1. INTRODUCTION

1.1 BACKGROUND OF THE PROJECT

Indian Institute of Technology Madras is one among the foremost institutes of national importance in higher technological education, basic and applied research. In 1956, the German Government offered technical assistance for establishing an institute of higher education in engineering in India. The first Indo-German agreement for the establishment of the Indian Institute of Technology at Madras was signed in Bonn, West Germany in 1959. The Institute was formally inaugurated in 1959 by Prof. Humayun Kabir, then Union Minister for Scientific Research and Cultural Affairs.

Indian Institute of Technology Madras (IITM) is a residential institute with about 605 faculty, 9500 students and 676 administrative and supporting staff. IITM is a self- contained campus located in a beautiful wooded land of about 248 hectares. It has established itself as a premier centre for teaching, research and industrial consultancy in the country and the world.

The Institute has sixteen academic departments and a few advanced research centres in various disciplines of engineering and pure sciences, with nearly 100 laboratories organized in a unique pattern of functioning. Faculty of international repute, brilliant student community, excellent technical and supporting staff and an effective administration have all contributed to the pre-eminent status of IIT Madras. The campus is located in the city of Chennai, previously known as Madras. Chennai is the state capital of Tamil Nadu, a Southern state in India.

IITM has proposed to construct additional academic, residential and hostel buildings to cater to the needs of students, staff and faculty as per the Government of India (GOI) policies pertaining to higher educational institutions.

While augmenting the existing infrastructure, IITM has been taking several initiatives to protect the environment in the campus. The principle of co-existence of human beings and animals without any conflict is practiced in augmenting the infrastructure. As per the Government of India Orders, IITM has been steadily increasing student’s strength besides staff to cater to the needs of our country.

1.2 OBJECTIVES

The key objectives of this study include the following:

To determine the compatibility of the proposed project facilities with the neighboring land uses.

To assess and evaluate the environmental costs and benefits associated with the proposed project.

To evaluate and select the best project alternative from the various options identified.

To incorporate monitoring mechanisms during project implementation and Operational phases.

1.3 ACADEMIC PURSUITS AND THE IIT SYSTEM

IIT Madras was established in 1959 as part of the endeavour by the Government to establish such institutes of national importance across the nation. The primary objective of the IITs in the words of Pandit Jawaharlal Nehru was “To provide scientists and technologists of the highest caliber who would engage in research, design and development to help building the nation towards self reliance in her technological needs”. Five IITs were set up in the period 1951 to 1961 in quick succession – IIT Kharagpur in 1951, IIT Bombay in 1958, IIT Madras in 1959, IIT Kanpur in 1960 and IIT Delhi in 1961. Pursuant to the original goals, these IITs were equipped with full facilities and reached fairly mature states of development very quickly – within a decade in the case of IIT Madras.

The current space needs and requirement to augment facilities and increase in intake are as per the central policy initiatives and directives by the Ministry of Human Resources and Development, Government of India.

1.4 RESIDENTIAL NATURE OF THE INSTITUTE

IITM has always been a residential institute. Most of the faculty, staff and the students reside in the campus. Though there are set timings for the set learning modules, facilities are available round the clock. Institute encourages non-motorized mode of transport inside the campus. Free public transport systems are available in the campus to encourage this. Students in the hostels are prohibited to use motorized vehicles in the campus.

1.5 SUSTAINABILITY: OVERARCHING PRINCIPLES AND THEMES

Planning in the campus takes into account the aspects of sustainability and co- existence of humans and animals. The following points summarize some of the major initiatives:

 The uniqueness of the natural environment and its biodiversity will be the major factor while planning.

 Biodiversity shall not only be protected but also nurtured vigorously.

 Foot print of built environment is recognized as a clear indicator of man’s intervention on the natural environment. Therefore, strategies that restrict further increase shall guide future development and management. Wherever possible, foot print shall not increase; on the contrary planning will aim to decrease this.

 All open spaces and water bodies shall be conserved to the maximum possible extent.

 Planning shall aim to minimize per capita intake of resources from the City’s infrastructure network while at the same time shall also minimize the per capita discharge of waste in to the network.

 All new buildings with a plinth area more than 5000 sq.m in IITM campus are registered for GRIHA 4 rating.

EXPANSION OF IIT MADRAS CHAPTER 2-DESCRIPTION OF THE PROJECT SITE

2.3 SITE CONNECTIVITY

The northern and southern boundaries of the campus front are surrounded by three very busy localities of the city, namely Kotturpuram, Taramani and Velachery. Its neighbors on the northern side are the vast campuses of the CLRI and Anna University all accessed from Sardar Patel Road and green in character thus maintaining a continuity. On the contrary, the southern edge is a rude progression into the dense residential localities of Velachery and Taramani with the south western tip of the academic zone gaining access from the Velachery main road. The campus is the most blessed on the West with its stately, green and completely protected neighbor, the Guindy National Park. The north eastern end of the campus fronts the Film City, with access from the CSIR Road. Its south eastern end is in close proximity to small residential settlements.

The major vehicular entry into the campus is from the north from Sardar Patel Road while there are subsidiary entries on the south west from Velachery main road and south east from the residential area of Taramani. Due to the uniqueness of its composition in being primarily a residential institute, the campus has grown to support several common facilities including schools, banks, post office, temple etc. These facilities that are also open to the neighborhood, draw residents from the surrounds as well, necessitating more than one entry into the campus.

EXPANSION OF IIT MADRAS CHAPTER 2-DESCRIPTION OF THE PROJECT SITE

2.4 TOPOGRAPHY Topographically, the proposed project area is fairly flat terrain. As mentioned, the land slopes from West to East by at least 4 metres. Most of the academic area and some parts of the residential and hostel areas are at a higher elevation while the slopes are felt in the eastern and south eastern segments of the campus that contain hostel and residential zones. Guindy National park itself is at an elevation higher than that of the campus and hence contributes to significant quantity of rain water that ultimately flows through IITM campus into the lake situated in the campus.

2.4.1 Drainage Pattern

A study of the topography of IITM shows that the land slopes to the East, more or less everywhere. Most of the surface run off finds its way to the lake which acts as a natural rainwater harvesting system for the campus. Rain water drainage channels are present mostly in the form of open unlined earthen channels and natural nallas.

3.5 SEWAGE & EFFLUENT GENERATION, TREATMENT AND ITS DISPOSAL

Sewage Treatment Plant

Existing sewer system consists of collecting sewage from individual sources through a series of inspection chambers, connecting the same to the sewer manholes and conveying the sewage to the treatment plant of 4 MLD capacity. Separate network is available for recycling the treated sewage into hostel area for flushing purposes. Excess treated wastewater is disposed to IIT Research Park and to recharge ground water.

3.5.1 Process Description: (SEWAGE PUMPING STATION, SEWAGE TREATMENT PLANT & POST UF TREATMENT):

(a) Sewage Collection and Transfer:

Sewage from the last gravity manhole is extended to a Receiving chamber. The receiving chamber is supplied with aeration air to avoid settling of heavy particles. Sewage from the receiving chamber flows by gravity to the Coarse bar screen chamber. The grit from the mechanical bar screen will be diverted to a hand wheel barrow for disposal to suitable disposal site.

Coarse screened sewage water flows by gravity to the Collection sump. The collection sump is also provided with coarse aeration to avoid settling of solids to the bottom of the tank. The sewage from the collection sump is transferred to Primary Treatment Units through Raw sewage transfer pumps and is metered by a Flow meter.

(b) Primary Treatment Unit:

The purpose of the primary treatment unit is to screen and remove grits in the sewage water. The primary treatment unit consists of a stilling chamber, Fine bar screen chamber, grit chambers and the balancing tank. The sewage water flow from the stilling chamber to the balancing tank is by gravity.

Inlet chamber is the first unit in the Primary treatment unit and receives raw sewage from the raw sewage transfer pumps. The stilling chamber helps in killing the velocity of the pumped sewage and to allow an uniform flow to the Fine bar screen chambers.

The fine screened sewage water flows by gravity to the gravity type grit chambers. The grits from bottom of the grit chambers are manually drained to a standing hand wheel

JANUARY 2019 47

EXPANSION OF IIT MADRAS CHAPTER 3- PROJECT DESCRIPTION

barrow. The screened and grit removed sewage water is transferred by gravity to the next Raw sewage balancing tank through a collection pit.

Homogenization in the Raw Sewage balancing tank is achieved by way of providing coarse bubble aeration (through perforated header – lateral arranged pipe system) at the bottom of the tank. Balancing is achieved by providing sufficient residence time.

The sewage is further transferred to Secondary Treatment unit by the SBR feed pumps with a design flow capacity of 83m3/hr to each pump.

(c) Secondary Treatment Unit:

The secondary treatment step is basically the biological treatment of raw sewage to reduce the BOD and COD contents. Sequential Batch Reactor (SBR) is used for biological treatment. The SBR unit consists of two streams of two batch aeration basins, each designed to treat 50% of raw sewage flow.

The SBR works in batches. The Fill, Aeration, Settling and Decanting forming the four steps in each batch cycle. While one basin in each stream is in filling step, theother basin will be in aeration/ settling/ decanting step. Motorized Isolation gates are provided to stop raw sewage flow to the basin that is not in Fill step. Each basin has an inlet selector zone and an aeration zone. The raw sewage flows through under flow and over flow baffle arrangement in the selector zone prior to flowing into the aeration zone. This effectively provides an anaerobic condition and help in removal of phosphates and denitrification. The selector zone is provided with coarse bubble aeration (perforated tube arrangement). The air flow to the coarse bubble aeration system is as per pre- determined cycle in each batch. The aeration tank is provided with fine bubble diffuser arrangement. Air flow to the fine bubble diffusers is not allowed during the Settling and decanting phase of each cycle.

The decanted treated sewage is divided into two streams (2 X 2 MLD) using motorized valves and Level controller. One stream flows into UF Feed Water storage tank.In ozone contact tank ozone is sparged using diffuser for specified contact time and then drained into the canal .From the UF feed Tank treated sewage is further passed through ultra filtration membranes for reduce the microbial count . The UF permeate is collected in treated water tank in which ozone is sparged for further disinfection and disposal

EXPANSION OF IIT MADRAS CHAPTER 3- PROJECT DESCRIPTION

(d) Tertiary Treatment Unit:

Part of the treated sewage water is transferred to the Tertiary Treatment Unit. The remainder of the treated sewage water is disposed to Buckingham canal by gravity.

The tertiary treatment unit consists of Ultrafiltration membrane units and helps in removal of suspended solids and colloidal solids in the disinfected treated sewage water.The UF units consist of a basket strainer (BS) installed prior to the UF skid and the UF skid (UF). A Flow meter is installed at the inlet of UF skid to read water flow rate into the UF skid. The UF permeate water is collected in UF Permeate water storage tank. The treated water transfer pumps (3 working + 1 stand by) transfers the UF permeate water from UF water storage tank to reuse utility line.

A part of the UF permeate is transferred to UF recovery cleaning tank to facilitate periodical UF back wash. The back wash from UF routed to the nearest storm water drain. The UF membranes are to periodically cleaned with chemicals to remove any scaling or bio fouling. Alkali or acid is used for removal of inorganic scaling and Sodium hypochlorite is used for removal of biological fouling in membranes.

(e) Service Water:

A line is drawn from the discharge of Treated water transfer pumps to provide service water for chemical solution preparation (chemical dosing tanks), water cleaning of bar screens and for water flushing points near chemical dosing area and sludge pump.

(f) Disposal of Treated Sewage/Treatment Plant Sludge

Three lakh litres of treated sewage is used for flushing in hostel and residential zones. A fully-automatic Treated Water Distribution System with 20 km long pipelines connects to every household, hostel and academic block. This enables optimum utilization of treated water. Remaining treated water is stored in the oxidation ponds. Two lakh litres of Excess treated water is disposed to IIT Research park. So, the remaining 10-12 lakh litres is in excess, which is being diverted into ponds and to groundwater recharge. Two groundwater recharge wells are dug up, each having a capacity of 0.5 MLD. This will replenish the fresh water lake. Sludge from the treatment plant is used as manure for gardens in the campus.

3.5.2 Preventive measures to avoid leaching of treated sewage into nearby water courses

Treated sewage from sewage treatment plant will be conveyed to treated sewage tank through pipelines. All the joints from piping system will be checked periodically and carrying treated wastewater pipes will be laid in conduits wherever road crossings are expected. Supervisors will be employed for overall operation and maintenance of water supply, waste water treatment and other utility services.

4.4 FIRE FIGHTING SYSTEM

Fire protection is one of the most essential services to be provided. The principal objective of the rescue and firefighting services is to save lives. For this reason, the provision for means of quick dealing with an accident or incident occurring at, or in the immediate vicinity of, any building, assumes primary importance because it is within this area that there is the greatest opportunity of saving lives. This must assume at all times the possibility of, and need for, extinguishing a fire which may occur either immediately following an accident or incident, or at any time during rescue operations. In the design component of the project, adequate measure is being taken as per the provisions of the National Building Code, 2005. The fire fighting system will comprise the following. Fire hydrant system The buildings will be provided with adequate nos. of external and internal fire hydrants with fire hose cabinet. Portable fire extinguishers Selection, installation and maintained of first aid extinguishers will be done as per lS: 2190 - 1992 and among different types of portable fire extinguishers generally followed types will be provided. Water fire extinguishers Two extinguishers per compartment/floor of building will be provided and firefighting sump will be installed for water storage.
