Wastewater from agricultural irrigation has a high nutrient content that seeps into aquifers and can cause problems of contamination of water bodies.
At Sacyr, we have launched a project for the reuse of agricultural drainage water, the Deseacrop project (Desalinated seawater for alternative and sustainable soilless crop production).
Thanks to the development of this European Life project, we have demonstrated that desalinated water is not only be better when mixed with groundwater, but also increases crop yields and crop quality. In addition, as a novelty, we have treated the irrigation drainage water (approximately 30% of the initial irrigation) by reverse osmosis desalination so that it can be reused for irrigation. In addition, drainage treatment at the desalination plant is carried out 100% with photovoltaic solar energy.
