Family-Friendly Hydrological Management is an approach that integrates clean water treatment technologies with the principles of safety, affordability, and sustainability at the household level. The primary goal of this management strategy is to empower families to effectively manage the quality of their water, using simple and efficient technologies such as biosand filters, household-scale membrane filtration, and rainwater harvesting systems. This approach not only proves effective in improving water quality but can also be implemented at low cost with easy maintenance, while fostering family awareness of the importance of sustainable water management practices.
