Further, to avoid accidental discharges into natural environments, Bel uses dedicated facilities to protect the path of the water and river-water drainage points adjacent to the sites. Bel ensures that the temperature and the amount of organic matter in the water discharged by the sites comply with all regulations in force, to limit the negative impact on natural environments.
Most of the wastewater is treated internally at the sites. When treated by a third party, Bel pre-treats the water.
Most of the sludge from the Group’s water treatment plants is recycled via the appropriate treatment channel. Some of the sludge enriched with fertilizing elements is spread on farmland.
