KWR has been carrying out research for almost ten years into substances in urban sewage water, such as drugs, and coronavirus is also found in stools, so their microbiologists suspected that they could also find the coronavirus SARS-CoV-2 from the stools of infected people in sewage water. In the past weeks, KWR's microbiologists conducted several investigations at various sewage treatment plants in the Netherlands not because they think that the virus is likely to spread via water, but mainly because KWR could get an indication of the number of virus infections in the population of a city by monitoring the levels of the virus in sewage water.
