Water
Industrial Effluents
Our own wastewater treatment plants (WWTPs), as well as hydrocarbon separators and settling tanks, receive and treat wastewater so that it can be returned to the environment in compliance with legislated quality standards.
In addition to cleaning the infrastructure supporting the treatment of industrial effluents, with environmentally appropriate disposal of oily waters, the wastewater is periodically analyzed by accredited laboratories to assess and ensure the quality of the discharged effluents.
Exterior train washing is preferably carried out at automatic washing gantries, with water recycling and wastewater treatment systems in place.
Telemetry Applied to Water Consumption
Monitoring water consumption using telemetry allows for active detection of water leaks, helps reduce losses of this scarce resource, and enables the identification of anomalies in the supply network for much faster repairs.
In 2025, it stood at 19%.
With regard to the consumption of water from the public supply, researchers found that on 1 January 2025, the frequency with which the various water suppliers took meter readings at different locations had decreased; consequently, the 19% decrease in consumption of water from the public supply, compared with consumption in 2024, may be partially inaccurate. However, it is clear that the decline in water consumption from the public supply has been a consistent trend since 2023, when telemetry began.
