A thorough research was conducted to address water quality concerns in Villaverde, Nueva Vizcaya. The study focused on designing and evaluating the Biochar-Based Water Treatment System. This study was conducted to address the urgent need for the provision of potable water that is free from contaminants, particularly during times of increased turbidity caused by heavy precipitation. The basis of the system is rooted in the use of biochar, which is created particularly from coconut shells. This particular kind of biochar is renowned for its remarkable adsorptive qualities. A treatment system with a 250 mL/minute flow rate was constructed using a systematic design methodology. The efficacy of this system underwent comprehensive testing, including evaluations of both physical characteristics and bacteriological integrity. The findings of the study revealed a statistically significant enhancement in the transparency of water and the reduction of microbiological hazards, particularly when the flow rates were lower. The economic evaluations, including both the breakeven analysis and the Benefit-to-Cost ratio, further substantiated the feasibility of the system. Over 48 months, it is anticipated that the system would recover both its initial setup expenses and ongoing running costs, therefore providing a viable and cost-effective alternative for the community. The results indicate that the Biochar-Based Water Treatment System has the capacity to provide safe drinking water and offers significant economic benefits. This system represents a crucial advancement in the pursuit of sustainable water management in the Villaverde municipality.
