Opportunities India’s Urbanization to 2030…

68 cities – will have population of 1 million plus, up from 42 today.

$ 1.2 trillion capital investment is necessary to meet projected demand in India’s cities.

700 – 900 million square meters of commercial & residential space needs to be built..

2.5 Billion square meters of roads will have to be paved

7400 kms of metros and subways will need to be constructed.

India’s Urbanization Critical issues...

“we are like this only”Inadequate Housing

Inadequate Transport systems…

Poor Local Governance

Weak Finances Unplanned expansion within cities

Critical Infrastructure shortage

Rapidly deteriorating environment...

India’s Urbanization 2030What we must do ?

• Creation of well planned - New Satellite Cities around big cities (ex Delhi-Noida, F’bad, Gurgaon, Dwaraka)

• Planned zones/ sectors – self contained with water/ sewage, garbage, etc

• Built by side of express highway with arterial roads, metros, etc linked to main city.

• Cities to be planned with elite to affordable & mass housing with societal interests taken care off

• Must for success is Public Transportation/ Schooling/ Water/ Sewage & Garbage processing

- Elevated Roads/ Express Highways/ Rail Corridors/ Mass Rapid Transit systems

• Emphasis on climate friendly technologies.

CHENNAI- URBAN INFRASTRUCTUREPLANNING & DEVELOPMENT

Chennai City Growth1923 2026

Chennai’s urban population would be11 millionby 2030

Chennai - Urban Infrastructure Development

• Infrastructure development is the key initiative to improve the economy

• Key sectors to focus..– Transportation & Parking – Water supply– Sanitation– Power– Health, Education & Entertainment– Affordable Housing

Chennai - Transportation & Parking• Immediate requirements

– Cleaning of roads & clearing encroachments– Traffic regulation / management– Subways & foot over bridge– Flyovers at critical junctions

• Long-term requirements– Metros– Mono rail– Elevated road corridors– Multilevel car parking– Airports

Chennai - Water Supply• Immediate requirements

– Increase in the quality, quantity & coverage of supply

– Restoration of water reservoirs• Long-term requirements

– Water recharging systems– Improved Water management – Desalination Plants – Linking of rivers– Recycling of water

Chennai - Sanitation• Immediate requirements

– Sanitation awareness– Construction of public toilets– Effective storm water management– Collection & recycling of waste

• Long-term requirements– Cleaning of existing sewers, coovam, adyar– Underground sewer network– Sewer treatment plants (at basin level)

Chennai - Power• Immediate requirements

– Provide uninterrupted power supply– Insist for the use of solar energy – Arrest power losses

• Long-term requirements– Drive Nonconventional energy production like

Nuclear power / Solar / wind power plants– Create utility service corridors

Suggestions for Implementation

• Create a nodal department / institution for each area

• The nodal department is accountable for implementation of all facilities and governed by four parameters while implementation i.e Time, Quality, Safety & Inconvenience to public / citizen.

• Attract the corporates / companies with tax benefits for implementation area-wise / key sector-wise

Divide in to Zones

Smart Cities in the World..

Smart Cities..

A mix of well planned Land spaces comprising of Commercial, Residential, & Social facilities with well planned Infrastructure while maintaining ecological through.

New Trends in Smart Cities..

• High Rise Construction

• Green Buildings

• Solid Waste Management

• District Cooling Systems

• Home Automation

• Renewable Energy

New Trends – High Rise

High Rise – Mix of Uses

What is “Green”?

Energy Efficiency & Eco-friendly

Use of Renewable Energy

Water Efficiency

Use of Recycled/Recyclable Products

Design and construct facilities that

Minimize adverse effects on the exterior environment

Enhance the quality of the indoor environment

Minimize consumption of Resources1. Energy 2. Water3. Construction materials &4. other resources both initially and on a life cycle basis.

Solid Waste Management Urbanization - contributing to waste generation

No trend available in India

Waste collected through suction / air velocity

Waste Treatment through Technology

District Cooling System

• Efficiency through economies of scale

• Reduces energy costs up to 30%

• Reduce maintenance costs

• Improves air quality & temperature control.

Home Automation

• Security

• Convenience

• Energy Savings

Investing in the Future of Energy - Solar Power

PURPOSE/ OBJECTIVE :

• “Green Power”- contribute towards the preservation of Mother Earth’s resources

• Need for a reliable Back up power for meeting emergency needs.

• To reduce dependency on DG set and diesel oil.Solar Power – Installed in L&T- ECC Manapakkam, Chennai office
