This month, a flow meter totalizing the flow entered into the treatment bowls was put into operation. The data recorded daily from this unit are contrasted with the values measured at the exit of the pumping stations and with the flows measured in each fishing plant. This new measurement unit added to the previous ones, allows us to know the volumes that circulate through the collector in each section. In this way, we control the tightness of the pipeline and verify that there are no discharges or income from the industrial effluent collection system.
