Water scarcity looms as a global challenge, and South Africa having experienced droughts and the very real scenario of Day Zero, is no exception to this challenge. Recognizing the urgency of finding solutions to address this challenge, government and businesses are adopting innovative solutions such as water reuse. With water reuse set to contribute about 7% to Cape Town’s total bulk potable water supply by 2040 as part of Cape Town’s Water Strategy, it’s crucial to delve into the intricacies of this essential practice, the types of water treated for reuse in South Africa, and the cutting-edge technologies employed in the treatment process.
Understanding Water Reuse
Water reuse, also known as water recycling or reclaimed water, involves treating various forms of used water to a level suitable for a specific purpose, other than its original use. Some common goals of water reuse are to conserve water resources, reduce operational costs and financial costs, promote sustainability, and increase business resilience against droughts and insufficient supply from different water sources.
You may be looking at alternative water sources rather than water reuse, you can read more about treating water from alternative water sources here.
Implementing water reuse specific to your needs.
Water reuse finds applications across diverse industries, from manufacturing (recycling water for cooling systems, treating industrial wastewater, or treating process water) and agriculture (treating wastewater for irrigation and landscaping and harvesting rainwater) to hospitality (greywater recycling for toilet flushing, landscaping, or cleaning). By understanding the potential applications of water reuse, stakeholders can optimize their business through tailored water treatment systems becoming more efficient and thus more profitable.

Technologies used for water reuse.
Before we get into the different types of technologies used for water reuse, we must mention the technology your water treatment plant requires, and therefore the treatment methods used are influenced by how the water quality is affected by its initial use. This consideration plays a key role in determining the type of technology integrated into the treatment system. As a result, it impacts both the capital cost of setting up the water treatment plant and the operating costs related to component replacements and regular maintenance.
Now let’s look at some of the most common technologies used to treat water:
Filtration processes remove suspended solids, providing a foundation for subsequent treatment.
Microfiltration, ultrafiltration, nanofiltration and as a last resort reverse osmosis effectively separate impurities, microorganisms, and dissolved substances.
Chlorination, UV irradiation, and ozonation ensure the removal of harmful pathogens, guaranteeing the safety of reclaimed water.
Chemical processes create aggregates that facilitate the removal of suspended particles, colloids, and impurities, refining water quality.
Additional and useful considerations to think about
In selecting a water treatment solution, businesses should also weigh additional considerations crucial to the efficiency and sustainability of their operations:
Alternative Power Supply
Recognizing the importance of uninterrupted operations, power supply alternatives such as solar-powered systems, hybrid systems, or incorporating backup systems such as generators, ensure continuous water treatment even in the face of power outages.
The footprint of the systems
The physical space occupied by water treatment systems is a critical consideration. Skid-mounted or modularized systems, enable businesses to adapt and expand their water treatment infrastructure seamlessly. This forward-thinking approach ensures that as businesses grow, their water treatment systems can evolve to meet increased demands without disrupting existing operations.
Conclusion
Water reuse presents a strategic solution to critical business challenges. Industries can reduce costs associated with freshwater acquisition and wastewater disposal, aligning with sustainability goals, and promoting responsible water management. Additionally, water reuse enhances business resilience by diversifying water sources, ensuring a consistent and reliable supply even in the face of fluctuating conditions.
