Waste water treatment: India’s sewage treatment landscape

India’s sewage treatment landscape is evolving rapidly, with over 72,000 million litres of wastewater generated daily from homes, industries, and institutions. Treating this volume effectively is vital to prevent pollution of rivers, where untreated discharge causes ecological damage costing ₹50,000 crore annually in health and environmental remediation. Sewage treatment technologies range from simple, low-cost options to advanced systems that ensure high-quality effluent for reuse ... Wastewater treatment is the process of converting wastewater — water that is no longer needed or is no longer suitable for use — into bilge water that can be discharged back into the environment. Wastewater can emanate from several activities including bathing, washing, using the toilet, and rainwater runoff. What Are Waste Water Treatment Systems? Waste water treatment systems are engineered solutions designed to remove contaminants from wastewater before it’s discharged back into the environment or reused.
