Downside being if there is higher numbers in the community that are not being detected, and when restrictions do ease, it won't be long before VIC is back at square one.

This seems to indicate that it might show up people recently sick.

Does a positive wastewater test result mean that there is an active case of coronavirus (COVID-19) in a local area?
No. While a positive wastewater test result may be due to a person with coronavirus (COVID-19) being in the early active infectious phase; it could also be because someone is continuing to “shed” the virus after the early infectious period. It can take several weeks for someone to stop shedding the virus. It may also due to a visitor having been in the community.
