Industrial Control Networks (ICN) in Water Purification Systems: A South African Case Study

Industrial control networks (ICN) have become indispensable to the functionality and reliability of water purification systems globally. These networks represent a transformative shift from manual operations to advanced automation, enabling real-time monitoring, precise control, and improved operational efficiency. As the demand for potable water grows, the need for robust and reliable ICN becomes increasingly critical. This study explores the performance and technology management of ICNs within a major water company in Gauteng, South Africa, which serves both urban and rural populations. The company has experienced significant issues, particularly plant downtimes caused by malfunctions in its industrial control network. A qualitative research methodology addresses these challenges, incorporating primary and secondary data to evaluate the factors contributing to network performance issues. Primary data collection involved a carefully designed questionnaire administered to a sample of technical experts. Secondary data was sourced from the company's internal databases, which offered critical information about existing standards and technical specifications.
