South Africa: Water and Sanitation at the Vaal River Integrated SystemThe Department of Water and Sanitation is continuing its appeal to the people of Gauteng to continue to use water sparingly as dam levels in the Integrated Vaal River System (IVRS) remain in position strong this week.

According to the Department’s weekly reservoir status report, IVRS water storage has decreased slightly from 99.7% last week to 99.5% this week. However, the system is stronger compared to last year at the same time when the system (IVRS) was at 85.6%,

Registering a slight decline, the Vaal Dam fell from 102.1% last week to 101.4% this week. In the comparative period last year, it was 91.4%. .


The Grootdraai Dam, which has increased week by week, has seen a decrease this week. It went from 100.2% last week to 99.9% this week. Last year’s 83.1% levels indicate the dam was lower than current levels.

“We attribute the declines to the winter dry season. However, we hope the system will see an improvement as we say goodbye to this season and look forward to the summer season,” spokesman Sputnik Ratau said.

For the second week in a row, the Sterkfontein dam, which is a reserve dam for the IVRS, is above the 100% mark. Currently it stands at 100.4% while last year in the same week it was below 99.6%. The Sterkfontein dam is one of the critical dams in the system which has held firm over the months.

Ratau reiterated that the noticeable drop should not cause residents to become overly concerned, as most IVRS dams are still above average, even amid the drop in overall storage capacity. water, but there is no time to be complacent. The need to reduce water demand remains.

This week, the Bloemhof dam maintains last week’s level at 106.8%. That’s slightly higher, compared to levels of 106.2% in the same week last year.

Mohale Dam continues to rise as it remains above the neutral 90% mark. Mohale Dam levels have seen a slight improvement from 98.2% last week to 99.2% this week. During the same period last year, the dam stood at 31.9 percent, showing that the dam had been on a steady downward trend.

The Katse dam remains impressive. However, this week it has slightly decreased from 90.5% last week to 90.0% this week. This is higher than the 67.9% recorded in the same period last year.

The Department of Water and Sanitation is pleased that the IVRS, the country’s largest system, has been able to stay positive, while all South Africans need to remember that the country remains water scarce.
