Quick Revision: Decentralised Modular Wastewater Treatment Systems (DEWATS) are low-cost, scalable solutions that treat sewage at source, reducing pollution and public health risks while aligning with SDG 6.

Why is this in the news?

A 20-year-old innovator from Madhubani, Bihar, developed a low-cost, modular wastewater treatment system inspired by the sanitation challenges observed in Mumbai’s slums. The technology has been recognised by the United Nations Development Programme (UNDP), highlighting its potential for scalable, decentralised water purification solutions in resource-constrained settings. This development underscores the intersection of grassroots innovation, public health, and international development frameworks.

Background

• India generates approximately 1,800 crore litres of wastewater daily, with only 20–30% undergoing treatment, leading to severe water pollution and public health risks such as waterborne diseases.
• The National Urban Sanitation Policy (2008) and subsequent initiatives like Swachh Bharat Mission 2.0 and AMRUT emphasise the need for sustainable urban sanitation and wastewater management.
• The United Nations Sustainable Development Goal 6 (SDG 6) mandates universal access to safe drinking water and sanitation, including improved wastewater management by 2030.
• Decentralised Wastewater Treatment Systems (DEWATS) are emerging as viable alternatives to large-scale, capital-intensive treatment plants, particularly in peri-urban and slum areas.
• Technological innovations in water purification have gained prominence in India, with startups and individuals contributing to low-cost, scalable solutions for underserved communities.

What is a Decentralised Modular Wastewater Treatment System?

• A decentralised modular wastewater treatment system is a small-scale, locally deployable unit designed to treat sewage and greywater at or near the source of generation, eliminating the need for extensive sewerage networks.
• These systems utilise physical, biological, and chemical processes—without harmful chemical dosing—to remove contaminants, pathogens, and organic matter from wastewater.
• Modularity allows for customisation based on the volume of wastewater, land availability, and local environmental conditions, making them adaptable to diverse settings such as slums, rural areas, and small industries.
• The technology developed by the innovator employs a low-cost, energy-efficient design, reducing the capital expenditure for wastewater treatment from ₹20 lakh (traditional systems) to ₹5–7 lakh.
• Such systems contribute to public health by mitigating the spread of waterborne diseases (e.g., cholera, dengue, malaria) linked to untreated wastewater in densely populated areas.
• The recognition by UNDP aligns with global efforts to promote affordable and innovative technologies under the United Nations Technology Bank for Least Developed Countries.
• Decentralised systems also support water reuse and recycling, reducing pressure on freshwater resources and promoting circular economy principles in water management.

Key Features

Feature	Significance
Decentralised and modular wastewater treatment system	Enables scalable, on-site purification without large infrastructure, reducing dependency on centralised sewage systems
Chemical-free purification process	Eliminates secondary pollution risks from residual chemicals, aligning with sustainable development goals

Why it Matters

Environmental Impact

• Addresses critical gap in India’s wastewater treatment capacity, where only 20–30% of 1,800 crore litres of daily effluent is treated, reducing waterborne disease transmission in urban slums
• Promotes circular economy by enabling reuse of treated water in non-potable applications, conserving freshwater resources

Technological Innovation

• Demonstrates grassroots-level engineering solutions to complex urban challenges, bypassing traditional academic pathways via experiential learning
• Leverages low-cost, locally repairable components to ensure sustainability in resource-constrained settings

Policy Relevance

• Aligns with India’s National Urban Sanitation Policy (2008) and Jal Jeevan Mission’s ‘Greywater Management’ guidelines
• Supports implementation of Swachh Bharat Mission 2.0’s focus on faecal sludge and septage management in peri-urban areas

Socio-Economic Upliftment

• Reduces healthcare burden on marginalised communities by mitigating vector-borne diseases linked to stagnant wastewater
• Creates opportunities for local entrepreneurship in wastewater management, aligning with ‘Atmanirbhar Bharat’ principles

Challenges

1. Scalability and Standardisation

• Lack of uniform technical standards for decentralised systems may hinder widespread adoption across diverse urban contexts
• Regulatory ambiguity in certification of non-conventional treatment technologies delays deployment in municipal projects

UPSC Link: GS-III: Urbanisation

2. Financial Sustainability

• High initial capital expenditure for small enterprises despite cost reduction, requiring innovative financing models (e.g., blended finance)
• Absence of clear revenue streams for operators post-installation, limiting long-term viability

UPSC Link: GS-III: Resource Mobilisation

3. Public Acceptance and Behavioural Change

• Skepticism towards non-conventional systems due to entrenched reliance on conventional sewage networks
• Need for community engagement to ensure proper operation and maintenance of decentralised units

UPSC Link: GS-II: Governance

4. Technical and Operational Constraints

• Vulnerability to extreme weather events disrupting modular systems in flood-prone areas
• Limited local technical expertise for repair and maintenance, necessitating capacity-building programmes

UPSC Link: GS-III: Science & Tech

5. Data and Monitoring Gaps

• Absence of real-time performance monitoring frameworks for decentralised systems, impeding evidence-based policymaking
• Inadequate integration with existing urban water management databases

UPSC Link: GS-III: Disaster Management

Challenges — UPSC Perspective

Issue	Concern
Regulatory hurdles	Non-recognition of decentralised systems in municipal wastewater bye-laws
Skill deficit	Shortage of trained personnel for installation and maintenance
Financing gaps	Limited access to credit for small entrepreneurs in wastewater sector
Public health risks	Potential for untreated effluent reuse in agriculture without safeguards

Way Forward

• Establish a national certification framework for decentralised wastewater treatment technologies under the Ministry of Housing and Urban Affairs
• Integrate the system into Smart Cities Mission’s ‘Water Plus’ framework to incentivise adoption in model urban areas
• Launch a credit-linked subsidy scheme for MSMEs adopting low-cost treatment systems, in collaboration with NABARD
• Develop a national-level technical training programme for local operators, in partnership with IITs and state pollution control boards
• Create a real-time monitoring portal for decentralised systems, linked to the Jal Jeevan Mission’s dashboard
• Amend municipal bye-laws to mandate decentralised treatment for new constructions in notified slum areas
• Facilitate PPP models for large-scale deployment, with performance-based contracts for private operators

UPSC Value Addition

Prelims Practice Questions

Q1. Consider the following statements regarding wastewater treatment in India:
1. India generates approximately 1800 crore litres of wastewater daily.
2. Only 20-30% of this wastewater undergoes treatment before disposal.
3. The traditional wastewater treatment systems for small industries cost around ₹20 lakh.
4. Decentralised wastewater treatment systems typically require chemical dosing for effective purification.

How many of the above statements are correct?

1. Only one
2. Only two
3. Only three
4. All four

Answer: Only three — Statements 1, 2, and 3 are correct. Statement 4 is incorrect because the decentralised system developed by Piyush Jhajharia does not rely on chemical dosing.

Q2. Assertion (A): The United Nations Development Programme (UNDP) recognises grassroots innovations that align with Sustainable Development Goals (SDGs).
