Nelson Mandela Bay residents have been urged to boil tap water before drinking.
The Metro says this is due to additional water that has been introduced into the water reticulation system through boreholes, to supplement the water supply.
With the addition of unblended ground water into our reticulation system, low dam levels and fluctuating reservoir levels the quality of the water is constantly changing and can not be 100 per cent guaranteed.
Through a system of blending water from different water sources, a blending ratio is used to meet SANS241: 2015 water quality standards.
Currently due to the decline of the water supply sources such as the Churchill Dam, which has dropped below abstraction rates, resulting in the blending ratio not being met and therefore the water needs to be boiled as a precautionary act.
