Two beaches in the municipality of Sant Josep de sa Talaia have been temporarily closed to bathing following a wastewater discharge into the sea.

Cala Tarida and Caló d’en Serral were closed on Sunday, October 4, with the local authorities advising residents and visitors not to enter the water at either beach until further notice.

The closure comes after a period of heavy rain and concerns about the capacity of local sanitation infrastructure.

Temporary Closure at Two Beaches

The affected beaches are Cala Tarida and Caló d’en Serral, both located on the western coast of Ibiza within the municipality of Sant Josep de sa Talaia.

The town hall has asked swimmers to avoid the water in both locations while the situation is assessed.

No reopening date had been announced in the latest information available.

The authorities have said that further information will be provided once there is an update on the condition of the water and when bathing can safely resume.

Residents Raised Concerns Before the Closure

The closure followed concerns raised by residents of the Cala Tarida area on Saturday, October 3.

The local residents' association had warned that the area's sewage network was struggling to cope and shared images that, according to the residents, showed wastewater reaching the sea.

Those reports preceded the municipal decision to close the two beaches.

However, the precise cause of the discharge should not be assumed from the residents' reports alone. The available information confirms the discharge and the subsequent bathing restriction, but does not establish that a particular infrastructure failure was definitively responsible.

Water Quality Controls

The Balearic Government operates a bathing-water surveillance programme designed to protect public health during the bathing season.

Water samples are analysed for indicators including Escherichia coli and intestinal enterococci.

The 2026 programme establishes specific thresholds for determining whether bathing is permitted, not recommended or prohibited. For example, a result above 2,000 E. coli units per 100 millilitres or above 1,000 intestinal enterococci units per 100 millilitres falls within the programme's criteria for a bathing prohibition.

The programme also takes account of factors including rainfall and sea conditions when monitoring bathing areas.

A Recent Run of Water-Quality Incidents

The latest closure comes after other wastewater-related incidents in Ibiza during the end of the 2026 bathing season.

In Sant Antoni de Portmany, s'Arenal had previously been closed following a wastewater discharge. The beach was subsequently reopened after new analyses confirmed that the water had returned within the required quality limits.

The incidents highlight the importance of continued water-quality monitoring, particularly following heavy rainfall and pressure on sanitation systems.

No Reopening Date Yet

For Cala Tarida and Caló d’en Serral, the latest information does not provide a specific date for reopening.

The beaches will remain closed to bathing until the authorities determine that the water is suitable for swimmers.

Residents and visitors are therefore being asked to respect the temporary restriction and avoid entering the water at the two affected beaches until official confirmation that bathing is permitted again.

Further updates are expected once the relevant checks have been completed.
