WATCH: Vaal Floods | Bloemhof residents still recovering from floods
In April, the Water and Sanitation Department was forced to open sluice gates at both the Vaal and Bloemhof dams to ease pressure after high rainfall.
The Water and Sanitation Department continues to monitor the situation at both dams, as more downpours are expected.
