Sustainable Environment at BITS Pilani, Pilani Campus

Sustainability

Campus is steadily moving towards sustainability in electricity, water & uses of natural resources. Water conservation and systematic distribution of portable water supply is managed and monitored efficiently. Water used by campus residents is treated scientifically and recycled back to use in the campus, where as the recycled water is being reused in flushing systems & in horticulture work. Our aim is to make it zero discharge campus.

Campus had also aimed to reduce its dependence on conventional power. In this regard, solar power plants and energy saving fixtures have been introduced and installed in the campus.

Usage of transport in the campus is very limited, where as Battery operated vehicles are being introduced in campus for transportation. 5000+ students residing in the campus are not permitted to use their private transport inside the campus and are encouraged to use cycles for their local movement inside the campus & public transportation for outside the campus.

Energy Conservation

In campus total 949.12 KWp of on grid roof top solar power plant installed and commissioned to use of renewable energy in the campus & it is planned to commission about 45 KWp roof top solar power plant by end of December month in this year.

Total 26 Nos. standalone solar powered street lights are installed in the campus, which is estimated to save around 9, 90 kW of electricity annually.
Around 80 Nos. of the street lights out of 495 in the campus are connected to off-grid solar power plant of 18.5 kW per day. These street lights work on solar power for about eight to ten hours every night, which is estimated to save around 6,753 kW of electricity annually. After exhausting the solar power, these street lights function on conventional power.
Since 2014, hostels, residential quarters, academic and administrative blocks constructed as part of the infrastructure expansion by Project Parivartan, replace all CFL, Metal Hallide, Fluorescent tube lights are provided with LED fixtures to reduce consumption of energy.
Similarly existing CFL, tube lights and other electrical fixtures are being replaced with energy saving LED fixtures in a phased manner.

In campus 28 nos. (Each carry 2 nos. of four wheelers) of car parking stand having standalone solar powered lights, able to park 56 nos. of four wheelers.
In campus all the newly renovated hostel’s toilet lights & exhaust fans working are controlled with motion sensor to save electricity.
In campus all street lights (Total No.495) fixtures are LED type.
In campus all street lights (Total 495 Nos.) on/off with LDR, as per sun light intensity availability. No need to change time as seasons change.

Water Conservation

Six groundwater recharge points are created across the campus. In this, the surface runoff water during monsoon is directed to a designated area which then percolates in the ground resulting in groundwater recharge. Many such recharge points are being planned across the campus in the coming years.
All overhead tanks and water coolers are fitted with floats, sensors and other mechanisms to shut the water supply and avoid overflow.
Overhead tanks which are filled with pressurized supply of water through pumps are fitted with actuator valves for avoiding overflow.
Insulation on water storage tank at Ram & Budh Bhawan to guard against extreme temperature.

VFD based hydro pneumatic system.
Pumps & equipments selected on ‘’best ‘energy efficiency point.
Use of low flow fixtures.
Use of treated water with BOD less than 10 ppm and COD less than 50 ppm from STP for HVAC cooling tower make up ,flushing and irrigation.

Irrigation water Network

Irrigation water for landscape use within the campus is a domestic quality and it sourced from in house STP and has acceptable parameter as per governing requirement, using it to maintain lush green garden.

Recycling

Domestic waste generated in the campus at residences, hostels, messes, etc. is segregated at source into dry, wet waste.
To maintain natural balance in the environment and make optimum utilization of waste available, the biodegradable waste is being processed.
The Solid waste management Facility is being developed in the campus with 2 Ton per day capacity organic waste processing plant to treat wet/ organic waste generated by the residents of campus & kitchen facilities.
The plant produces bio-gas which store & use to generate electric power using Bio gas Generator.
The by-product of the plant is organic manure that is used as a soil improviser.
The two Sewage Treatment Plant (STP) with the capacity of 1 MLD & 1.5 MLD each is working round the clock to treat sewage generated by residents of the campus.
Flushing water sourced from in-house sewage Treatment plant. The Treated Effluent for flushing is obtained after tertiary treatment at STP. Treated effluent is odorless and shall is acceptable chemical /bacteriological parameters as per Rajasthan pollution control boards laws. Recently some hostels, STP treated water is supplied to flush tanks of EWC through dedicated supply network.
The sludge generated at STP is transferred to drying bed in the vicinity of STP which is used as manure after drying.
