Abstract: Water scarcity is a significant broad issue, worsened by causes such as climate change, pollution, andrising populations. Traditional water supplies are insufficient to fulfill the demands posed by increasingpopulations, with detriments to well-being and repercussions to economic growth. In response, emergingtechnologies such as Atmospheric or Air Water Generator (AWG) systems have developed to be potentialalternatives. These machines use ambient moisture to generate water that is safe to drink throughcondensation and the process of filtering. However, its efficacy is dependent on factors such as relativehumidity (RH) and temperature.This study provides a detailed overview of the literature on Atmospheric Water Generatortechnology, diving into its operating processes, the impact of various factors on water production, and itsnumerous uses. It also suggests the development of a prototype of Solar Atmospheric Water Generator(SAWG) that utilizes solar energy as a sustainable water substitute. The study used an experimental designmethod to create a prototype that uses solar energy for water production. Data analysis includes analyzingthermostat settings, testing water stability, and taking into consideration environmental implications.The project aims to build the framework for future developments in Atmospheric Water Generatortechnology, with the ultimate goal of providing a long-term solution to worldwide problems on waterscarcity. By delving into the complexities of AtmosphericWater Generator systems and creating aprototype SAWG, this study aims to contribute to the continuing discussion about water sustainability andresilience in the face of changing environmental circumstances.The study includes comprehensive information on atmospheric conditions of Mexico, Pampanga,design parameters, and pilot test results for a solar-powered atmospheric water generator (SAWG). Theseinclude tables with temperature, humidity, and dew point readings, as well as computations fordetermining the dew point temperature and absolute humidity. The design includes air compressors,controls for thermostats, pumps, copper coils, insulating material, filtration, storage tanks, timers, andother components. Over five days of pilot testing, the water production results were consistent. The overview of studies emphasizes the possible use of SAWGs related to the Philippines' highhumidity levels. It acknowledges efficient prototype concepts and continuous water production, butobserves irregular outcomes, possibly related to launching settings. This result underlines the necessity ofexpanding up the prototype, test it in elevated regions, investigate heat exchanger utilization, and ensurepotable water generation.In conclusion, solar atmospheric water producers show considerable potential as a long-term solutionto global water crisis concerns. Continued research and development can improve the efficiency,adaptability, and reliability of SAWGs, making them a vital component of future water resourcemanagement approaches. SAWGs have the ability to offer clean, safe drinking water to underservedpopulations by using renewable energy and complex materials, therefore contributing to a moreenvironmentally friendly and resilient future for everyone.
