The water resulting from the decomposition of the waste deposited in the landfills operated by the EGF goes through a rigid and efficient system of Treatment of Leaching Water, guaranteeing a strict environmental protection system.

In some units, such as in Algar, the treated water is still used inside the business itself, as in the washing of vehicles and floors of the unit.

Still, Valorsu's work with the Hydrographic Institute to monitor the quality of water and sediment should be highlighted.

In this case, the monitoring involves several aspects, from the evaluation of the impact of the Cooling Water Circuit (CAR) to the quality of the water and the sediments.
