MCRC has developed a simple, cost-effective biological water purification system that provides clean, safe drinking water to rural communities. This innovative design uses a layered filtration system, where river sand and pebbles are packed inside a durable PVC pipe, with an additional carbon cartridge attached to the main column. Together, these layers filter out contaminants, removing up to 98.9% of coli form bacteria and effectively transforming contaminated water into potable water. This system has proven especially beneficial for rural and tribal villages where access to clean water is often limited. Beneficiaries report improved health outcomes and reduced medical expenses, as the water filter significantly reduces exposure to waterborne illnesses. Schools equipped with the MCRC water filters have also seen a positive impact, with children now having reliable access to clean water, reducing sickness, and improving school attendance. To ensure the longevity and effectiveness of the filter system, MCRC provides training to villagers on basic maintenance techniques and troubleshooting tips. This user-friendly design, combined with practical training, empowers rural households to maintain access to clean water independently.
