such as Badalona and Gavà, which help control water during episodes of heavy rain, preventing flooding and damage to public roads.
Circular Solutions for a Sustainable Future
Faced with the climate emergency, Aigües de Barcelona is adopting sustainable practices that reduce the environmental impact of sanitation and purification. The transformation of treatment plants into ecofactories is an example of this innovation, where waste is converted into useful resources for agriculture and other sectors.
Renewable Energy and Efficiency
In 2023, the company generated more than 8.9 million kWh of energy from biogas, contributing to the energy sustainability of treatment plants, where almost all the energy used comes from renewable sources.
Regeneration: A Necessary Cycle
Water regeneration is a fundamental step in reducing dependence on traditional water resources. In 2023, Aigües de Barcelona regenerated 57.9 cubic hectometres of water, which is equivalent to the water consumed by one and a half million people for one year.
Collaboration for a Common Future
Aigües de Barcelona is strengthening its collaboration with authorities and other agents in water management. It is working on a metropolitan master plan for reclaimed water to ensure the sustainability of water resources and the resilience of infrastructures.
Boost to Sustainable Events
During major sporting events, such as the America’s Cup, reclaimed water has been used for boat maintenance, thus demonstrating the practical application of sustainable solutions in major events.
Responsible management of sanitation is crucial for the future of the planet. The reuse of treated resources in sewage treatment plants is a necessary strategy to move towards a more sustainable world, and every action in this regard counts.
