Big data can play a significant role in addressing global challenges related to clean water and sanitation, essential for human health and economic growth. By 2030, SDG 6 aims to ensure access to clean water, improved sanitation, and water efficiency. Big data helps by collecting, storing, and analyzing data from sensors, remote sensing, and social media to enhance water resource management and sanitation. For example, in India, real-time water quality monitoring using big data identifies areas needing intervention. Solutions include predictive modeling, community engagement, and optimized water resource management. Future innovations will focus on integrating real-time data and improving infrastructure planning, with an emphasis on ethical data use and cloud security.
