Gauteng Climate Change Indaba 2019 

Water Wise was invited to exhibit at the Gauteng Climate Change Indaba on 22 November held at Velmore Hotel and Conference Centre, Pretoria. The Indaba addressed issues surrounding climate change and how that can be mitigated with innovative strategies. One of the areas of interest was the incorporation of green buildings in and around our cities and importantly the climate change awareness programmes that will be implemented in the near future. Water Wise's recycled products (see images below) that were on display, spoke vastly on the recycling of waste in an attempt to improve the environment. The products on display were hand-made by one of our community groups from Phaake to raise funds for their organisation and help reduce waste. Delegates had an opportunity to interact with our Water Wise team to learn more about how they can reuse their waste.

Farewell and Goodbye

On 26 November 2019, Water Wise had to bid farewell to their Coordinator, Meagan Donnelly. This was a bitter sweet experience for the team, as one of their own embarked on a new journey. Meagan is a great leader, who amongst other amazing things helped shape the future of Water Wise. She has touched so many people with her selfless efforts of assisting and bringing about change in the water sector. Meagan, as you turn the page in your life's story, we as Water Wise join together in wishing you every success in all your future endeavors!

Interesting Facts 

Why is the Vaal Dam not filling up after the heavy rain? 

In December 2019, parts of South Africa experienced heavy rainfall which resulted into floods that were viewed as a relief to our water crisis. A reading conducted during this time indicated that the Vaal Dam level was at 39.5% in comparison to 78.5% in 2018. In contrast, the Roodeplaat Dam in Pretoria was overflowing during the floods. After these revelations, more questions or concerns were brought to light by the public in an attempt to comprehend the factors that influence dam levels. Below are answers to the frequently asked questions about the effect of rainfall on dam levels.

rainfall-level-protec-arisawa

1. Volume:

In order for dam levels to increase, the volume of rain needs to be high i.e. something similar to thunderstorms or prolonged heavy rainfall. The first rainfall most often just soaks into the ground and fills depressions, like farms dams before it runs off to our rivers and dams. Continuous rain over a long period of time or thunderstorms, both at high volumes, needs to occur to affect dam levels.

2. When:

It takes about three days for the run-off from rainfall (as described below) to reach the Vaal Dam, so there is often no immediate or obvious change in dam levels after rains. In heavily built up and urban areas with little permeable surfaces, rain run-off will be a lot faster than in more natural and undeveloped areas, where water is allowed to permeate into the ground.

3. Where:

The filling of dams depends on where the rains fall. None of the rain we have had in Gauteng goes to the Vaal Dam, so there will be no immediate change in the level of the dam. The water flows either towards the Crocodile and Jukskei Rivers or it joins the Vaal River downstream from the Vaal Dam and goes towards Bloemhof Dam.

4. Vaal Dam catchment:

The Vaal Dam catchment includes the western parts of Mpumalanga (Standerton, Ermelo, Secunda) and the eastern parts of Free State (Villers, Harrismith, Bethlehem, Frankfort). The Grootdraai Dam at Standerton also needs to fill as it is upstream of the Vaal River.
