Aena has awarded a one-month contract to an Ibiza company to carry out an audit and intervention on the hydraulic networks at Ibiza Airport, including its wastewater infrastructure.

The contract was awarded to Gasifred S.L. under the file reference IBZ-112/2026. The procurement record gives an estimated value of €14,900, with the final awarded amount set at €14,827.40 before VAT, equivalent to €17,941.15 including VAT.

Audit and Intervention of the Airport's Water Networks

The official contract title is “Servicio de Auditoría e Intervención en Redes Hidráulicas”, or Service for the Audit and Intervention of Hydraulic Networks.

Aena has confirmed that the contract covers an audit and intervention involving the airport's different hydraulic networks.

However, the publicly available information does not provide enough detail to establish the exact technical work that Gasifred will carry out in each part of the system.

The procurement classification describes the service under the category for operation of a wastewater treatment plant.

Contract Runs for One Month

The service is a short-term contract.

The available procurement information gives the contract a period running from September 4 to October 4, 2026, meaning the work is scheduled to take place over approximately one month.

The procurement record shows a single bid was submitted, with Gasifred S.L. named as the successful company.

Comes Amid the Ibiza Airport Wastewater Controversy

The contract comes while Ibiza Airport's wastewater management remains under investigation following reports of contaminated water in the Torrent de sa Font.

The torrent flows towards es Codolar, within the Parc Natural de ses Salines d'Eivissa i Formentera.

The Balearic Government opened preliminary proceedings in August after authorities received information about a suspected wastewater discharge. SEPRONA, the Guardia Civil's environmental protection unit, was also involved in inspections and sampling.

The administrative investigation remains open.

Aena Has Been Ordered Not to Discharge Into the Torrent

The Balearic Government subsequently imposed precautionary measures preventing Aena from discharging water into the Torrent de sa Font while the investigation continues.

The measures were still in force in early September, and Aena had submitted its own analytical results to the authorities for inclusion in the case file.

The existence of the investigation does not, however, establish that all contamination detected in the area originated at the airport.

Aena has previously said that its treatment plant handles wastewater generated by the airport and has also indicated that contamination in the torrent could potentially have other sources.

Environmental Organisations Raised the Initial Alarm

The current investigation followed complaints from several Ibiza organisations during August.

On August 7, social, environmental and neighbourhood groups publicly alleged that wastewater from the airport treatment plant had reached the Torrent de sa Font. They based their allegations partly on laboratory sampling carried out between June 12 and July 22.

The claims led to greater public scrutiny of the airport's wastewater system and its ability to manage periods of high demand.

Aena Has Previously Acknowledged Pressure During Peak Periods

In response to questions about the situation, Aena has acknowledged that its hydraulic system can experience occasional problems during periods of particularly high demand.

The company has also maintained that its wastewater treatment system is designed to treat water generated by the airport and that treated water can be reused for irrigation.

Those statements remain separate from the Government's investigation into the water found in the Torrent de sa Font.

A Second Major Wastewater Contract Has Also Been Tendered

The audit is not the only recent procurement involving the airport's wastewater infrastructure.

Aena also opened a separate tender for a “Cleaning and Unblocking” service with a €220,000 base value and a potential total of €266,200 including VAT.

That contract covers the emptying of tanks, unblocking and cleaning of pipes and pits, as well as cleaning and maintenance work connected to the airport's wastewater treatment plant.

Unlike the Gasifred audit contract, that larger cleaning and maintenance tender had not yet been awarded at the time of the latest procurement information.

Different Contracts, Different Purposes

The two procurements should not be treated as the same operation.

The €14,827.40 Gasifred award concerns an audit and intervention across the airport's hydraulic networks and is scheduled for one month.

The €220,000 cleaning and unblocking tender is a separate maintenance service covering wastewater, sanitation, tanks, pipes and related installations, with a contract period of up to 12 months.

The public documents therefore show that Aena is commissioning both a short-term hydraulic assessment/intervention and a separate longer-term maintenance service.

Exact Scope of the Audit Has Not Been Published in Detail

Although the contract title clearly identifies an audit and intervention in hydraulic networks, Aena has not publicly explained in detail what faults will be investigated, what individual installations will be inspected or what corrective works may ultimately be carried out under the one-month contract.

That makes it important not to describe the award as proof that the airport treatment plant has been found to be defective or responsible for the reported contamination.

At this stage, it is a commissioned technical service taking place while the wider administrative investigation remains unresolved.

Government Investigation Continues

The investigation into the Torrent de sa Font remains separate from Aena's new contract.

The Balearic authorities are responsible for determining the circumstances surrounding the reported discharge and whether any regulatory action is required. Sampling carried out by different authorities and Aena's own analytical results form part of the ongoing process.

No final finding establishing responsibility for the contamination has been publicly announced.

What the New Audit Means for Ibiza Airport

For Ibiza Airport, the Gasifred contract represents a new technical examination of its hydraulic infrastructure at a particularly sensitive moment.

The airport has faced scrutiny over wastewater management, reported contamination in the Torrent de sa Font and questions about the capacity of its systems during periods of intense summer activity.

The audit is therefore significant, but its results will be crucial. Until the work is completed and the relevant authorities reach their own conclusions, the contract itself should not be interpreted as confirmation that the airport caused the reported environmental contamination.

For now, the confirmed facts are that Aena has awarded Gasifred S.L. a one-month €14,827.40-before-VAT contract to audit and intervene in the airport's hydraulic networks, while the separate Government investigation into the Torrent de sa Font continues.
