In many parts of the world, fresh water is a scarce resource. Because there must be enough irrigation water available 24 hours a day. The storage of rainwater, drainage or recirculation is essential for any horticultural production company. It is also important to create a closed loop cultivation system to allow water recirculation. There is a wide variety of water storage methods: deposit, water tank or water silo and underground water storage system.
A deposit can be dug in the required size. This means that it can store a large amount of water, and it is a relatively inexpensive solution. One of the disadvantages is that a deposit requires a lot of space. On the other hand, a water storage tanks is compact and can be installed both indoors and outdoors. Rainwater can also be stored underground, as in an aquifer. The surplus rainwater seeps into the ground and recovers when needed.

When groundwater is recovered, a “freshwater bubble” is created that gradually displaces the existing groundwater. The benefits of underground water storage tanks are: space saving, greater operational reliability, protection against external factors (low temperatures, decreased growth of unwanted microorganisms) and prevention of brine production as a byproduct.
