This capstone project intended to undertake Solar Disinfection (SODIS) as a water purification method for persons deprived of liberty (PDL) in San Ramon Prison and Penal Farm, Bureau of Corrections. After obtaining baseline data on the quality of water from the source, a subsequent study conducted determined the effectiveness of SODIS. Following a successful outcome of these tests, SODIS was then promoted and applied. Appropriate monitoring and evaluation procedures were thereafter conducted to check compliance by PDL. This study employed a quasi-experimental quantitative research design. There were 46 participating PDL who were 60 years old and above housed at the Senior Citizen Camp. This study was conducted for three (3) months, from September to November 2018. Three sets of analysis were conducted: (1) interpreting results based on Philippine National Standards for Drinking Water of 2017 for total coliform count and heterotrophic plate count (2) comparing results with literature, and (3) interpreting results based on the conceptual framework. In terms of ensuring sustainability of practices, a descriptive rating of 5-point Likert Scale for frequency was used. Statistical tools used in this study included mean and median measurements. This study yielded the following: (1) Coliform presence were in all water sources of PDL before the implementation of SODIS; (2) Coliform bacteria were no longer present in a 500 ml PET plastic water bottle treated with solar disinfection; (3) Regadig compliance of SODIS practices, PDL most frequently practiced and sanitized their PET bottles using detergent and water for 1-2 minutes (Week 1-3) with a mean of 5.0; (4) Most PDL frequently practiced checking of the turbidity of water by looking at the samples for suspended particles (Week 1-3) with a mean of 4.99; (5) Most of them practiced filling, capping, and shaking vigorously the bottle for 30 seconds (Week 1-3) with a mean of 4.98; (5) Most of them practiced placing of the bottles in direct sunlight by laying it on the side and not upright (Week 1-3) with a mean of 4.98' and (6) PDL were also most frequently applying the practice of ensuring 7 hours of exposure to sunlight, (Week 1-3) with a mean of 4.96. The results and analysis of the study showed the feasibility of using Solar Disinfection to purify drinking water at the San Ramon Prison and Penal Farm and thus reduce, and even eliminate the mortality and morbidity rate of PDL attributed to water-borne diseases.
