Pre- Feasibility Report

INTRODUCTION

Indian Institute of Technology-Delhi is one of the seven IT Institutes created as centres of

excellence for higher training, research and development in science, engineering and technology

in India, the others being at Kanpur, Kharagpur, Madras, Bombay, Guwahati and Roorkee.

Established as College of Engineering in 1961, the Institute was later declared an Institution of

National Importance under the "Institutes of Technology (Amendment) Act, 1963" and was

renamed ‘Indian Institute of Technology (IIT) - Delhi’. It was then accorded the status of a

deemed university with powers to decide its own academic policy, to conduct its own

examinations, and to award its own degrees.

The total area of IIT, Delhi campus measures 312.5 Acre (12, 64,727 sqm).

The project was earlier granted Environment Clearance by SEIAA, Delhi vide letter no.

42/DPCC/ SEIAA-SEAC/10/1429-33 dated 11.11.2010 for addition of three blocks viz.,

Professors’ Apartments, Mini Academic Block & New Boys’ Hostel with built-up area =

1,61,919 m2. Post addition of these three blocks, the total built-up area of campus became 6,

42,560 sqm.

IIT, Delhi proposes modification and expansion of the campus with addition of nine new blocks

in the campus viz.

Nalanda Hostel,

GH Keswani Research Centre,

Boys Hostel ‘E’,

Indoor Sports Complex,

Activity Centre,

Research and Innovation Park,

Assistant Professor’s Apartment,

New Girls Hostel,

Shopping Complex

There is also some demolition and redevelopment involved in Nalanda Hostel, Boys Hostel ‘E’,

New Girls Hostel and Shopping Complex.




As a result of modification and expansion (i.e. addition of above-said nine blocks), the built-up

area of campus will increase by 1,35,330.07 sqm. Hence, the total (existing + modification and

expansion) built-up area is estimated to be 7,70,563.07 sqm.

Figure 3: ETP Scheme

Solids removal:

Most solids can be removed using simple sedimentation techniques with the solids

recovered as slurry or sludge. Very fine solids and solids with densities close to one

pose special problems. In such case filtration or ultra-filtration may be required.

Alternatively, flocculation may be used using alum salts or the addition of poly-

electrolytes

Acids and alkalis:

Acids and alkalis can usually be neutralized under controlled conditions. Neutralization

frequently produces a precipitate that will require treatment as a solid residue that may

also be toxic. In some cases, gasses may be evolved requiring treatment for the gas

stream. Some other forms of treatment are usually required following neutralization.

Waste streams rich in hardness ions as from de-ionization processes can readily loose

the hardness ions in a build-up of precipitated calcium and magnesium salts. This




precipitation process can cause severe furring of pipes and can, in extreme cases,

because the blockage of disposal pipe.

Fine Screening:

The use of fine screens for the purpose of removing from the sewage a part of the

suspended solids is a recognized method of sewage treatment.

Advance Oxidation Process:

It is proposed to use Fenton’s reagent (H2O2 + Fe SO4) as advance oxidation process to

oxidise the toxic organics present in the laboratory effluent.

SEWAGE TREATMENT SCHEME

Sewerage System:

The sewage network shall collect the sewage from new buildings which will flow by

gravity to the existing Sewage Treatment Plant.

Following are the benefits of Sewage Treatment Plant:

• Reduced net daily water requirements from tube wells, source for Horticultural

purposes by utilization of the treated waste water. This shall consequently lead to

a lower withdrawal from the underground aquifer water sources.

• Reduced dependence on the public utilities for water supply and sewerage systems.

• Sludge generated from the Sewage Treatment Plant shall be rich in organic

content and an excellent fertilizer for horticultural purposes.

A brief description of the sewage treatment technology is given below:

Membrane Bio – Reactor is among the latest technologies in bio-chemical treatment.

It is designed to produce high quality treated water from wastewater with highest

possible contaminant reduction without using any chemicals. The characteristics of

the MBR process is the use of revolutionary submerged micro and ultra-filtration

membranes in the biological process water tank, to produce high quality permeate

from domestic sewage, primary and secondary wastewater, etc. The submerged

membranes used in the biological process water tank totally removes suspended

sludge from the activated sludge liquid and long term stable MBR operation is

achieved with high permeate flow rates.

Advantages of MBR:

• Low energy consumption (0.30 kwh/m3) for filtration.

• Upto 99.999% removal of total coliform

• Compact, requires ½ to 1/3 spaces over a conventional system.




Figure 4: STP Scheme

RAINWATER HARVESTING PLAN

IIT Campus has an existing storm water drainage system and 105 RWH pits for ground water

recharge.

Additionally, as per the Hon’ble Delhi High Court Order, run-off from campus is being

directed to the internal onsite drains which ultimately join Deer Park, Safdarjang Enclave.

For the proposed expansion/new buildings, 20 RWH pits are proposed to collect the storm

water. The rain water harvesting system will consist of seepage/percolation pits with bore

holes in the middle of the pit.(8” dia) perforated UPVC pipe will be lowered in the middle of

the boreholes and the pit will be filled with gravel / pebbles in three layers, each consists of

boulders(8” dia), gravel (1”-2” dia) & coarse sand. This system is proposed to sustain ground

water table by recharging the aquifer. The mouth of the UPVC pipe shall be protected to

avoid silt getting into the same.

Design specifications of the rain water harvesting plan for new buildings are as follows:

• The roof will have smooth, hard and dense surface which is less likely to be damaged

allowing release of material into the water. Roof painting has been avoided since most

paints contain toxic substances and may peel off.

• All gutter ends will be fitted with a wire mesh screen and a first flush device would be

installed. Most of the debris carried by the water from the rooftop like leaves, plastic

bags and paper pieces will get arrested by the mesh at the terrace outlet and to prevent




contamination by ensuring that the runoff from the first 10-20 minutes of rainfall is

flushed off.

Figure 5: Rain Water Harvesting Pit Design

Run-off generated from new buildings:

Roof top area = Ground coverage = 20,998.035 sqm

Green area = 96,307 sqm

Peak hourly run-off from roof top = 20,998.035 x 0.8 x 0.04 = 672 m3/hr

Peak hourly run-off from green area = 96,3207 x 0.1 x 0.04 = 3853 m3/hr

Total peak hourly run-off from new buildings = 4525 m3/hr

Considering 15 minutes retention time, volume of storm water will become = 1131 m3

Volume of single RWH pit = 𝜋𝑟2h = 3.14 x 1.5 x 1.5 x 5 = 35.32 m3

No. of RWH pits required = 1131/35.32 = 35.02

36 no. of pits are proposed for new buildings for artificial ground water recharge.




SOLID WASTE

The total (existing + modification/expansion) solid waste generated from the project will

be mainly domestic waste and estimated quantity of the same is approx. 12,099 kg/day (@

0.5 kg/capita/day for residential population, 0.25 kg/capita/day for staff/students and 0.15

kg/capita/day for visitors).

The solid waste generated from the existing buildings is approx. 7624 Kg/day.

The solid waste is being managed through an approved agency as per Solid Waste

Management Rules, 2016.

The e-waste generated from the complex is being recycled through an authorised e-waste

management agency.
