Areas of Activity: Environmental Quality

Sectors of Operation: Freshwaters, Dammed waters, Dams, Drainage Networks, Storm Tanks, WWTP, DWTP, Water Supply, Irrigation Modernisation



“Adasa’s online water quality analysis products and the automatic alert stations enable the monitoring and diagnosis of incidents, allowing us to know the characteristics and origin of discharges. We have achieved full compliance with the EU Water Framework Directive to successfully improve the river health and ensure the population’s wellbeing.”
Vicente Sancho Tello – Head of the Automatic Water Quality Information System at the Ebro River Basin Authority (Ministry of Agriculture, Food and Environmental Affairs). Spain

Every year, the Ebro River Basin Authority (CHE) implements an action plan to prevent and reduce pollution of surface and groundwater in the Ebro River Basin and to protect the interests of all users - drinking water treatment plants, irrigation communities, industries, fish farms, hydroelectric power stations, wastewater treatment plants… and citizens.

In line with an innovation strategy, the CHE began implementing an automatic water quality monitoring network in 1993. In 2014, over one million events and alarms were registered resulting in the detection of 57 cases of pollution. With early warning contingency planning was improved, the impact of pollution on the environment was minimised and social and economic benefits were guaranteed. These include assuring the quality of supply to drinking water treatment plants and optimal water quality for irrigation, industry, bathing, etc.


· Obtain real time information and historic records to support decision making and the definition of action plans that foster sustainable water use.
· Enable quick action to mitigate pollution events, detecting the origin of uncontrolled spills.
· Provide all users with real time water quality information to help them manage their activities (drinking supply, irrigation and agricultural uses, industrial uses, aquiculture, recreational uses, hydroelectric power stations…).
· Increase the environmental awareness of citizens and industries.
· Complement manual sampling, providing key information related to water quality trends and watercourse profiles.
