The zebra mussel (Dreissena polymorpha) is an invasive species that has caused severe environmental and operational challenges in the Ebro River Basin, impacting both water quality and hydraulic infrastructure. Its rapid proliferation has resulted in blockages in pipelines, reservoirs, and irrigation systems, significantly increasing maintenance costs and reducing the efficiency of water distribution. Additionally, the clogging of water treatment facilities and hydropower structures further exacerbates operational inefficiencies, leading to higher energy consumption and financial strain on water management entities.
To mitigate these issues, the project proposes the implementation of a comprehensive control and mitigation system to manage zebra mussel populations in the Ebro River Basin. The approach combines advanced monitoring technologies, targeted eradication strategies, and preventive measures to limit the spread of the species and restore operational efficiency in water infrastructure. By incorporating early detection systems, eco-friendly treatment methods, and reinforced regulatory measures, the project will ensure a sustainable and effective long-term solution.
This initiative is structured under the Volumetric Water Benefit Accounting (VWBA 2.0) methodology, which will allow for the quantification of the project’s positive impact in a measurable, verifiable, and additional manner. The methodology ensures that the reduction in mussel-induced water loss, the improvement in system efficiency, and the decrease in maintenance costs are accurately tracked and validated, reinforcing the project’s scientific and environmental credibility.
Beyond merely controlling zebra mussel populations, this project optimizes water quality, enhances hydraulic infrastructure resilience, and reduces operational costs. The integration of active control methods with long-term prevention strategies ensures a sustainable improvement in water resource management, protecting both the ecological integrity of the Ebro River Basin and the economic stability of the region’s water-dependent sectors.
The proliferation of the zebra mussel in the Ebro River Basin is a major environmental, economic, and operational issue. Its presence significantly disrupts aquatic ecosystems, damages hydraulic infrastructure, and complicates efficient water management.
One of the primary environmental impacts of the zebra mussel is its competition with native species, causing an imbalance in aquatic ecosystems. By attaching in large numbers to submerged surfaces, it consumes high levels of oxygen and filters significant volumes of water, altering nutrient availability and reducing biodiversity in affected water bodies. This directly affects water quality, increasing turbidity and leading to accumulations of decomposing organic matter, which negatively impacts both aquatic life and drinking water treatment processes.
From an infrastructure perspective, the zebra mussel adheres to pipelines, sluice gates, irrigation systems, and hydraulic structures, blocking water flow and reducing the operational efficiency of facilities. This obstruction increases the need for frequent cleaning and specialized maintenance, generating additional costs for public administrations, water management companies, and agricultural and industrial users.
Another factor complicating the management of this invasive species is its rapid spread through ballast water from boats, which facilitates its expansion into new areas. The microscopic larvae of the zebra mussel can easily be transported through water distribution systems, accelerating their spread and making eradication more difficult.
The lack of preventive measures and early monitoring strategies has allowed zebra mussel populations to expand uncontrollably in various parts of the Ebro River Basin. Without effective containment and mitigation actions, the proliferation of this species will continue to increase, leading to even more severe consequences for the region’s ecosystems and hydraulic infrastructure.
The project combines zebra mussel eradication in critical infrastructure with prevention strategies to minimize new infestations through advanced monitoring and control technologies.
1. Reducing Zebra Mussel Populations Through Targeted Removal
To control existing zebra mussel populations, filtration and mechanical extraction systems will be installed at key points in the hydraulic network. These measures will physically remove mussels before they cause significant blockages. Additionally, eco-friendly biocides will be applied selectively, ensuring the elimination of larvae and adult mussels while minimizing impact on aquatic ecosystems.
2. Strengthening Monitoring and Early Detection
A proactive monitoring system will be deployed to detect infestations before they spread. Water quality sensors in reservoirs and pipelines will enable early detection of larvae, while remote sensing and satellite monitoring will help map affected areas. This data-driven approach will allow for quick and effective interventions, reducing the long-term impact of zebra mussels.
3. Preventing Future Infestations Through Regulation and Awareness
To prevent the spread of zebra mussel larvae to new areas, ballast water treatment regulations for boats will be strengthened. Additionally, an education and awareness campaign will inform local communities, boat operators, and industries about best practices to limit unintentional mussel transport.
By integrating removal, monitoring, and prevention, this project offers a sustainable and science-based approach to controlling zebra mussel infestations and protecting water infrastructure.

The execution of this project follows a structured approach to ensure effective and sustainable intervention in controlling the zebra mussel. Each phase is designed to minimize the spread of this invasive species and mitigate its impact on aquatic ecosystems and hydraulic infrastructure.
1. Initial Assessment and Diagnosis
Before implementing any control measures, it is essential to understand the extent of the problem and identify critical areas of infestation.
2. Implementation of Control Measures
Once priority areas are identified, various strategies are executed to reduce the zebra mussel population and prevent further spread.
3. Monitoring and Early Detection
Continuous tracking is key to ensuring the project’s success and preventing future reinfestations.
4. Infrastructure Rehabilitation and Optimization
To ensure the project’s long-term sustainability, improvements are made to the affected hydraulic systems.
The control of the zebra mussel in the Ebro River Basin is a fundamental step in ensuring the availability and quality of water in the region. The combination of corrective actions and prevention strategies will significantly reduce the impact of this invasive species, benefiting both aquatic ecosystems and hydraulic infrastructure.
This comprehensive approach will ensure a more efficient, sustainable, and resilient management of water resources, allowing the Ebro River Basin to remain a vital water supply source for future generations.
