What the Project Is
Submariver® is a proprietary system developed by Via Marina for the transport of substantial quantities of water over long distances. The system is designed to move fresh water extracted at the mouth of a river for urban or coastal agricultural uses, as well as treated wastewater from a large coastal city’s treatment plant for agricultural applications or to recharge underground aquifers near the coast – all while meeting the discharge standards required by the treatment facility. This innovative approach benefits households, agriculture, industry, and even the environment upon delivery, thereby fostering the economic and social development of coastal regions. Quite impressive, right?
Main Benefits of the System
- Transports fresh water for urban and coastal agricultural use and treated wastewater post-standard compliance.
- Delivers substantial water quantities, serving households, industry, and the environment effectively.
- Supports economic and social development in coastal areas by providing a reliable water source.
- Achieves over 1,000 km of transport economically through strategically placed intermediate steps.
- Operates with minimal energy consumption while managing several tens of cubic meters per second.
- Incorporates a pipe with a diameter of up to 4 m, ensuring high-volume water transport.
Installation and Engineering Aspects
The pipe is laid with its ballast from a laying barge and is constantly supplied by support boats, moving at a pace of several kilometers per day. This method eliminates the need for any ground preparation, making the process efficient and straightforward. In cases where the transport distance is very long, the design allows for the installation of offshore platforms or a short coming ashore every 200 or 300 km to restore pressure in the pipe. These steps not only ensure the continuity of water pressure but also can serve as additional water intake or delivery points. A well-thought-out system indeed, with each intermediate installation acting as a vital link in a long chain of infrastructure.
Advanced Materials and Pipe Features
The pipe itself is a marvel of modern engineering. Constructed primarily from high-strength thermoplastic textile fibers, it is exceptionally light and completely flexible. It can compress and then inflate again, ensuring resilience when faced with the dynamic conditions of underwater transport. Special coatings are applied both inside – to guarantee watertightness – and outside – to shield the pipe from marine environmental aggressions. Additionally, the pipe is certified food quality, which underlines its suitability for transporting water designated for urban and agricultural uses. It is a robust, dynamic solution that marries flexibility with durability.
Ballast and Adaptability
Since the system transports fresh water in a salt water environment, the pipe naturally tends to float. To counteract this, ballast is used, not only to keep the pipe anchored against marine currents or swell, but also to maintain it at a specific distance from the seabed. The integration is carefully engineered: the pipe and the ballast are connected via straps. The length of these straps is meticulously calculated to ensure that the pipe adapts gracefully to the contours of the seabed. This design feature guarantees that the system can cope with different underwater topographies without significant performance losses…
System Versatility and Efficiency
This underwater flexible pipe system is not just about moving water; it is about doing so efficiently and effectively, over long distances, while addressing multiple requirements. The ability of the pipe to stretch, compress, and gracefully accommodate its surrounding environment reflects advanced design thinking. Every aspect of the project – from the installation process to material choice – has been optimized to maximize water flow, reduce energy consumption, and ensure that the system remains durable even under the most challenging marine conditions. Such versatility opens new avenues for water transportation where traditional methods might falter.

Broader Implications for Agriculture and Coastal Development
Submariver® represents a paradigm shift in water transport technology. By efficiently delivering fresh water – as well as treated wastewater – over long distances using an underwater flexible pipe, the project not only addresses fundamental water transportation challenges but also propels coastal agricultural regions into a new era of resource management. The system’s adaptability and efficiency serve as an inspiration for developing innovative infrastructure solutions that prioritize sustainability and economic growth while safeguarding natural ecosystems. With its careful design and cutting-edge engineering, this technology is paving the way for smarter, more resilient water management systems that can have a positive, far-reaching impact on both urban and rural communities along the coast… Simply put, it changes the game.
