ABSTRACT
Reagritech has been a demonstration project with the main objective to reduce the consumption of water resources and improve its quality, integrating natural systems for wastewater treatment controlling nutrient and pesticides in the generation source. The main aim of Reagritech Project was to demonstrate a sustainable method for water reuse of agricultural runoff, in order to optimize it, at parcel scale and minimize diffuse pollution. The removal rates attained with cork system convert cork pilot plant into a promising system to be used for the specific removal of nitrate from agriculture polluted waters. Constructed wetlands (CW) and strips of vegetation are natural and appropriate technologies that provide an effective mean of purifying water polluted by nitrates, and therefore, treating diffuse pollution produced by farming practices. Once the potential capacity to pollute is reduced by the CWs, water can be reused for irrigation or other productive activities.
