Amrita continues its commitment toward Sustainable Water Management by enhancing its reuse framework with expanded treatment capacity, digital monitoring, and green campus integration. Across all campuses, wastewater is effectively treated and reused, aligning with SDG 6: Clean Water and Sanitation and the university’s vision of achieving net-zero water loss.
Each Amrita campus operates three advanced Sewage Treatment Plants (STPs) with a total capacity capable of treating 75% of the consumed water, now upgraded with improved aeration systems and sludge handling. The treated water supports toilet flushing, gardening, landscaping, and cooling operations, significantly reducing dependence on freshwater sources.
Flow meters and IoT-based sensors are installed across treatment facilities and distribution tanks to ensure real-time monitoring and transparency in reuse measurement. In 2024, reused water accounted for 73% of total campus water consumption, indicating consistent efficiency improvements from the previous year.

Amrita’s STPs employ aerobic treatment with activated sludge processes, producing treated water with BOD levels below 3 mg/L, exceeding regulatory standards. Laboratory teams at Amritapuri and Coimbatore continuously test samples for compliance, ensuring safety for all non-potable applications.
During dry months, reuse levels rise to 90%, while monsoon periods record slightly reduced ratios due to lower demand. The Faridabad campus STP maintained consistent performance with daily BOD around 3.1 mg/L, confirming operational stability.
Water reuse directly sustains Amrita’s ecological networks, including Aushadavanam herbal gardens, Amritavanam rainforests, and Butterfly Parks across campuses. Over 190,000 trees have been planted by 2024, contributing to groundwater recharge, carbon sequestration, and biodiversity conservation. Treated water supports:
By 2025–26, the university targets an 80% reuse ratio through the addition of a 4 MLD STP and full integration of IoT-based water analytics across all campuses. These initiatives strengthen Amrita’s leadership in sustainable resource management, ensuring efficient, data-driven, and environmentally responsible water reuse.
