“…McBean and Farrow (2021) conducted research focused on enhancing the GWF by evaluating the advantages of a diskshaped configuration (as opposed to the CPFs). This innovative approach was aimed at addressing several challenges, including affordability, sufficient water supply for households, ease of operation and maintenance, durability against breakage, prevention of recontamination, and long-term functionality.…”

“…The system's unique vertical placement of ceramic filters considerably prolongs their lifespan, minimizes clogging, and provides substantial surface area to be available for filtration. Additionally, the inclusion of a large raw water reservoir reduces the necessity for frequent refills, renders the GWF well-suited for production at making the GWF at village-level, thus generating local employment opportunities (McBean and Farrow, 2021).…”

While providing safe water for the rural poor is considered a basic human right, there are numerous issues associated with existing technologies with shortcomings. Performance issues have continued to fail to meet the needs of impoverished families due to issues including high cost, difficulties with performance, and continuing needs for maintenance. These issues have severely interfered the safe water accessibility. Key aspects of the Guelph water filter (GWF) system can avoid/minimize many of these issues. The GWF as described herein enables delivery of low cost, long-term performance at 3 log removal of E. coli and can deliver 1 to 3 L of treated water per hour. The GWF is simple to operate, has an ability to provide sufficient water for a family, maintains longevity of performance, is easy to maintain and has protection against breakage during the cleaning process, is repairable at village level, and operates using a sizable reservoir of water to supply raw water, meaning the technology does not need to be refilled frequently. Hence, the capability of the novel GWF technology is shown to bypass many of the troublesome features of alternative low-tech water treatment technologies. The potential for the GWF to function for 2 days continuously avoids the need for young girls to fetch raw water frequently during a day, thereby enabling them to attend school. Hence, the GWF enhances the potential to result in ‘safe water and full schools’, providing the opportunity for girls to receive education and capture socio-economic benefits for the community.

“…Changes in diet are causing issues in increased water stress and decreased water availability throughout the world. Hence, the importance of supply issues arising from increasing urbanization causing localized levels of water stress, has resulted in changes in water usage: from 400km 3 /year per billion people in 1965, to 600km 3 /year per billion people in 2015 (McBean, 2023b). As a result of population growth with associated diet and energy needs adjustments, the increased challenges to manage water sustainability are apparent and profound.…”

Water sustainability has become one of the most severe issues in the 21st Century due to dramatic urban population growth and climate change. This paper reviews some of the critical key water issues that need to be considered/incorporated in the quest for water sustainability for the upcoming decades. The purpose is to recognize the critical circumstances for maintaining water sustainability and recognize that many regions in the world have passed the ‘tipping point’ of balancing their water sustainability and failing to realize that restoring sustainability will be extremely difficult. From the water quantity perspective, several examples are used to demonstrate situations which, in hindsight, have been initially shown to be effective but highly problematic in the long term. The review considers, amongst others, the 1960s India example shows that an agricultural ‘success’ starting in the 1960s has subsequently become an environmental disaster. Additional issues, including the impacts of dietary adjustments, upstream diversions raising downstream shortfalls, and transfers of water from agriculture to urban areas, are examples that demonstrate that to achieve water sustainability, lessons must be learned from the past, and adaptive measures must be adopted to help humanity avoid adverse and irreversible environmental tragedies. Government authorities can learn from this critical review of some approaches and realize their responsibility to proactively promote better water resource management strategies (domestic and international collaborations) and strictly regulate water use practices to better manage water sustainability.
