In the context of a resurgence of the Covid-19 epidemic, SUEZ is deploying an offer to monitor the presence of SARS-CoV-2 in wastewater networks. Developed by the Group's scientific and technical research teams, this innovative system enables local authorities to better assess the circulation of the virus on their territories and to better anticipate the health measures to implement at the neighborhood level.
This new offer relies on scientific research which has established that the viral load present in wastewater is a relevant and early marker (2 to 3 days) of its circulation in populations. The system warns on the emergence of new outbreaks of contaminations as soon as the contamination phase begins, regardless of the proportion of asymptomatic people, and makes it possible to manage the implementation of reinforced protection measures (screening tests, campaigns for barrier measures including the wearing of masks, etc.), or to limit access to certain sensitive establishments.
Already operational in 15 municipalities in Spain, Covid-19 City Sentinel is currently deployed in France, the United States, India and Chile. This approach complements the national surveillance networks currently being developed, particularly in France with the OBEPINE network in which SUEZ is proud to participate.
