How can we build a water treatment plant and gain agricultural land?

By building the facility underground. This strategy has made use of the surface soil for growing activities, restoring the contaminated soil, recovering the land’s fertility, neutralising the loss of aquatic life and water eutrophication and, as is fitting, for treating the water from Sabadell’s Animal Protection Association.
