Opinion article by Prof Anthony Turton, Centre for Environmental Management, University of the Free State. 


South Africa and Australia, both arid countries with historical ties to the British Empire, face significant water management challenges. Despite common legal and parliamentary systems, the two nations diverge in their approaches to water sector governance, leading to markedly different outcomes in economic prosperity.

In examining the disparities, it becomes evident that contemporary South Africa is grappling with a scenario resembling a failed state, particularly evident in the breakdown of the electricity and water services sector. This raises a fundamental question – why is the South African water sector faltering while its Australian counterpart thrives? 

Why is the South African water sector collapsing?

Addressing the collapse of the South African water sector requires a nuanced understanding rooted in historical context. The origins of the issue can be traced back to the British Empire’s consideration of federalism during the Anglo-Zulu War. While federalism found success in Canada and Australia, it failed to take root in South Africa.

Fast forward to the present, South Africa operates as a unitary state with a centralised water policy and national water law. This uniform approach leaves little room for local variation, resulting in a cookie-cutter model applied nationwide. Despite water being a constitutional right and given that free basic water is guaranteed to all, the sector faces challenges such as high levels of unaccounted-for water, leakages, and poor management. The absence of justiciable water rights and the separation of water from land ownership hinder private sector involvement. Consequently, utilities are reliant on government bailouts, a situation exacerbated by failing water and electricity grids, diminishing the tax base, and escalating unemployment. 

Australia’s flourishing water sector: A model of innovation 

Australia’s federal structure facilitates a diverse array of state policies and laws, promoting adaptability to local conditions. Boasting over 30 distinct water authorities, each tailored to meet local needs, Australia thrives on a justiciable water right system that allows private ownership. Market forces drive water to its most productive use, and investor confidence is a cornerstone in decision-making. 

Australia’s innovative and market-oriented approach has resulted in well-managed utilities with robust balance sheets. The ability to raise capital from the bond market reduces reliance on public funds for bailouts. Groundwater plays a vital role, accounting for around 40% of the total resource, while innovative technologies, such as seawater desalination, are embraced at the utility scale.   

South Africa’s water sector: uninvestable and facing challenges 

Contrastingly, South Africa’s water sector faces challenges. A lack of innovative approaches, coupled with a rigid, cookie-cutter methodology has stifled local imagination. The state’s hostility towards private capital has rendered the water sector generally uninvestable. While some large water boards still maintain strong balance sheets, the growing debt burden from non-payment by municipalities poses a threat. Limited development of groundwater at utility scale, coupled with a reluctance to replicate successful initiatives, further compounds the challenges. Sea water desalination, where it exists, is confined to small package plants in distressed municipalities along the coast, often seen as unsustainable. 

Australia’s innovative solutions: integrating technology and conservation

Australia stands out for its innovative solutions. With a vibrant private sector driving constant technological advancements, groundwater is a key element in most utilities, actively integrated into the grid and accounting for around 40% of the total resource. Building codes align with water conservation, ensuring rainwater harvesting and aquifer recharge are actively pursued at various levels, including suburb and city. The management of sewage, increasingly sophisticated water recovery from waste, and seawater desalination at utility scale funded by private capital showcase Australia’s forward-thinking approach.  

Centralisation versus decentralisation  

In conclusion, the weakness of South Africa’s water sector lies in the highly centralised approach, resulting in ineffective, one-size-fits-all solutions. Local authorities often lack imagination, relying heavily on taxpayers and hindering innovation. Suspicion towards capital and technology further limits the sectors development. In contrast, Australia’s decentralised approach fosters vibrant water utilities capable of attracting both capital and technology. Entrepreneurs’ initiatives in desalination and water recovery programmes inspire investor confidence, leading to capital influx and secure, water-efficient local economies.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
