A DIVE INTO SANITATION SOLUTIONS: PROCESSING, MANAGING AND TREATING USED WATER

Sanitation systems play a pivotal role in managing wastewater, ensuring public health, and averting environmental pollution.

Types of Sanitation Systems in India:

On-site Sanitation Systems (OSS)

• Twin Pits and Septic Tanks: Utilized in rural areas, these involve alternating usage of twin pits for eco-friendly disposal.
• Other On-site Systems: Bio-digester toilets, bio-tanks, and urine diversion dry toilets offer alternative on-site solutions.

Faecal Sludge Management (FSM)

• Faecal Sludge Treatment Plants (FSTPs): Crucial for on-site sanitation areas, these plants treat faecal sludge, allowing by-products to be reused in agriculture.

Urban Sanitation: Sewer Systems and Treatment Plants

• Underground Networks of Pipes (Sewers): Found in densely populated urban areas, these interconnected pipes transport wastewater to treatment facilities.
• Sewage Treatment Plants (STPs): Utilizing various processes, these plants remove pollutants, showcasing technological innovation for water reuse.

The Necessity of Complex Sanitation Systems:

• Impurities in Used Water: Used water contains organic matter, nutrients, pathogens, and heavy metals, necessitating comprehensive sanitation systems.
• Critical Role: Containment, removal, and treatment of used water are vital to prevent pollution and protect public and environmental health.

Need for Sanitation Systems in India:

• Public Health Impact: Sanitation facilities impact waterborne diseases and overall health; positive results seen in initiatives like the Total Sanitation Campaign.
• Environmental Protection: Discharge of untreated sewage into River Ganga remains a significant pollution source.
• Social and Economic Benefits: Improved sanitation correlates with economic productivity and community well-being.
• Cultural and Societal Dignity: Access to proper sanitation enhances human dignity, especially for women.

India’s Sanitation Status and Achievements:

• Open Defecation Free (ODF) Status: All rural areas declared ODF by October 2019, with over 100 million toilets constructed under Swachh Bharat Mission Gramin.
• Behavioural Change: Campaigns like “Darwaza Band” and community-level programs promote positive sanitation norms.
• Reduction in Open Defecation Rates: Significant decrease observed, particularly in rural areas.
• International Recognition: UN and WHO acknowledge India’s progress in sanitation.

Challenges in Implementation of Sanitation Systems in India:

• Difficulty in Achieving Universal Access: Remote and economically disadvantaged areas face challenges in accessing sanitation facilities.
• Operational Challenges: Maintenance issues observed in some urban areas.
• Affordability and Financial Barriers: Upfront costs hinder implementation, particularly in economically challenged regions.
• Behavioural and Cultural Factors: Deep-seated habits and cultural beliefs impede proper sanitation practices.
• Climate and Geographical Considerations: Certain terrains pose challenges for standard sanitation systems.

The Way Forward:

• Innovations in Technology: Adoption of decentralized sewage treatment plants showcases the potential of innovative technologies.
• Community Engagement and Education: Initiatives like the “Nirmal Gram Puraskar” recognize and reward open-defecation-free villages, promoting community engagement and education.
• Policy and Governance: The National Urban Sanitation Policy provides a framework for planning and developing urban sanitation infrastructure.
• International Cooperation: Collaborative efforts with international organizations, such as World Bank-supported projects, can address sanitation challenges.

Conclusion:

Sanitation systems are indispensable for public health and environmental integrity. By addressing challenges, embracing technological advancements, and fostering international cooperation, India can move towards achieving universal access to safe and efficient sanitation services, contributing to sustainable development.
