KISS-DU’s Sustainable Approach Towards Water Management

KISS Deemed to be University has been meeting the Sustainable Development Goals (SDGs) of the United Nations since its inception. In an endeavour to meet SDG – 3 (Good Health and Well-Being), SDG – 6 (Clean Water and Sanitation), and SDG – 7 (Affordable and Clean Energy) the University has taken initiatives in order to improve the quality of life on campus. It includes rainwater harvesting, bore-well and open well recharge, construction of tanks and bunds, wastewater recycling and ensuring maintenance of water bodies and distribution system in its premises.

Rainwater harvesting

KISS-DU has adopted a rooftop rainwater-based groundwater recharge system. Groundwater recharging is an excellent rainwater-capturing process. Any quantity of rainwater may be channelized to replenish the groundwater level of the surrounding areas. The average water recharged annually
from the rooftop at KISS-DU is 10980 Cu. M

Tabular representation of water recharged annually from the rooftop:

Sl No Infrastructure Area in Square Feet
01 Administrative Building 12,400 sq.ft
02 Academic Building 17,100 sq.ft
03 Old Girls’ Hostel 36,400 sq. ft
04 Academic Block 13,800 sq.ft
05 New Girls’ Hostel 16,600 sq.ft
06 Boys’ Hostel – 1 15,600 sq.ft
07 Boys’ Hostel – 2 20,100 sq.ft

Bore-well/Open well recharge

Rainwater collected at the rooftop in the various buildings is redirected through PVC pipes and dynamic rainwater filters to defunct and functioning borewells.

Construction of tanks and bunds

Storm water and surplus rainwater that cannot be channelized to the borewells is sent over to the large open waterbodies within the campus, such as pond 1 and pond 2, which together span a total area of 15.5 acres.

Wastewater recycling

Wastewater from various academic buildings, hostels, and kitchens is treated in three Sewage Treatment Plant (STP), with a total capacity of 2750 Kilometers per day (KLD), meaning 2750000 litres per day. The treated water is pumped back for watering the plants on the various campuses.

Maintenance of water bodies and distribution system in the campus

Mechanism for maintenance of large water bodies located at KISS Campus

There are two ponds located on the premises of KISS. The sizes are 9 acres and 6.5 acres (respectively) and spread adjacent to the playground and plantation area. The entire pond bank is planted with large, selected trees (low leaf fall).

A team comprising gardeners and supervisors have been entrusted with the responsibility of taking care of the plantation and bond cleaning activities. The garden waste is put in composting pits located nearby.

The water body is in an open area so that it gets natural air.  There are lot of IMC variety fishes in the pond and aquaculture facilities are facilitated. A fibre casted paddling boat moves inside the pond to feed the fishes. The ponds contribute to holding and enhancing of ground water level. Further, the quality of water is tested from time to time in order to monitor the common parameters. There is an arrangement to siphon the water from one pond to other for recirculation purpose.

Water distribution mechanism at KISS

KISS-DU has a structured and well-planned water distribution mechanism. The water is pumped from bore-wells to the overhead tanks located on each building. Then water is channelized for utilities through suitable sized pipes and valves. The pumping system is equipped with automatic overflow control / level controller. In order to ensure that the water is safe and free from bacteria, high flow capacity UV chambers have been installed near each bore-well. The output from the pump is passed through UV chambers before entering to the overhead tanks. The UV treated water is allowed directly from the overhead tanks for general purposes. The water is fed to RO (Reverse Osmosis) based water treatment units located in different utility points specifically for drinking purposes. Separate tap points have been provided for the convenience of the students and for cooking purpose the water is supplied from solar heating system located on the rooftop by using warm water. This reduces the consumption of time and fuel.

Wastewater is channelized to sewage treatment plants located at different locations. We have 450 KLD, 1000 KLD and 750 KLD STPs. The treated water from wastewater treatment plants is used for plantation and gardening purposes and excess treated water is allowed to drain out from the campus.

Central R.O. Based Water Treatment Plants

A central water treatment plant is installed at KISS for the purpose of supplying drinking water to taps throughout the day. It is a reverse osmosis based water treatment plant with TDS and pH regulation arrangement with UV chamber. The capacity is 5000 ltrs / hour. Umpteen number of taps have been installed in order to supply water to the students.
