Water reuse

for irrigation

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.

Water reuse is the way to go

Water scarcity is no longer limited to a few regions of Europe, but already a concern across the EU, with one third of the territory experiencing 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 still a challenge in wastewater treatment (WWTP) and reclamation (WRP) plants, where collectors receive industrial brines, agricultural runoff waters and/or marine intrusion.

CONQUER will tackle this situation by developing an innovative solution that will enable water reuse for irrigation, thus promoting circular economy.

An innovative solution to close the loop

Conquer will develop an innovative water reclamation plant (WRP) to enable water reuse by dividing nitrates and salinity and obtaining an effluent rich in nutrients, which will be reused for irrigation instead of being discharged to the environment. Dissolved salts, already separated from the reclaimed water stream, will be concentrated and then transformed to sodium hypochlorite, promoting a cost-effective solution to transform concentrated saline effluents into valuable by-products.

Main outputs and achievements
