Hormisoria, the Spanish pilot site of the Rotate Project, was visited by ANEFA together with the UPM team. The El Tomillar gravel pit is located between the administrative concessions of Canredondo de la Sierra and Dombellas, both belonging to the municipality of Garray in the province of Soria, Castilla y León, Spain.
The visit focused on finding a suitable location to install an aquatic sensor in the vicinity of the Duero River, which is adjacent to the exploitation and is cataloged as an SCI (Site of Community Interest) area called Riberas del Río Duero y Afluentes (Banks of the Duero River and Tributaries). This sensor will be fixed in an area of the extraction site where there is good reception and data connection to be able to monitor the analysis remotely, so it won’t be necessary for the technicians to travel to take the measurements each time they need to.
The sensor will allow a physical-chemical analysis of the water quality of the Duero River; various analyses can be performed such as the calculation of temperature, pH, conductivity, turbidity, hardness, or certain more specific parameters such as alkalinity or number of sulfates in water.
Currently, the sensor is in the final laboratory tests to be installed at the specific point decided during the visit, while waiting to determine which physicochemical analysis will be carried out.
