Decentralised water and wastewater systems are being implemented to meet growing demand for municipal services either in combination with centralised systems or as standalone systems. In Australia, there has been increased investment in decentralised water and wastewater systems in response to the capacity constraints of existing centralised systems, an extended period of below average rainfall, uncertainly in traditional water sources due to potential climate change impacts, and the need to reduce the environmental impact of urban development. The implementation of decentralised water systems as a mainstream practice at different development scales is impeded by the knowledge gaps on their actual performance in a range of development types and settings. As the wide-spread uptake of these approaches in modern cities is relatively new compared to centralised approaches, there is limited information available on their planning, design, implementation, reliability and robustness. This paper presents a number of case studies where monitoring studies are under way to validate the performance of decentralised water and wastewater systems. The results from these case studies show the yield and reliability of these decentralised systems, as well as the associated energy demand and ecological footprint. The outputs from these case studies, and other monitoring studies, are important in improving decentralised system design guidelines and developing industry wide management norms for the operation and maintenance of decentralised systems.

The water and wastewater sector is an important lifeline upon which other economic sectors depend. Securing the sector’s critical infrastructure is therefore important for any country’s economy. Like many other nations, South Africa has an overarching national cybersecurity strategy aimed at addressing cyber terrorism, cybercriminal activities, cyber vandalism, and cyber sabotage. The aim of this study is to contextualise the water and wastewater sector’s cybersecurity responsibilities within the national cybersecurity legislative and policy environment. This is achieved by conducting a detailed analysis of the international, national and sector cybersecurity stakeholders; legislation and policies; and challenges pertaining to the protection of the water and wastewater sector. The study found some concerning challenges and improvement gaps regarding the complex manner in which the national government is implementing the cybersecurity strategy. The study also found that, along with the National Cybersecurity Policy Framework (the national cybersecurity strategy of South Africa), the Electronic Communications and Transactions Act, Critical Infrastructure Protection Act, and other supporting legislation and policies make provision for the water and wastewater sector’s computer security incidents response team to be established without the need to propose any new laws or amend existing ones. This is conducive for the immediate development of the sector-specific cybersecurity governance framework and resilience strategy to protect the water and wastewater assets.
