The Water Utilities Corporation (WUC) has dodged questions on the safety of supplies to the greater Gaborone area after reports of pollution emerged in the South African media.

The Ministry of Health is yet to determine the cause and source of the current diarrhoea outbreak which has claimed 17 lives in the last two weeks.
