Water transportation is the international movement of water over large distances. Methods of transportation fall into three categories:

• Aqueducts, which include pipelines, canals, tunnels and bridges
• Container shipment, which includes transport by tank truck, tank car, and tank ship.
• Towing, where a tugboat is used to pull an iceberg or a large water bag along behind it.

Due to its weight, the transportation of water is very energy-intensive. Unless it has the assistance of gravity, a canal or long-distance pipeline will need pumping stations at regular intervals. In this regard, the lower friction levels of the canal make it a more economical solution than the pipeline. Water transportation is also very common in rivers and oceans.
