The water supplied to the Jatobá and Perimetral offices in Altamira and to the Brasília office is the responsibility of the municipal water supply company, that is, it is supplied by third parties.
Norte Energia estimates the volume of water consumed in these offices based on standard NBR 5626, which defines the requirements for design, operation and maintenance of cold water and hot water building systems.
The supply of groundwater is only carried out at the office on Avenida Tancredo Neves, in Altamira, and its volume was also estimated as recommended by NBR 5626.
Total water withdrawal in all areas, broken down by the following sources:
| 2022 | 2023 | |
| Source | All areas | All areas |
| Surface water | 35.78 ml | 15.59 ML |
| Groundwater | 5.58 ml | |
| Sea water | 0 | |
| Produced water | 0 | |
| Third parties water | 13.89 ml | 8.78 ml |
| Total | 49.67 ml | 29.94 ml |
- Water flow: the ABNT NBR 5626 standard was adopted - Requirements for design, execution, operation and maintenance of cold water and hot water building systems. This ABNT technical standard considers that each person consumes 150 liters of water/day.
- Total number of workers: survey carried out on the number of workers in each Norte Energia office. Perimetral, Tancredo, Jatobá offices and the Brasília office: data was provided by Norte Energia's HR.
For each office, the formula applied considers the total number of workers per month x consumption per person per day (NBR 5626) + 20% (which considers the fluctuation of workers per office). The volume calculated in liters was converted to cubic meters.
Total water collection in all areas separated by the following categories: fresh water and other types of water (total dissolved solids ≤1,000 mg/L)
| 2023 | |
| Source | Water Volume (in Megaliters) |
| Fresh water | 29.94 ml |
| Other types of water (total dissolved solids >1,000 mg/L) | 0 ml |
Water Stress
Water stress is a condition in which the demand for water exceeds the amount available or accessible in a given region or area. This can result from a number of causes, including increased demand due to population growth, industrial activities, intensive agriculture, climate change, poor water management and other human activities.
When there is water stress, resources can become scarce. This can negatively affect the availability of water for human, agricultural, industrial and ecological uses. This can lead to problems such as shortages of drinking water, reduced agricultural production, degradation of aquatic ecosystems, increased conflicts over water use and socioeconomic impacts.
Water stress is a growing global concern, especially in areas where water availability is already limited or decreasing due to factors such as climate change and poor management. Therefore, it is important to implement sustainable water management practices and promote awareness about responsible use to mitigate the impacts of water stress.
The Amazon region is not characterized by an area of water stress, as is the case in the region influenced by the Belo Monte Complex. However, we know how important everyone is in the economy of water use and the role of companies and industries in this scenario. For this reason, we are vigilant and working to reduce our consumption.
