'Everyone in these areas is asked to be alert for symptoms, to get tested immediately if they appear and then isolate until they receive a negative result,' NSW Health said.
'The presence of SARS-CoV-2 in sewage may reflect the presence of known cases of Covid-19 diagnosed in recent weeks in the areas served by this sewage treatment plant.
'However, NSW Health is concerned there could be other active cases in the local community in people who have not been tested and who might incorrectly assume their symptoms are just a cold.'
New South Wales recorded only one new local case of coronavirus on Wednesday.
The case is linked to the Berala cluster in western Sydney and is a close contact of previously reported cases.
Premier Gladys Berejiklian was confident the cluster had been contained, saying: 'We are definitely in the mop-up stage.'
