Repsol YPF

Water management

Water is an indispensable natural resource for the existence of life on the planet. At the same time, fresh water, an indispensable human element, is a scarce resource. These circumstances determine the need to develop management that is orientated to rational use and its protection against any contamination process. Water consumption in Repsol YPF activities is mainly produced in refrigeration systems, water production and product purification operations. As a consequence, residual effluents are generated which are treated and later poured into the receiving areas (sea and rivers).

Of the most significant pollutants  it is fit to mention: hydrocarbons, solids in suspension, and chemical oxygen demand. In addition to other less important pollutants generated (ammonia, nitrates, phosphates, phenols, sulphurs and BOD - Biological Oxygen Demand).

In all cases, appropriate management is required to deal with one most significant environmental impacts of the companies activities. The main areas of its management are: 

• Optimise the consumption of water.
• Favour the reuse of purified water. 
• Control, characterise and separate currents
• Reduce spillage          

A special case occurs during oil and gas extraction operations, because they are frequently accompanied by production water, which is once again injected into the deposits, reducing the impact on the discharges to the water
All these commitments are compiled in the company’s corporate regulations regarding water management.
