Treatment plants

Extension of WWTP La Antilla

The management of this project (2011-2018) entailed the continuation of the project carried out in the first phase of construction of these facilities between 1991 and 1994.
After these works, the La Antilla Wastewater Treatment Station consisted of a physical-chemical treatment system comprising pretreatment, lamellar decanting and pumping to a transmarine pipeline, with a sludge line based on thickening by gravity and dehydration with a filter band.
After completion of the works, the facilities have been transformed into a modern treatment plant with a capacity to supply water to a population equivalent to 300,000 inhabitants, with integral treatment system where the water line is based on biofiltration technology, and with a sludge line with heated anaerobic digestion with cogeneration.

This work was completed with the following services provided under contract:

  • Supervision of the preparation of the executive project; designs and specifications at detailed engineering level for all disciplines: architecture, structures, treatment processes, civil engineering, and electromechanical equipment.
  • Supervision of project works; construction supervision; supervision of operation tests and capacity tests;
  • Closing activities at the end of construction, verification and reception of the works, payment, preparation of minutes.
