Canals

Irrigation canals can carry relatively large volumes of water over long distances providing there is a small downward gradient.

While canals have their limitations, in certain applications they may be preferable to buried pipelines. Some advantages of insitu concrete canals are that they (a) require less excavation, (b) are inherently stronger than a plastic pipes, (c) it is simple to let water out to the fields, (d) it is a easy to remove mud and detritus
