We built eight constructed wetlands, with zero liquides discharge in Poiana Florilor district of Piscu Ciolpani, South - Muntenia, Romania, for the evacuation of wastewater. Each is equipped with a device for the evacuation of wastewater purified from the constructed wetland only by forced evaporation, DAUZUC. The water treated by the constructed wetland is discharged to the atmosphere and not on ground, in soil or watercourses. DAUZUC uses only natural processes: capillarity, chimney effect .
