Frielas wastewater treatment plant belongs to AdTA and is linked to the West edge, Tagus alluvium, and Tagus-Sado basin (left bank) aquifers, affected by the relevant salt intrusion. This wastewater treatment plant discharges treated effluent into the Tagus basin and treats 70 000 m³/day. The discharge of emerging pollutants, expected to increase with population and industrialization rise, has a serious impact on MAR implementation and acceptance.
