Desalination plant changes the pattern of water production

In an effort to meet the current and future demand for water resources in the district of Marina Baja and the northern part of Alicante, a desalination plant with a capacity to produce 80 000 m³/day of desalinated water will be constructed.

Given the uncertain rainfall patterns in the area, this two-phase project will guarantee a sufficient, clean water supply for businesses and residents, contributing to the improved health and providing an added boost to socio-economic development in the region, including 13 direct jobs created once the plant is up and running.

Shortages soon a thing of the past

The central goals of the project are to address water needs, ensure availability of quality water, promote the protection and regeneration of the water environment, promote methods that use water efficiently, overcome water shortages that undermine growth in some regions, and adapt the national policy to EU standards, which are designed to increase environmental and economic sustainability.

Disruptions to water resource availability have been the main trigger behind this project which is part of a Spanish plan (A.G.U.A.) to supply water resources in a more sustainable manner: the new technology will partially replace transfers from other river basins and extractions from scarce underground sources. The desalination project will primarily benefit the municipalities of Mutxamel and El Campello and to a lesser extent the municipalities of San Vicente de Raspeig and San Juan de Alicante.

Pipes pumping out greater volumes

The plant will be designed in two phases: the first involving the civil engineering work for the plant, equipping it with five lines (50 000 m³/day); the second constructing three more lines to reach the target capacity of 80 000 m³/day.

The abstraction of seawater, approximately 113 886 m³/day in the first phase and 182 200 m³/day in the second, is by direct intake via a concrete caisson. The abstracted water will be gravity-driven through a pipeline to a covered tank at ground level from which the seawater will be pumped to the desalination plant.

The plant will use reverse osmosis technology and eight treatment lines, including chemical and physical pre-treatment, reverse osmosis and post-treatment. In all, five buildings will be built to house these facilities.
