  Many places do.  You may have seen it discussed recently around the polio cases in NYC and London (iirc on locations).
  It's a really good way to get an overview of what is circulating in the population, without needing personal identifiers or individual collectons, and gives a bit of advance indication, since many diseases begin to show up in wastewater before they appear in drs offices etc where they are documented.
context: That should be standard just as a general public health measure to know what is flowing into the country and not just for covid >
  
  Yeah, it would be a pretty easy way to test for lots of different things at once >
  
  Oh, that's actually a pretty good metric. We should also be testing city wastewater
