• Abstract:

  Water is an essential natural resource for the life of plants, animals and human beings, and is essential in all ecosystems on planet Earth. However, there is a large part of the world's population that suffers from diseases acquired through water contamination, due to limited access to safe drinking water. Therefore, this research aimed to develop a sustainable prototype for alternative treatment of raw water, applied to areas with inefficient basic sanitation services. Two prototypes were designed and executed, consisting of the following operational and treatment phases: storage of raw water; continuous water flow piping; filters, with sand and gravel filtering media; microbiological disinfection area using ultraviolet radiation through sunlight; storage of treated water. The first prototype (A) had filters where the water flows by descending and ascending flow and the second (B) was designed with an ascending flow. According to the results obtained, Prototype B, being lighter, achieved better structure stability, with no leaks. It was also observed regarding the organoleptic quality of the treated water, that in Prototype B the characteristics of the water were superior to that of Prototype A. Finally, it can be concluded that based on the evaluations carried out, Prototype B was more successful in terms of the structural stability of the system and also regarding better water treatment.
