Water and Sanitation on water reservoirs demonstrating minor decline

National water volumes continue to shrink as we grow into Spring season

The Department of Water and Sanitation’s weekly state of water reservoirs demonstrate a minor decline. This week, the overall national storage capacity of the country’s reservoirs is at 91.2%, a tiny reduction from last week’s 91.8%, and a significant improvement from last year’s 80.6%.

The country’s largest Water Supply System, the Integrated Vaal River System (IVRS), consisting of 14 dams across four provinces dipped marginally from 97.4% last week to 96.7% this week. Some of the Water Supply Systems that have declined are: Bloemfontein from 97.1% last week to 96.9% this week, Amathole from 82.5% last week to 81.9%, Butterworth from 99.1% to 98.5%, Both Crocodile East and West experienced a reduction by the tiniest margins from 98.9% to 97.7% and 96.8% to 96.1% respectively.

Continuing with the downward movement in as far as Water Supply Systems are concerned were: Luvuvhu from 100.5% to 100.4%, UMhlathuze from 99.1% to 98.7%, Polokwane from 100.1% to 99.6%, Orange from 97.6% to 96.9% and Umgeni dropped from 97.0% to 96.7%.

On the positive note, the following water supply systems experienced some increments; Algoa Water Supply System with dams supplying water to Nelson Mandela Bay Metro is among the systems that have recorded slight improvement, increasing slightly from 16.3% last week to 17.6% this week. However, the system remains low, and dams are still struggling to recover from the persisting drought in the area. Cape Town also moved up marginally from 83.5% to 84.4%, and Klipplaat is steady and unchanged week on week at 100.0%.

Seven out of nine provinces have experienced reductions in water levels namely, Eastern Cape from 70.5% to 70.2%, Free State from 98.4% to 97.7%, KwaZulu-Natal from 87.9% to 87.4%, Limpopo from 86.9% to 86.5%, Mpumalanga from 93.7% to 93.2%, North West from 78.9% to 78.1% and Northern Cape from 107.2% to 105.6%.

On the improvement segment is Western Cape which increased from 71.4% to 72.5%, while Gauteng remains at the same level with that of last week at 97.2%.

The Gariep, which is South Africa’s largest dam dropped slightly from 96.5% last week and is sitting at 95.5% this week. While Sterkfontein Dam, a reserve dam within IVRS, is at 99.8%, showing a minor decrease from last week’s water level of 100.1%. Vaal Dam has declined from 98.5% to 97.8%.

The Department of Water and Sanitation continues to urge water users to be circumspect in the way they utilise water since we have just entered a new season of Spring which is usually characterized by high temperatures in various parts of the country and may result in an increase of water demand.
