Water Audit for the Campus

NitteDU tracks water requirements, waste water generation and water recycling. This is done to inform policy decisions and to create awareness about water conservation amongst it’s stakeholders.

Rainwater harvesting

Being located in region which receives high rainfall during the monsoon season, NitteDU makes efforts to manage and utilize rainwater effectively. Storm water drains separate from the general drainage system are in place.

Rainwater from roofs is collected using separate pipelines. This water is collected in raw water storage tanks which is then treated in a WTP consisting of pressure sand filter and activated carbon filter. Additionally, chlorine demand of the water is assessed and required dosage (Sodium hypochlorite diluted to 10%) is provided using automatic dosage pumps. The water is used for all domestic purposes.

The volume of rainwater in the three campuses is as follows:

  1. Justice K S Hegde Charitable Hospital: Approx. 2 lakhs litres of rainwater is collected with a heavy shower of 30 mins
  2. KSHEMA: Approx. 1.5 lakhs litres of rainwater is collected with a heavy shower of 30 mins
  3. Paneer campus: Approx. 1 lakh litre of rainwater is collected with a heavy shower of 30 mins

Promoting water conservation

Building practices for water conservation
NitteDU consciously incorporates water conservation practices while designing and constructing buildings on its campus.

  • Rejuvenating the Vrishabhavathi river through addressing the built (a student project by Ms. Kavya Amin, Nitte Institute of Architecture)
    • The neighborhood of Malleshwaram, in the city of Bengaluru, was planned for the nobles and high-income class people as a modern hygiene suburb with various communities divided into eight blocks founded in the year 1889. The city being planned to provide a modern lifestyle, is presently a major chaos to the water body flowing through Malleshwaram. The tributary of Vrishabhavathi river that flows through Malleshwaram has been dumped with domestic waste, leaving the urban fabric face its back to the natural water body flowing adjacent to the houses. This concern of the river losing its importance and identity to the people and the city itself is the major identified problem in most cities. The lifestyle of the people is enhanced with the kind of context they live in. It's important to create public landscaping which creates a mutual beneficial relationship between the city dwellers and their environment. Thus, the aim of this proposal is to develop the canal edge by providing the ideal green buffer space for the development of the ecosystem which further enhances the engagement of the people with the water body. It is important for the urban fabric to be moulded in such a way as to encourage the community spaces in and out to connect with the natural sources present around. The proposal aims on the combination of a housing typology and the urban green spaces developing an ideal scenario in layering the urban fabric.
  • Rejuvenation project of Sulthan Battery and its immediate context (A student project by Mr. Harikiran, Ms. Shahana and Ms. Nabeela, Nitte Institute of Architecture)
    • Rivers have been playing a vital role in human history and have given birth to ancient civilizations. From the source of food to life ranging from day-to-day activities to large-scale trading.Rivers and land as a part of nature have been always been together, negotiating, shaping, and have no separate boundaries between them.But sadly, due to unplanned modern advancements and lifestyles, rivers are mainly feared, ignored, and have been differentiated. Man, due to his personal needs has been intervening between them, often causing self-destruction due to floods or drought. Mangalore, being a coastal region, celebrates its association with the sea through beaches. But what not the river. So through our studies, we have understood the present condition of the city, and its association with the river, and why it is isolated, due to several reasons like lack of accessibility, sanitation, or lack of infrastructure. Based on our studies we have made an attempt to create an opportunity to celebrate rivers and connect with them. Not to change the nature of the river, but to reclaim it and celebrate it.
  • Promotion of rainwater harvesting off-campus - NitteDU purchases rainwater via a dedicated pipeline from an artificially created rainwater harvesting pond from an external location near the campus. This promotes rainwater harvesting storage at this off-campus location.

Water Recycling

Use of recycled water for gardening and toilet flushing purposes. The wastewater is collected and treated in Sewage Treatment Plants (STP). Three campus have individual STPs. The KSHEMA campus has a STP plant of handling capacity of 4,00,000 liters/day. University and Hospital campus have a plant of 8,00,000 liters/day and Paneer campus has a plant handling 2,50,000 liters/day.

Water safety and quality

All students, employees and visitors to the constituent units, sections, and centres of NitteDU have free access to clean drinking water. Drinking water is available through UV based water purifier dispensers. The quality of water is assessed periodically through both in-house and external testing.

All major buildings have separate storage facilities for potable and non-potable water. Segregated storage tanks and pipelines are available for potable water, stormwater and grey water.

Medicinal Gardens

The KSHEMA campus as well as Paneer campus have medicinal gardens. A total of 125 medicinal plants are planted and cataloged for its scientific name, common name, medicinal uses and their major chemical components reported.

Indoor plants

The A.B. Shetty Memorial Institute of Dental Sciences is in the University Campus. Although this campus has the least green cover as compared to Paneer or Medical College campus, they have a good practice that targets the improvement of indoor air quality. Every common room has indoor plants which is well tended and provides healthy oxygen rich air and reduce the carbon-di-oxide released by the human occupants. The Institute has always supported the concept of Clean City Green City in college by various initiatives.

Kitchen and a terrace garden

Nitte Institute of Architecture has developed a kitchen garden as well as a terrace garden to educate the students on the design of urban horticultural practices. The kitchen garden has several vegetable crops and the a terrace garden has over 50 fruit trees such as Figs, Jamoon, Chikoo, Guava, Mango, Lemon etc.

Tree Adoption

The Students of Nitte University Centre for Science Education and Research has a good practice of tree adoption. Undergraduate student volunteers have adopted several trees on campus. They ensure proper watering and care during the dry months of summer. Weak saplings are preferred for adoption over healthy trees.


Students actively participate in the Swachh Bharath Programs conducted regularly by the NSS unit of the University. 39 programs with nearly 4000 students and staff participation was recorded over a period for last four years. Vanamahostava is conducted during the first week of July by tree planting and conducting awareness programs. The world environment day is also conducted in the campus by planting saplings and the theme of the United Nation is deliberated eg. “Connecting people to Nature” in 2017 and “Beat plastic pollution” in 2018.

Plant a Tree on your a Birthday

Planting a sapling on birthdays is like leaving something memorable for the campus community and one can enjoy that excitement whenever they visit the campus later in life. Birthdays can be made memorable and in turn, we can improve the biodiversity of the university campus. Behalf of Nitte University Green Initiative Project (NUGIP) started “Plant a Tree on Your Birthday” in KSHEMA campus for the teaching staff. The initiative, ‘Plant a Tree on your Birthday’ was launched with the first sapling sharing its birthday with Prof. Dr. Satheesh Kumar Bhandary, Dean, KSHEMA and Prof. Dr. Sukanya Shetty, HOD, Biochemistry. Dr. Jayaprakash Shetty, Registrar KSHEMA, Dr. Smith Hegde, NUGIP Co-ordinator, Dr. Sumalatha Shetty, NSS Co-ordinator, Mr. Shashi kumar Shetty, NUGIP Green Officer (KSHEMA Campus), Dr. Nanjesh and Dr. Sachin, NSS Program Officer were present on the event.

Regular planting drives are conducted to maintain a green and clean campus. Recommendation made by the committee is implemented in the new developmental plans of the University. The University campus conducts regular air and water quality testing to confirm the availability of healthy water and air. The tests are conducted by an independent agency and validated. All parameters tested are well within the permissible limits. Thus clean air and water supply is maintained on campus.

Common transport facilities

Staff, students and other employees are strongly encouraged to avail the common transport facilities provided by the University. There are 16 buses which cater to the common mode of transportation. An additional of 6 vans of 14 seater capacity regularly commute between campuses and city to transport staff, students and other employees of the University.

The staff and students of the University have conducted several programs in-house, as well as in public schools to create awareness on cleanliness, vaccination and hygiene.

Towards a greener future

NitteDU is poised to expand its campus in Mangalore. A 100-acre parcel of land near the current campus has been ear-marked for development of new campus. In line with its commitment to creating sustainable and re-generative spaces that have minimal impact on the environment, the masterplan for developing these associated grounds is based on key strategies specific to the site that helps NitteDU set exemplary standards in the domain of sustainable landscapes.

India has pledged in the Paris Agreement 2015 to reduce emissions by 30-35% below the 2005 emission intensity of GDP by 2030. Hence aligning with the 8 missions identified under National Action Plan for Climate Change, the following fundamental concepts have been considered in the campus master planning process:

  • Micro Climate Modifications
  • Efficient Water Cycle
  • Clean Energy
  • Ecological and Biodiversity Enhancement

One of the key aspects of the plans for this development is the preservation of existing water bodies and tree cover in the land. The water bodies sustained by rainwater which will be important source of water for the campus community. These water bodies will also help in preserving and supporting the biodiversity of the campus.
