About the entity

ACCIONA
The water business of ACCIONA concentrates on water treatment and reverse osmosis desalination, a technology in which it is the world leader.

ACCIONA has been awarded a contract in a temporary joint venture with Aqlara for the operation, maintenance and conservation of the water catchment, treatment and storage installation at Tudela, Navarra. This drinking water treatment plant (DWTP) will not only provide a service to Tudela but also to the towns of Castejón, Fustiñana, Cabanillas and Fontellas.

The contract, awarded by the Municipal Water Board of Tudela, is initially for four years -with a possible extension of one year- for a sum of €6 million (including the possible contract extension).

The DWTP currently provides a service to more than 46,000 residents and has a design flow of  35,600 m3/day. The water treated in the plant mostly comes from direct catchment from the River Ebro (6,000,000 m3/year) and is complemented by intake from nearby wells (2,000,000 m3/year). To a lesser extent, and where necessary, it is also possible to take water rom the Canal de Lodosa (10,000 m3/year).

The Tudela DWTP has a raw water tank with a capacity of 6,000 m3 and a coagulation-flocculation chamber, three sludge traps, sand filtering systems, filters for sludge dehydration and a treated water tank with a capacity of 19,800 m3.

In line with ACCIONA’s commitment to sustainable development and the transition to a low CO2 economy, through the operation and maintenance contract a number of actions and procedures will be developed with the aim of optimizing the energy consumption of the installations. To achieve this, ACCIONA and its partner will apply a certified energy management system as per the ISO 50001 standard.

ACCIONA has in-depth knowledge of the DWTP in Tudela as it participated in its construction in 1992, and later (in 2008) in the extension of the plant. The company also undertook the operation and maintenance of the plant from 1992 to 2009.
