Effective wastewater management in India is essential to addressing the growing water crisis. Many urban areas lack proper sewage treatment facilities, leading to untreated wastewater being discharged into rivers and lakes. This results in the contamination of drinking water sources, spreading diseases and endangering aquatic life. Implementing decentralized wastewater treatment plants can improve sanitation and reduce water pollution. The reuse of treated wastewater for irrigation and industrial purposes can help conserve freshwater resources. Government policies, such as the National Mission for Clean Ganga, aim to improve wastewater management in polluted river basins. Advanced technologies, such as IoT-based water monitoring systems, can enhance the efficiency of wastewater treatment. Strengthening regulations on sewage disposal and promoting community participation can lead to cleaner and safer water sources.
