Even though the decrease in the Integrated Vaal River System (IVRS) dam levels is marginal – a 0.3% drop from last week and an 23.6% increase from the preceding year – the Department of Water and Sanitation urged residents to use water sparingly.

Gauteng Dam levels overview

Use water sparingly

The Department calls on residents to refrain from flushing toilets “unless it is necessary to do so”, adding that this one small step “could assist to save many litres of water”.

“In the same vein, the department wishes to reiterate that when washing cars water users must refrain from using hosepipes but rather use buckets. This is especially the case for businesses such as car washes”.

Gauteng residents, shockingly, use about 305 litres per person per day, the highest in the country. Other ways to save water includes re-using grey water from washing machine to flush toilets, water the garden, wash vehicles, and so forth.

In addition, residents should keep showers as short as poosible and close faucets when brushing teeth, when doing the dishes, washing hands, etc. You could also bath with less water, or use the Bucket Bath method.

Integrated Vaal River System report

This week’s report shows that nine dams within the Integrated Vaal River System (IVRS) decreased in levels, while four have remained unchanged. An increase was recorded in only dam.

The Department of Water and Sanitation confirmed on Wednesday 19 May that the system is at 91% this week – a drop of 0.3% from last week’s 91.3%. It’s still better than the same period in 2020, when the level was at 67.4%.

“Inevitably, the mixed picture in the levels of the system spilt over to the overall level of system as shown in its decline this week. […] The level of the system this week represents a substantial improvement from 67.4% over the same week in the preceding year”.

IVRS the ‘backbone’ of the continent

The department explains that the IVRS system “is the backbone of the economy of Gauteng as the economic hub not only in South Africa, but the entire African continent”.

“Leading industries that breathe life into the country’s economy, such as Sasol and Eskom, are supplied with water from the system”.

The Vaal Dam dropped from 101.4% last week to 100.7% this week; still a remarkable increase from the 2020 levels at 50%. Furthermore,t he Grootdraai Dam dropped from 94.9% to 93.5%, compared to 89.2% in 2020.
