The care of our rivers begins in thewaste water treatment plants and continues in our laboratory in Majadahonda, where we analyze the water that we return to the rivers. Julio Rodrigo explains what the analysis of treated waste water consists of and why it is so important for the environment.
COMMITED TO SUSTAINABILITY
In 2021, the year of our 170th anniversary, we promoted environmental care from all our activities.

VIGÍA SYSTEM
/Given the evolution of the COVID-19 pandemic, the sampling frequency of wastewater related to SARS-CoV-2 has been reduced. Starting in April, the updating frequency of the presence map will be monthly. However, a small network is maintained that, on a weekly basis, performs these same analysis as an early warning indicator and whose results will continue to be published in the weekly report. The reports that are uploaded to this website will have a curve that only represents these points of the permanent network, so the shape of the curve will vary.
Last update: 7/6/2023
Note: In periods of rain, the results in the wastewater can be affected by the dilution of the waters.
*The map shows a color code quantifying the importance of the presence of SARS-CoV-2 based on: the trend in each municipality / district (ascending, descending ...); the absolute value compared to the historical data for this municipality / district.
By clicking on each municipality / district you will also be able to see:
- Name.
- Date of the last validated analysis.
- Indicator of evolution of the presence of SARS-CoV-2 in wastewater.
- Comparative value of the last data with respect to the previous ones of that same point.
- Classification of the observed trend.
