Innovative ways of storing irrigation water underground
That is why the Dutch tomato growers of Prominent, recently opened a new demonstration project that showcases underground water storage.

Underground water storage
The showcase water buffer is a unique demonstration of various techniques for local and regional underground water storage. One example is a system that stores excess rainwater through wells in the water-bearing sand layer, essentially creating a freshwater bubble in saline groundwater. The stored water can be used as irrigation water. This way, the injection and extraction of fresh water remains in balance, resulting in a robust fresh water supply, without the adverse effects of a salty waste stream (caused by reverse osmosis). The costs of desalination can be saved as well. This innovative way of freshwater storage can represent a major contribution to the prevention of freshwater shortages.
Since 2012, tomato grower Prominent has been storing the rainwater collected from four growers underground. This process is now used as a showcase, where all the steps are explained with information signs. In a special reception area, other techniques are demonstrated as well.
