India’s Urban Wastewater Crisis and Solutions

India faces challenges regarding urban wastewater management, with only 28% of urban wastewater being treated, leaving a staggering 72% untreated. This untreated wastewater poses serious environmental risks by polluting rivers, lakes, and soil. However, it also presents an opportunity to address the ongoing water crisis in the country.

Current Situation

The rapid urbanization and industrial growth in India exacerbate water scarcity and climate change further complicates the situation. The Centre for Science and Environment (CSE) and the National Mission for Clean Ganga (NMCG) released a report denoting the potential of treated wastewater as a resource. The report advocates for its use in irrigation, industry, and urban greening to enhance water security.

Government Initiatives

The Ministry of Jal Shakti mandates that cities recycle at least 20% of their water. Despite this requirement, the necessary treatment infrastructure and implementation strategies are lacking. Some cities, like Nagpur and Bengaluru, have progressed in utilizing treated wastewater for various purposes, including agriculture and groundwater recharge.

Regional Policies

States such as Maharashtra and Gujarat have implemented policies to promote wastewater reuse in agriculture and industry. These initiatives are essential for sustainable water management. However, several challenges remain, including infrastructure gaps, public resistance, and high costs associated with wastewater treatment.

Proposed Solutions

The report suggests adopting decentralised and cost-effective technologies for wastewater treatment, emphasises the need to align policies with urban and industrial requirements. Public-private partnerships can also play important role in overcoming existing barriers.

Integration into National Programs

Integrating wastewater reuse into national water programmes, such as the Jal Jeevan Mission and Atal Bhujal Yojana, is essential. This integration can help establish a climate-resilient water management system.

The report analyses 35 case studies across 16 cities, illustrating the potential of treated wastewater as a valuable resource. By prioritising wastewater reuse, India can encourage a circular economy that promotes sustainable and equitable water management for all.
