A new reservoir will soon be added to Glen Marais’ arsenal of infrastructure.
At 60m in diametre, this concrete monster on Dann Road will hold up to 25 million litres of water, supplied by Rand Water.
Commuters using this busy road would have seen its construction commence in April last year.
Once its construction is completed, this mixture of broken stone, cement and water will hold the contents of up to 10 Olympic-sized swimming pools.
According to ward councillor Jaco Terblanche, this water will be distributed to Aston Manor, Nimrod Park, Pomona, Bredell and Glen Marais extensions.
He added that this reservoir is a necessity in the community, as it will address many water-related issues.
“The reservoir will ensure that quality water pressure can be provided to current and future developments. It will also ensure that every mentioned area has running water in the future. Lastly, it will address the water problems these areas had to deal with the past three years.”
Households can look forward to water supplies from this reservoir as soon as July 5, when construction is set to be completed.
Although the building of the reservoir started last year April, resident engineer Phillip Olivier said a lot of diligent planning went into such a structure. “It took up to 18 months to plan and prepare.”
As soon as this planning was done, the about 41 workers did not waste time to create their concrete masterpiece.
In no time, they had dug a metre and a half into the ground, in which the foundation for the reservoir was built. Thereafter, with the help of one excavator, two tipper-trucks and one crane, 35cm thick concrete walls were built and left to dry for 28 days. Once dried, 25km-long cables were wrapped around the walls like an elastic band. This procedure, called post-tension, enables the walls to contain such a large amount of water.
The structure boasts 64 concrete columns, which support a roof that contains 140 tons of steel. One-thousand-five-hundred cubic metres of concrete was used to build the roof.
At about R1 500 per cubic metre of concrete and R1 400 per ton of steel, it will cost R2-million for the roof alone.
However, that may seem like a drop in the bucket, as a budget of R42-million is available for the construction of the reservoir. However, it is estimated that only R36-million will be used.
Once completed, the concrete creation will be sterilised and tested for household use.
Express was escorted to the top of this enormous structure. Here, once the fear of heights had faded, a view that stretched for kilometres was enjoyed.
