Policy Frameworks for Wastewater Recycling and Circular Water Economy
Source:The Hindu ↗
কেন এটি গুরুত্বপূর্ণ
As India grapples with acute water stress, groundwater depletion, and river pollution, shifting toward wastewater recycling and a circular water economy is critical for sustainable development and national water security.
সারসংক্ষেপ
The article emphasizes the urgent need for India to adopt robust policy frameworks and infrastructure for the reuse of treated wastewater. Highlighting the shortfall in sewage treatment and widespread water stress, it argues for transitioning toward a circular water economy by mandating treated water utilization in agriculture, industrial cooling, and urban utilities to preserve depleting freshwater resources.
মূল বিষয়
- India faces severe water scarcity, making the management and reuse of treated wastewater an urgent imperative rather than an option.
- Most sewage treatment plants (STPs) underperform, and a large fraction of wastewater remains untreated, polluting rivers and groundwater aquifers.
- A comprehensive national policy framework is required to mandate treated wastewater reuse in non-potable sectors like agriculture, industry, thermal power plants, and urban landscaping.
- Economic incentives, pricing mechanisms, and decentralized treatment infrastructure are essential to shift from linear water consumption models to a circular water economy.

mandating treated wastewater reuse across all states uniformly
Aspirants often assume India's National Water Policy legally mandates and enforces penal actions for wastewater reuse across all states, whereas water is a State subject under Entry 17 of the State List.

What are the key institutional mechanisms and legal frameworks for water pollution control in India?
- CPCB Role: Statutory body established in 1974 under the Water (Prevention and Control of Pollution) Act to coordinate state boards and set standards.
- Regulatory Powers: Enforces consent to establish and consent to operate mechanisms for industries discharging effluents into water bodies.
- National Water Policy: Comprehensive framework addressing water allocation priorities, emphasizing water as a scarce economic good, and promoting recycling.

Circular Economy + Urban Local Governance
Urban local bodies shifting from pure service providers to commercial water-utility vendors creates new dimensions for municipal governance under the 74th Constitutional Amendment.
Water Security + Energy Transition Nexus
Substituting freshwater with treated wastewater in thermal power plants directly impacts industrial compliance costs and eases agricultural-urban water conflicts.
