Road Tunnel Wash Water Treatment
Cleaning water from road tunnel washing consumes as much as 100 liters of fresh water per meter, posing significant environmental and resource challenges. By utilizing Mestraco’s technology, the need for fresh water in tunnel cleaning operations can be significantly reduced, promoting more sustainable practices while maintaining environmental standards.

The Challenge of Managing Wash Water in Road Tunnels
Effective management of wash water in road tunnels presents a significant environmental and operational challenge. As part of routine maintenance, road tunnels are washed to remove dirt, oil, and other debris from their surfaces. This process is critical not only for maintaining the structural integrity of the tunnels but also for ensuring the safety of the motorists.
Typically, about 100 liters of wash water per meter of tunnel is used during these cleaning operations. For example, a 1,000 meter-long tunnel can generate up to 100,000 liters of wash water. Without proper treatment facilities, this substantial volume of contaminated water is often discharged directly into the environment, leading to potential pollution of local waterways and surrounding ecosystems.
The Importance of Wash Water Treatment
The treatment of tunnel wash water is essential to prevent the release of pollutants such as oils, heavy metals, and suspended solids into the environment. These contaminants can have detrimental effects on water quality, aquatic life, and public health. Implementing robust water treatment solutions not only helps in meeting regulatory requirements but also plays a critical role in protecting environmental resources and enhancing sustainability efforts within urban infrastructure.

Mestraco Superclean: A Solution for Tunnel Wash Water
The Mestraco Superclean process offers a revolutionary approach to managing tunnel wash water. Known for its efficiency, the system is designed to handle large volumes of water without the need for filters, making it a fast and low-maintenance solution. By integrating Mestraco Superclean, tunnel operators can effectively treat and recycle the wash water, reducing the environmental impact and conserving water resources.
Mestraco’s technology is particularly advantageous because it is capable of rapidly processing high volumes of water, ensuring that contaminants are removed efficiently before the water is either reused or safely released back into the environment. This system not only meets but exceeds environmental standards, providing a robust solution that supports sustainable practices in tunnel maintenance.
