Everyone in South Africa lives downstream from a sewage discharge point into their drinking water supply, which is why the Blue and Green Drop reports are so important, says water specialist Anthony Turton.
The country has a closed-loop system, whereby all drinking water comes from a river or dam, but all sewage and industrial wastewater is returned to the same river but in a different place, explains the professor at the Centre for Environmental Management at the University of the Free State.
