The project

Closing the loop of water, nutrient and resource management for irrigation activities

Towards Zero waste

Conquer is a European project co-funded by the LIFE Programme that aims to promote the circular economy by developing a system to reuse contaminated groundwater infiltrated in residential areas, maintaining the necessary nutrients and eliminating salinity, for irrigation purposes in the city of Murcia.

The third part of the EU territory experiences water stress. Water reuse has been evidenced as the most sustainable alternative to the use of freshwater sources in terms of cost and environmental impact. However, wastewater salinity is a challenge in wastewater treatment (WWTP) and reclamation (WRP) plants where collectors receive industrial brines, agricultural runoff waters and/or marine intrusion.

Conquer will demonstrate an innovative water reclamation plant (WRP) to enable contaminated groundwater infiltrated in residential areas reuse by dividing nitrates and salinity and obtaining an effluent rich in nutrients to re-use it for irrigation instead of being discharged them to the environment.
