By Testing Wastewater treatment plants coronavirus outbreaks can be found even without testing individuals for Covid-19

I was watching MSNBC last night and one of the way (On the 11th hour) with Brian Williams, you can test the remains of waste in waste treatment plants to find out whether a whole area is having a severe outbreak of covid-19 even without testing individuals for covid-19 because you will find evidence of it in their waste at waste treatment plants. They are doing this already in England and in Delaware in case your city or county wastewater treatment plant  is interested in doing this too.
