The Department of Water and Sanitation has called on water users in Gauteng to use water responsibly.
In a statement on Wednesday, the department urged water users to be cognisant that the Vaal Dam is responsible for supplying water to households and businesses.
This follows a concern raised by the department over shrinking water levels at the dam, as the country enters the dry winter season.
The weekly report on dam levels issued by the department showed that the Vaal Dam continues to gradually decline week-on-week, raising concerns that it will soon float below the 50% mark, as the country earnestly enters into the dry winter season.
“Of particular concern is that in the same week last year, the dam was floating at 72.2% indicating that the dam has over time been shrinking to lower levels. Presently, the dam sits at 50.6%, down from 51.3% last week,” the department said.
Other dams alongside the Vaal Dam in the Integrated Vaal River System including the Grootdraai and Sterkfontein have similarly seen a decline in levels this week.
Meanwhile, the Grootdraai Dam level decreased from 89.9% last week to 89.0% this week, while during the same period last year it hovered at slightly less, but stable levels of 76.7%.
The Sterkfontein Dam recorded a minor decrease from last week’s 93.5% to 93.4%.
The decrease in critical dams in the Integrated Vaal River System has seen a corresponding but slight decline in its levels, as it dropped from 67.9% last week to 67.7% this week.
