The number of sites under wastewater testing surveillance for Covid-19 is set to double by next year, said the National Environment Agency (NEA).
Currently, more than 200 sites - including workers dormitories, hostels, nursing homes and residential areas - are under surveillance, with 2,500 samples processed a week.
The frequency of sample collection varies from site to site and depends on the purpose of the surveillance programme, NEA said on Wednesday.
