We recognize the importance of properly managing water resources, especially their proper and rational use, as well as the controlled extraction of water from surface and underground sources for the company’s operational processes.
It should be noted that the water resource represents a basic element for the proper development of our processes and activities, especially those processes that require cooling, steam production and washing of impurities.
We manage water resources responsibly and rationally as part of operational controls to reduce effluent generation in our operations.
Likewise, we adopt measures to use water resources sustainably, of which we highlight the following: at the technological level, we modernize our equipment; at Talara, we use water from the sea through our desalination plant; at the operational level, we implement wastewater treatment plants and their reuse; at the user level, we promote the responsible consumption of water resources.
The areas of non-industrial services or management control of each headquarters account for the consumption of their water resources. For this measurement, they use contometers or receipts provided by supplier companies.
During 2022, we extracted a total of 1,585,184.45m3 (1585.18 megaliters) of water, of which 74% comes from the sea. The water extraction is in accordance with the authorized volumes and water rights granted by the competition entity.

In areas with water stress, such as the department of Piura, we supply ourselves with seawater to reduce the pressure of groundwater and surface water. We avoid competing with neighboring populations for the use of water, since they require it for their consumption. In total, during 2022, 1,327,927.90 m3 (1327.97 megaliters) of water were extracted in areas of water stress.
