To promote rational and efficient water use at our operations, we have modernized treatment systems and developed projects for water reuse and to identify alternative sources at our units.
Using various technologies, the water reuse projects in place at our facilities have allowed for great savings. In 2013, we reused 24 billion liters of water, enough to supply 11.1% of total demand for freshwater in the period and a city of about 600,000 inhabitants for a year.
Get to know a few of our actions:
We have taken measures to treat water for reuse at several units, in particular at the Duque de Caxias Refinery (Reduc) in Rio de Janeiro, and the Abreu e Lima Refinery (Rnest), in Pernambuco.
One of 2013’s highlights was the commissioning of a reuse system at the Presidente Getúlio Vargas Refinery (Repar) in Paraná, which has capacity to produce up to 240 m³ per hour of desalinated water to be reused for steam, with annual savings of up to 2 million m³ of water.
In addition to the actions taken at our units, we sponsor projects related to water management that aim to ensure universal access to and the sustainable use of water, which is critical to ensure life and human development, both in the countryside and in the cities. These include actions related to conserving and improving water availability in terms of quality and quantity, among which protecting springs and riparian areas and the sustainable use of this resource through the Petrobras Socioenvironmental Program.
An example is the One Land, Two Waters (P1+2) Program, which will receive R$200 million in funding over a 12-month period. In 210 municipalities that experience intense drought periods, 20,000 water catchment and storage systems will be built. The water can later be used in food production, in animal husbandry for subsistence consumption, in solidarity exchanges, and for small scale trade.
