Desalination plant in Denia

Construction project for the desalination and complementary works for the Marina Alta. Denia – Alicante

The municipality of Denia is currently supplied by both surface water (36%) and groundwater (64%). The surface catchment is located in the River Racons and the underground resources system is comprised of three hydrogeological units: 08.38 (Plana de Gandía-Denia), 08.39 (Almudaina-Alfaro-Mediodía-Segaría) and 08.47 (Peñón-Montgó-Bernia-Benisa).

Due to the low quality of almost all the water collected, both surface water and groundwater, it must be treated in two existing desalination plants: the Racons plant, with a production capacity of 16,000 m3/day and the Beniadlá plant, with a production of 8,000 m3/day.

The Racons plant treats the water from the river of the same name, together with the water collected in the Miraflor and Racons Calpero wells. The product water obtained is mixed with water from the Setla wells, from

better quality, prior to distribution. The water from the Pinella and Beniadlá wells is treated at the Beniadlá plant, as is the water collected at the Junta de Aguas de Denia, S.A. outlet. (Jadesa from now on), although the latter is treated using a physical-chemical process.

The objective of the action is to generate a new source of water resources to supply the municipality of Denia and other municipalities in the northern sector of the Montgó de La Marina Alta, through the

construction of a desalination plant with a production capacity of 24,000 m3/day in a first phase (projected deficit on the 2014 horizon), which can be increased to 42,000 m3/day in a second phase (projected deficit on the 2024 horizon). The objectives pursued are:

      a) To replace unsustainable farms.

      b) To restore a balanced hydrogeological operating regime.

      c) To improve security of supply.

      d) To meet the natural growth in demand.
