Overview
Amrita Vishwa Vidyapeetham is committed to responsible water stewardship through systematic water reuse, recycling, and rainwater harvesting across its campuses. The Water Reuse Policy forms a core component of the university’s Sustainable Campus Policy and supports long-term water security, reduced freshwater extraction, and climate resilience in alignment with SDG 6 (Clean Water and Sanitation) and national water sustainability priorities.
This policy applies to all campuses of Amrita Vishwa Vidyapeetham and integrates infrastructure, technology, monitoring, and stakeholder engagement to maximise the reuse of treated water for non-potable purposes.
This Water Reuse Policy forms part of Amrita Vishwa Vidyapeetham’s Sustainable Campus Policy framework, revised on 12 November 2024 as part of the university’s 2020–2024 sustainability policy cycle.
Policy Objectives
The Water Reuse Policy aims to:
- Reduce dependence on freshwater sources through systematic reuse and recycling
- Promote safe and efficient use of treated wastewater and harvested rainwater
- Integrate water reuse into campus planning, operations, and awareness programmes
- Achieve 40–50% of total campus water demand through recycled water and rainwater by 2025
Scope
This policy applies to all campuses of Amrita Vishwa Vidyapeetham, including academic buildings, hostels, laboratories, utilities, landscaped areas, and shared infrastructure.
Campuses covered
Amaravati | Amritapuri | Bengaluru | Chennai | Coimbatore | Faridabad | Kochi | Mysuru | Nagercoil
Policy Highlights
Greywater Collection and Reuse
- Greywater from sinks, showers, and laundry facilities is collected and treated using dedicated systems.
- Treated greywater is reused safely for landscape irrigation, toilet flushing, cooling and utility applications etc.
- Systems are designed to meet safety and quality standards for non-potable reuse.
Rainwater Harvesting and Groundwater Recharge
- Rainwater harvesting systems are installed across campuses to capture runoff from rooftops and paved surfaces.
- Harvested rainwater is utilised for landscape irrigation, cooling towers and in fire-suppression systems
- Groundwater recharge structures are incorporated to replenish aquifers, improve long-term water availability and maintain ecological balance
Wastewater Recycling and Treatment
- Advanced wastewater treatment plants (STPs) operate across campuses to recycle wastewater.
- Treated wastewater is reused for irrigation, cooling systems and other approved non-potable uses
- All treated effluent meets or exceeds applicable national effluent quality standards prior to reuse or discharge.
Technology and Monitoring
- State-of-the-art treatment and filtration technologies are deployed to improve reuse efficiency.
- Digital systems track volumes of water reused and ontribution of reuse to overall water-demand reduction
- Data supports operational optimisation, compliance reporting, and long-term planning.
Stakeholder Engagement and Awareness
- Students, faculty, and staff are educated on the safety and benefits of recycled water, responsible use of non-potable water systems
- Water reuse concepts are integrated into sustainability training sessions, campus awareness campaigns and educational programmes and outreach activities
Reuse Targets and Continuous Improvement
- Amrita targets meeting 40–50% of total campus water demand through recycled wastewater and harvested rainwater
- Reuse systems are periodically reviewed and expanded based on performance assessments, technological advancements, campus growth and water demand patterns
Governance and Review
The Water Reuse Policy is implemented under the university’s Sustainable Campus framework and is reviewed periodically to ensure alignment with evolving regulatory standards, sustainability goals, and best practices in water management.
Commitment
Through this Water Reuse Policy, Amrita Vishwa Vidyapeetham affirms its commitment to circular water management, climate resilience, and responsible resource use—ensuring that water stewardship remains integral to campus operations, education, and community impact.
