CV and mad panic behaviour

[LP]

Hotel quarantine establishments are presumably connected in to the sewage system?

True, some specific locations are isolated and treated separately, but they know which locations are connected to which plants anyway.

But not all sewerage systems are interconnected, they can't explain how the virus is appearing in widely diverse locations. They believe it is possibly the previously infected having a mild recurrence.

Also, the testing is much finer grained, they are out taking samples from sewerage mains in local streets, not all positive samples are coming from treatment sites at the end of the rainbow. Brisbane's recent positive's initially came from street testing, not from a sewerage plant.

Wear your mask in public to be safe.
