SDG 6: Clean Water and Sanitation

How we research clean water, treat and recycle all the water our campuses use, handle waste safely, and help nearby communities get clean water and better sanitation.

Research spotlights

Sewage into clean water and energy

Prof Bhawna Yadav Lamba's DST-funded microalgae plant treats sewage from a municipal canal, reclaims the water and turns the algae and sludge into bio-oil, biogas and bio-fertiliser. Built with the NGO Vikalp Nai Dishayen, it has reached Technology Readiness Level 7.

Sensors to catch contamination

Prof Ashish Mathur's team develops low-cost sensors that detect heavy metals and harmful microbes in drinking water, presented at IFAWET-2025, which UPES co-hosted.

Microplastics in rivers and lakes

With Technische Hochschule Bingen, UPES researchers compiled microplastic data from German rivers, groundwater and treatment plants and proposed harmonised measurement protocols (2025). A second review of 127 studies compared Himalayan lakes with the Alps and Andes and proposed monitoring and clean-up frameworks for high-altitude lakes (2025).

Water for mountain villages

HILL is working with French institutions on water quality and availability under climate change, and building a simple solar thermal water purifier for villages in hilly terrain. A separate project studies water quality and microplastics in slum communities along Dehradun's urban rivers.

2Water on campus

UPES treats its own drinking water, recycles all its wastewater and recharges groundwater on both campuses.

650 KLDsewage treatment capacity (350 Bidholi, 300 Kandoli)
89%water savings through recharge and reuse
0untreated wastewater discharged
  • Safe drinking water. Water treatment plants on the Bidholi and Kandoli campuses, with UV filtration, supply potable water through a network of storage tanks, pumps and pipelines to academic buildings, hostels and other facilities.
  • Careful use of groundwater. Six bore wells meet daily needs, with extraction managed alongside conservation measures.
  • No more wasteful RO. After tests confirmed the supply was safe to drink, UPES removed reverse-osmosis purifiers, which waste about three litres for every litre purified, and switched entirely to UV-treated water, which also keeps essential minerals in drinking water. The Vice Chancellor highlighted the change at Sustainability Fair 3.0 in April 2025.
  • Zero water discharge. Sewage treatment plants of 350 KLD at Bidholi and 300 KLD at Kandoli recycle all campus wastewater, with more than 250 kilolitres a day reused for landscaping, horticulture and other non-drinking uses.
  • Rainwater. Harvesting pits fitted with flow meters recharge groundwater and reduce reliance on outside supplies.

Policy

The UPES Energy, Environment & Sustainability Policy (2025) commits the university to rainwater harvesting and efficient water management, water-efficient fixtures across campus, wastewater recycling and responsible discharge, regular monitoring and maintenance of water supply systems, safe disposal and treatment of wastewater, and preventing contamination of natural water sources (§5.2, §5.3.2). An Energy, Environment & Sustainability Committee monitors resource use and reports on it.

3Sanitation and safe waste handling

UPES keeps its campuses hygienic and stops waste from polluting water and soil.

  • Five waste streams. Waste is separated where it is produced into wet organic waste, dry recyclables, hazardous waste such as chemical containers and used oil, e-waste, and biomedical and sanitary waste.
  • Authorised disposal. Every stream is collected, stored, transported and disposed of through authorised agencies in line with environmental regulations, with recycling preferred over landfill.
  • Menstrual hygiene. Sanitary napkin vending machines are installed in girls' hostels, and sanitary waste is handled as biomedical waste.

4Water and sanitation in the community

UPES students and partners bring clean water, sanitation and hygiene education to villages, schools and rivers around Dehradun.

  • River clean-ups. Through Project Naraini, the student group GS3 has run five river-cleaning drives in Dehradun.
  • Water for villages. Srijan interns working with Urvita assessed community water needs and helped install water filters, and those working with Bhawana Sewa Sansthan helped restore wells and ponds under the Jal Jeevan Mission.
  • Hygiene education. GS3's Project Ayushman taught hygiene and resource conservation to about 1,000 students in eight government schools, and NSS volunteers ran water conservation workshops during Swachhta Pakhwara.
  • Menstrual health. Project Lakhon Khawahishen gave reusable menstrual cups and training to about 1,200 women, and GS3's Project Sakhi reached more than 1,000 girls in 10 government schools.
  • Jal Samadhan. During its seven-day camp in April 2023, NSS UPES held a water-conservation day in Bidholi village with a rally on rainwater harvesting, an explanation of how it works, live working models and a street play.
  • Model villages. Project Utthan works on sanitation, health and clean energy with the villages of Dhalani and Koti, and Project Swachhata runs cleanliness drives in nearby communities.
  • Public dialogue. From 6 to 8 August 2025 UPES hosted the 5th International Forum on Asian Water Environment Technology (IFAWET-5) with the University of Tokyo, Tecnológico de Monterrey, the National Institute of Hydrology and IIT Roorkee, with participants from 12 countries. At Himalaya Calling 2025, engineers, scientists and local practitioners discussed nature-based solutions for Himalayan rivers, and ICMS 2025 applied mathematics to water-resource management.
