Water Sources, Quality and Usage

WATER SOURCES, QUALITY AND USAGE

The University’s estimated water usage is 483 kilolitres per day, but calculations based on standard benchmarks suggest an average daily requirement of approximately 662 kilolitres. This discrepancy is addressed by supplementing freshwater use with recycled wastewater, a commendable practice that supports sustainability. Most of the University’s water is sourced from borewells, complemented by 300 kilolitres per day of treated wastewater for greening purposes. Water is stored in 33 tanks—18 overhead, 11 on-ground, and 4 for recycled water—and is distributed via a pipeline system to 3,424 taps and 800 cisterns. With taps designed to deliver 12-14 litres per minute, the University ensures efficient water usage for drinking, domestic, and greening needs. Regular quality checks confirm that borewell water meets potable standards, ensuring safe and sustainable water for all University activities.

Current Water Conservation Measures at the University:

The University features a well-designed network of water storage tanks and distribution pipelines equipped with control and float valves to minimize wastage from overflows. Out of the 17 tubewells, one and three of the 18 overhead tanks are fitted with auto-shutoff mechanisms to prevent overflow, with regular inspections ensuring prompt repairs for any leaks. Additionally, 15% of taps have timers and sensors, while 20% are equipped with water-saving technologies like aerators. The sewage system is separate from the stormwater system, treating wastewater to safe discharge levels before reusing it for greening. Rainwater harvesting is also implemented, with stormwater directed into five unlined percolation tanks for groundwater recharge. To promote water conservation, the university raises awareness through signage, events, and encourages student innovation in water-saving initiatives, all under its Environmental Policy of “Recycle, Reuse, Reduce, and Recover.”

Some storage tanks on campuses are equipped with indicators and float valves to alert users about overflows. Additionally, sprinklers and drip irrigation systems have been installed in various areas, including lawns and orchards, with potential for further expansion. While the campuses have effective channelised systems for rainwater harvesting and percolation tanks for groundwater recharge, they currently need a dedicated rainwater harvesting structure. To address this, a “Zero Rainwater Flow Out” plan is recommended to determine the number, types, and locations of groundwater recharge structures needed to utilise the University’s rainwater fully.
