Irrigation water from a water plant will be stored in an underground reservoir, as opposed to a storage tank on the surface. The Dutch group TOM is set to perform the first drill. The drill will take place in Dutch greenhouse area Nieuw Prinsenland. Study by Kiwa Water Research (KWR) showed that the losses will be limited and that the quality remains good. This alternative to buffering is, according to the TOM, preferable to an above-ground storage tank.
The water is produced by an irrigation water plant during the campaign at a local Sugar Factory from September to January. However, the need for irrigation water for greenhouses only occurs in spring and summer. The first hole has a storage capacity of 20,000 m3 of irrigation water, which can be recovered from April 2014. If after two years the buffer is functioning properly, there will be more holes to increase the storage capacity. The research is funded by the TKI-water technology program.
