This monitoring method is still being developed. We hope wastewater monitoring will help us to detect and track the virus more effectively in the future. Read more about this research programme on the website of the National Institute for Public Health and the Environment (RIVM).
Early indicators
Virus particles in wastewater Utrecht
If you are infected with coronavirus, there are likely to be virus particles in your stool. These are flushed down the toilet and end up in wastewater. By testing samples of wastewater collected at wastewater treatment plants, we can get information about how widespread the virus is in the community. Please note: As of 4 March, more refined data analytics are being used. This leads to different values. To find out more about the information on this page, go to ‘Explanation of the data presented’.
Average number of coronavirus particles per 100,000 inhabitants
331.27
10.33 lessthan the previous valuex100 billion
An average is calculated based on all the wastewater measurements collected in one week. It also takes account of how many inhabitants are served by a specific wastewater treatment plant, and how much of the wastewater flowing to the plant comes from the safety region.
Number of measurements per week
60
30 of the 34 sampling locations reported at least one measurement in the given week.
Sampling locations can report multiple measurements per week. The number of measurements used per location per week can differ because not all measurements are successful.

This graph shows the most recent measured value of the average amount of virus particles per 100,000 residents, per sewage processing facility.
