The airport's goal is to reduce consumption of potable water without reducing the quality of our services.

Until 2012, practically all the water consumed in Malaga-Costa del Sol Airport was collected, treated and supplied from aquifers forming part of its own network of wells, which was registered with the hydrographic agency. The consumption and flow of the wells have been permanently monitored as established in the relevant extraction and consumption permits. It is expected that in the first half of 2013 drinking water will start being supplied by the municipal water company.

Water shortages are a serious problem in the Mediterranean area, and so the aims of the airport's environmental management system include reducing water consumption without reducing the quality of the supply.

As required by the two Environmental Impact Statements for the work to extend the airport, the level and quality of the aquifers are monitored by a network of piezometers.

Drainage for the airport uses a separative system of independent networks collecting rainwater and sewage.

Before being returned to the environment, sewage is treated in two treatment plants, one in the north and the other in the south of the airport, which are authorised by the relevant agencies. The south treatment plant also treats waste water from the aircraft bilges.

To ensure that waters entering the environment are clean, the rainwater network has a series of separators which retain any hydrocarbons the water might have collected. These are five hydrocarbon separation plants and 19 tanks.

Returning waste water and rainwater is monitored regularly at the different points to check compliance with legislation and the parameters set in current permits.
