RESPONSIBLE CONSUMPTION AND PRODUCTION
The SDGs arise from challenges like the
economy, ecology and society. Universities can
effect changes in these sectors through their
enterprising talent pool, the spirit of learning
and disseminating information, a conviction for
change; their capacity for research and innovation,
and their ability to engage public stakeholders in
implementing projects. Containing consumption
is a self-explanatory answer to the problem of
sustainability. Beyond that, what is necessary
is to outline meaningful measures backed by
practical and scientific methods to increase
Nitte (DU) practices responsible consumption
The globally accepted model towards improving
sustainability is Reduce, Reuse and Recycle. At
Nitte University, we have endeavoured to identify,
create and implement processes to improve
every area of the 3R model and continuously
improve on the same.
The University has established facilities for
socially relevant action and has built a capacity
to identify and respond to societal needs.
Creating awareness in terms of production and
Nitte (DU) administration and eco-sensitive
Nitte (DU) tracks water requirements, wastewater
generation and water recycling. It is done to
create awareness about water conservation
amongst its stakeholders. An annual water audit
is undertaken across the University to assess per
capita consumption. The audit provides a clear
picture of consumption and helps formulate
containment and improvement measures.
Rain water from roofs is collected using
separate pipelines. This water is collected in raw
water storage tanks and then treated in a WTP
consisting of a pressure sand filter and activated
carbon filter. Additionally, the chlorine demand
of the water is assessed, and the required
dosage (Sodium hypochlorite diluted to 10%) is
provided using automatic dosage pumps.
The water is used for all domestic purposes.
- Use of water-retaining material like cloth/
gunny bags etc., during curing
- Ponding” for retaining water on flat concrete
structures for curing
- Use of curing chemicals/techniques to
minimize water requirements
- Use of non-potable water for construction
- Use of water-efficient plumbing fixtures like
- Use of sensor-based taps
- Use of aerators, pressure inhibitors and flow
regulators to ensure a constant flow
- Separate pipelines for potable water,
water for recycling and treated water are
provisioned for during construction
- Provision for rainwater harvesting
- Provision for management of stormwater
- Rainwater storage ponds have been created
on the campus for the storage of stormwater
- Rainwater from an artificially created storage
pond is used from an external location near
the campus. An MoU has been signed with
the land-owner for the use of this water
- Push cock taps are being used as a
replacement for ordinary taps to reduce
- Old bore wells are flushed to facilitate the
recharge of groundwater.
- Recycled water is used for flushing toilets
and in gardens
- Restrictions on the use of bottled water to
reduce plastic waste.
- Board rooms are equipped with water filters
and dispensers to avoid bottled water.
Nitte (DU) has established STPs of various
capacities on all campuses. Effective utilization
of treated water. Additionally, all buildings have
catered to dual plumbing lines for toilets.
Two methods of treatment at the STP are used:
- Use of recycled water for flushing and
- The wastewater is collected and treated in
Sewage Treatment Plants (STP).
- Three campuses have individual STPs. The
KSHEMA campus has an STP plant with a
handling capacity of 4,00,000 litres/day.
- University and Hospital campuses have a
plant of 8,00,000 litres/day, and the Paneer
campus has a plant handling 2,50,000 litres/
- I. Sequencing Batch Reactor (SBR) System
- II. Continuous Process (Activated Sludge Process)
The process has the following steps:
BAR SCREEN CHAMBER The function of the bar
screen is to prevent the entry of solid particles/
articles above a specific size, such as plastic
cups, paper dishes, polythene bags and sanitary
napkins, into the STP.
EQUALIZATION TANK The equalization tank is
the first collection tank. The primary function
is to act as a buffer, collect the incoming raw
sewage at widely fluctuating rates, and pass it
on to the rest of the STP at a steady flow rate.
AERATION TANK Aeration is the heart of the
treatment system. The primary function of the
Aeration tank is to maintain a high population
level of microbes. This mixture is called MLSS
(Mixed Liquor Suspended Solids). Here the
sewage is mechanically aerated for a calculated
time and left for settling. The clear water is then
taken out using decant valves
INTERMEDIATE SUMP: Clearwater coming out
of the decant valve is collected here. PRESSURE
SAND FILTER (PSF): This unit is a pressure vessel.
It is used as a tertiary treatment unit to trap the
trace amounts of solids which escape the clarifier
ACTIVATED CARBON FILTER (ACF) • This is a
tertiary treatment unit. • Activated carbon is
typically manufactured from coconut shells
or charcoal. • It improves multiple quality
parameters of the water: BOD, COD, clarity
(turbidity), colour and odour.
The University generates
approximately 28.1 Tons/A. The wet waste and
dry waste are sorted at the source. The biogas
unit recycles organic waste to utilize common
A composting facility is available on the Paneer
campus to utilize organic waste. The wet waste
is put into the composting pit, and dry waste
is disposed of using the incinerator. Waste
segregation is done at source in the hospital,
laboratories and common areas. Dedicated bins
for waste management are made available -
Green for degradable, Blue for plastic and metals,
and Red for e-waste and batteries. Bins are
placed in prominent positions on each campus,
with instructions displayed for public awareness.
Strict compliance with provision for disposal of
bio-medical and electronic waste. Chemical and
hazardous waste from laboratories is sent to a
certified agency (RAMKY) for processing, and
no part of the waste is disposed of elsewhere.

through addressing the built (a student
project by Ms Kavya Amin, Nitte Institute of
Architecture), this proposal aims 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. The urban fabric needs to be moulded
in such a way as to encourage the community
spaces in and out to connect with the natural
sources present around them. The proposal
aims to combine a housing typology and
the urban green spaces to develop an ideal
scenario in layering the urban fabric.
