The project, with a planned investment of €468,875, will expand and modernise the entire infrastructure and adapt the wastewater treatment facilities to the strictest management and purification regulations.

The Balearic Water and Environmental Quality Agency (ABAQUA) has published a tender for the drafting of two essential projects to improve the sanitation system in Portinatx, in the municipality of Sant Joan de Labritja (Ibiza). The scope includes the technical design of the new Portinatx Wastewater Treatment Plant (WWTP) and the replacement and improvement of the marine-terrestrial outfall connected to this facility.

ABAQUA Publishes Tender for the Drafting of Projects for the New WWTP and the Improvement of the Portinatx Outfall

The contract is divided into two lots, with a maximum bidding budget of €468,875 (VAT included):

  • Lot 1: Project for the new Portinatx WWTP, with a maximum amount of €127,500 (excluding VAT).
  • Lot 2: Project for the replacement and improvement of the marine-terrestrial outfall, with a maximum amount of €260,000 (excluding VAT).

The expected execution period is six and a half months for Lot 1 and eight months for Lot 2. Both may be awarded as separate contracts.

According to ABAQUA, this project—initially promoted by the Sant Joan de Labritja Town Council to focus solely on the treatment plant—has now been expanded to also include the marine and terrestrial outfall infrastructure. This broader scope will allow for a complete renewal of the wastewater treatment system, from the arrival of the wastewater to its final discharge into the receiving environment. The aim is to modernise and strengthen the facilities, ensure appropriate treatment of both current and future flows, and guarantee that the return of treated water to the environment complies with the most stringent environmental conditions.

This initiative is supported and backed by the Ministry of the Sea and Water Cycle, which, together with ABAQUA, is driving the modernisation of hydraulic infrastructure in the Balearic Islands to ensure efficient, sustainable, and environmentally respectful management.
