The European project ROEM+, which has allowed the exhaustive monitoring of the waters of the reservoir Cuerda del Pozo (Soria) to control the eutrophication processes that cause the rapid development of certain algae, has been awarded as one of the Best Life Projects concluded between 2016 and 2017, an award that aims to disseminate the fact that the large-scale application of the innovative solution created has clear environmental benefits.
Eutrophication is a process derived from the excessive concentration of nutrients in the water, especially phosphorus and nitrogen, which promotes the proliferation of certain types of algae capable of harming aquatic ecosystems. It is caused by pollution and affects a large part of Europe’s water resources.
For this reason, the Confederación Hidrográfica del Duero, a body attached to the Ministry of the Environment (MAPAMA), provided institutional and financial support to the company ECOHYDROS S.L. for the implementation of a continuous measurement platform in the reservoir and information management and alert generation, combining sensor networks and predictive simulation techniques.
The system, which has also been coordinated by the Instituto Tecnológico de Galicia (ITG), has been tested on the basin of the reservoir of Cuerda del Pozo (Soria), which constitutes a scenario of study of great interest own Mediterranean rural territories, in the head of the Duero basin, one of the three major rivers of the Iberian Peninsula, subject to various uses such as irrigation, supply, recreational and livestock, among others.
Platforms and two buoys
Thus, a monitoring network has been set up in the reservoir, consisting not only of the main platform anchored in the vicinity of the wall, but also of two buoys in the main tributaries and a mobile platform, which facilitate the detection of algae proliferation.
In this way, it is possible to manage the phenomenon in real time in order to take the necessary measures to guarantee the safe use of water by the population.
The methodology applied in Cuerda del Pozo has been completed with other actions, including detailed monitoring of the data obtained, corrective measures and awareness-raising campaigns among users to warn of the possible effects of water eutrophication.
However, it should be noted that during the years of the LIFE project, the CHD has seen the improvement in the trophic state of this reservoir (248 cubic hectometres capacity), mainly to the implementation of wastewater treatment systems in localities in the area of the High Duero.
