South Africa is facing increasing water stress due to a variety of factors.

South Africa, like the rest of Africa, is facing increasing water stress due to a variety of factors, including inadequate maintenance and investment in water and sanitation infrastructure, unequal access to water, poor water quality, and increasingly unsustainable water demand. Flooding and drought disasters and disruptions in water and sanitation services have become more frequent in recent years amidst a growing population in a semi-arid country.

In addition to the ongoing load shedding crisis we are facing, South Africa is rapidly approaching a situation where “water shedding” is becoming a tangible issue. Although it hasn’t reached a nationwide scale yet, the occurrence of disruptions in water supply systems due to shortages and a combination of other factors is growing significantly.

This situation is detrimental, not only to South Africa’s developmental goals but also to its socio-economic position within the Southern African development community region and the continent as a whole.

This is according to academics from the University of the Free State (UFS) and the University of Pretoria (UP) who were part of a group of academics and industry experts who did an independent assessment of Operation Vulindlela’s impact on South Africa. Pres Cyril Ramaphosa unveiled Operation Vulindlela – a joint initiative of the Presidency and National Treasury that aims to modernise and transform network industries – in 2020 as the vehicle to “fast-track the delivery of economic reforms”.

Prof Paul Oberholster, Director of the UFS Centre for Environmental Management and an expert in wastewater treatment, and Dr Yolandi Schoeman, his Postdoctoral Fellow, together with Prof Emma Archer, Professor in Geography and Environmental Studies at the University of Pretoria were asked by Rand Merchant Bank (RMB) to focus on water.

Bring about the structural change

RMB states in the report that it commissioned a body of work by academics and industry experts to independently evaluate whether the execution of policy initiatives set out by Operation Vulindlela, would bring about the structural change that is necessary to accelerate SA’s growth and employment. The subsequent parts of this report focus on three of the five network industries identified by Operation Vulindlela – electricity, water and transport (ports and rail).

“It was an honour to have been part of this project with RMB and to unpack and strategically assess the water sector in South Africa. We know that there are plenty of challenges, but there are also remarkable opportunities where we can implement solutions and demonstrate impact, bring about change and work hard in turning the situation around as a joint constructive collaborative approach.

“They are very keen on working with leaders in the water space with qualities of strategic thinking, innovation, collaboration, inclusivity, and a strong commitment to sustainable development. It is an impactful contribution indeed,” says Prof Oberholster.

In their sections of the report, under heading South Africa's Blue Revolution: Investing in a thriving water future South Africa, Prof Oberholster, Dr Schoeman and Prof Archer, focused on five themes, namely Water for planetary health, Water for development, Water for climate, resilience and the environment, Water for cooperation and The Water Decade of Action.

“We were asked to evaluate the viability of what is still left to be done in the water sector in South Africa. We were asked to contribute our thinking to the RMB handbook for the purpose of distribution to corporate and institutional clients. As part of our outcome we provided clear and unbiased direction to RMB’s clients on the joint initiative the likely impact of Operation Vulindlela on economic growth and what still needs to be done to turn the water sector around,” according to Prof Oberholster.

Guidelines to improve the country’s water situation

He says their aim was to give guidelines on how to improve the country’s water situation. He believes the work they have done with this assessment and on other occasions, will help the UFS in its goal to be a university that impactfully supports societal development as set out in Vision 130, which states: Our knowledge will continue to contribute to the development of the Free State, South Africa, and the African continent and to advance global knowledge and understanding.

As clean water and sanitation is Goal 6 of the 17 Sustainable Development Goals (SDGs), it is a further indication of the importance of this research and work.

According to Dr Schoeman, reports like these are important because they help raise awareness of the challenges and opportunities for achieving water security and sustainable development. They identify problems and bottlenecks within the industry, helping to target areas that require immediate attention and action. They provide potential solutions and enable dialogue to the problems identified, giving stakeholders a roadmap for action and providing essential background that can enable investment and further inform investment priorities.

“Such reports help to inform planning and decision-making processes by providing data, evidence, and recommendations based on research and analysis.  They encourage collaboration and coordination among stakeholders by providing a common understanding of the issues and potential solutions.

“They also provide guidance and recommendations for decision-makers to improve water resources management and governance. Water is a vital resource for human health, food security, energy production, environmental protection and more, so it is essential to recognise its worth and incorporate it into planning and policies,” says Dr Schoeman.

Blue Revolution

The academics also talks about the Blue Revolution – essential blue solutions – in supporting Operation Vulindlela which can enable a sustainable future for South Africa's water management system. The Blue Revolution in South Africa, write the academics, refers to a comprehensive strategy and functional implementation for modernising and transforming the country’s water sector. It aims to improve water management practices and enhance the water sector’s overall efficiency, effectiveness, and sustainability in enabling planetary health.

Shack study holds research and social upliftment opportunities

When Prof Basie Verster, retired head of the Department of Quantity Surveying at the University of the Free State (UFS), initiated an alternative form of housing for Johannes - one of his employees - a decision was made to base research on this initiative. This research project in Grasslands, Heidedal focused on the cost and energy efficiency of green and/or sustainable shacks.

Esti Jacobs from the Department of Quantity Surveying, together with an honours student in Quantity Surveying, a master’s student in Architecture, and young professionals at Verster Berry, helped with the project.

The physical goals of the project were to create a structure that is environmentally friendly, and maintains a comfortable interior climate in winter and summer, as well as being cost-effective to erect. The structure also had to be socially acceptable to the family and the community.

“The intention was to make a positive contribution to the community and to initiate social upliftment through this project. Structures such as the ‘green shack’ may serve as an intermediate step to future housing possibilities, since these structures are relatively primitive, but have economic value and could be marketable,” she said.

Esti explains the structure of the building, which consists of gum poles and South African pine bearers, with a timber roof and internal cement block flooring. The building is clad with corrugated iron and has a corrugated iron roof finish. Additional green elements added to the structure were internal Nutec cladding, glasswool insulation in walls, internal gypsum ceiling boards with ‘Think Pink’ insulation, internal dividing wall and door, polystyrene in the floors, and tint on the windows. A small solar panel for limited electricity use (one or two lights and electricity to charge a cellphone) and a Jojo water tank for household consumption by the inhabitants were also installed.

Esti said: “Phase one of the research has been completed. This phase consisted of an investigation into the cost of an alternative form of housing structure (comparing traditional shacks with the planned structure) as well as the construction process of the physical housing structure.

“Phase two of the research, commencing in February 2015, will last for two to three years. This phase will include the installation of temperature and relative humidity logging devices inside the existing traditional shack and the new green shack. The logs will be regularly monitored by the UFS Department of Quantity Surveying and Construction Management.

These data will enable the researchers to measure the differences in comfort levels inside the two different structures. The data, together with other information such as building materials and methods, are then processed by software programs. Through the simulation of different environments, building materials, and alternate forms of energy, software models can be used to come up with conclusions regarding more energy-friendly building materials and methods. This knowledge can be used to improve comfort levels within smaller, low-cost housing units.

The UFS will be working with Prof Jeff Ramsdell of the Appalachian State University in the USA and his team on the second phase of the project.

“This research project is ongoing and will be completed only in a few years’ time,” said Esti.

The results of the research will be published in accredited journals or at international conferences.
