€23.4 M contract for extension to Melilla desalination plant and operation during construction period

The Executive Board of the Confederación Hidrográfica del Guadalquivir (Guadalquivir River Basin Management Authority - CHG) has successfully unblocked the project to upgrade the plant, for which three different design plans have been drafted since 2015. The new project integrates the previous design plans, which have already received environmental authorisation, and also includes plant operation during the upgrading work, in order to guarantee supply.

The Confederación Hidrográfica del Guadalquivir (CHG), which operates under the auspices of the Spanish Ministry for Ecological Transition, has opened a tender procedure for the extension to the Seawater Desalination Plant of the Autonomous City of Melilla and the operation of the plant during the construction work and the commissioning of the facility. The contract is worth a total of €23,410,534.80.

The current CHG Executive has succeeded in unblocking the project to upgrade the plant, for which three different design plans have been drafted since 2015. Although the three plans received environmental authorisation, none guaranteed the operation of the plant to ensure the supply of water to the city of Melilla while the construction work associated with the extension was being carried out.

For this purpose, a new design plan was drawn up. This plan integrates the previous design plans, which have already received environmental authorisation, and also includes operation of the desalination plant during the upgrading work.

Amongst other enhancements, the extension to the Melilla desalination plant will increase the production capacity of the facility to 30,000 m³/day. This will ensure the supply of quality water in sufficient quantities, thus putting an end to the supply cuts experienced in recent years. In addition, filtration capacity will be increased and protection against severe tidal conditions will be improved. The plant will be equipped with a second filtered water tank and a second seawater intake to facilitate maintenance operations. Energy consumption will also be reduced through the implementation of more efficient systems.

The contract has a total duration of 27months, 24 months for construction work and three months for the commissioning of the extension. The project will be jointly funded by the ERDF and the CHG.
