in NMT modes (reduction in walking by 2%, cycling
by 11%) and public transport (by 13%) between
1992-95 to 2008 due to lack of adequate
infrastructure. (Source: CCTS 2008) •

cars have increased by 5%, two-wheelers by 18%
from 1992-95 to 2008. (Source: CCTS 2008) • Road

TA M I L N A D U
The city of Chennai is the birthplace of the railway system in India. In 1831-33, Madras
Parliament first came up with the idea. In 1832, the first proposal of railway under the
British administration was made in Madras.

13. STORM
WATER
• • Flooding or water logging in
streets and subways during heavy
rains due to flat terrain
Storm
water
• Solid waste management with limited source
Prevalence of open storage at primary bins - Shops,
households and commercial establishments continue to
dump the waste in compactor bins •
• Minimal recycling & lack of adequate processing
like RDF plants/ composting units. Capacity constraint in
the existing dump yards
Solid waste

14. WASTE DISPOSAL
• Waste Disposal
At present Garbage generated in Chennai is dumping at
two land fill sites and construction and demolition waste
being used for covering each layer of garbage in two
dump sites.
For remediation of the existing Landfill or scientific
closure and to have the Integrated waste processing
facilities with waste to energy plant as component at the
existing Kodungaiyur and Perungudi dump sites, the
Transaction Advisory Consultant have prepared DFR and
sent for approval of the competent Authority and
simultaneously the RFP documents are under
preparation.

15. WASTE DISPOSAL

16. WASTE DISPOSAL
Collection of Solid Waste at Source
Collection of Municipal Solid Waste at source (Door to door collection) has been
implemented in all Zones. About 95% of the households were covered under this programme.
This has been achieved only on introduction of Tricycles which stands as a wonder tool
for better collection of MSW at door steps. Now about 5400 Tricycles are in use for reduction
of dust bins on road side.
Source Collection
Source separation is promoted to reduce the waste coming to the Landfill, thereby
increasing the life time of the Landfills.
The bio-degradable waste (Organic Waste) is being composted in a decentralized
manner at ward level by Ordinary and Vermi compost plants and Bio methanation plants and
manure used for GCC parks and greeneries besides open sale to public also.
Source separated thin plastics are subjected to shredding in all units / zones and it has
been used for laying Bituminous road laying. The source Separated non biodegradable (Dry
Waste) collected on every Wednesdays for recycling.

17. WAT E R S U P P LY I N
C H E N N A I
The Chennai urban population was
about 5.92 million and the city
population was about 4.03 million
in the year 1991 and it is estimated
that by the turn ofthis century,
Chennai city will have more than 4.5
million people. Chennai is the
principal port on the Coromandel
coast of Southern India. The
Chennai area has good potential for
industrial growth with relatively
better infrastructure facilities like
transport, electric power supply etc.
except drinking water. The areal
extent ofChennai city is 175.03 km2
and that ofthe Chennai
Metropolitan area is 1,170 km2.
Most parts of the city are within 4 to
5 metres above mean sea level.

18. WATER SUPPLY

19. CHENNAI WATER SUPPLY
 Chennai is entirely dependent on ground water resources to meet its water needs.
 Ground water resources in Chennai are replenished by rain water and the city's average
rainfall is 1,276 mm.
 Chennai receives about 985 million liters per day (mld) from various sources against the
required amount of 1,200 mld.
 This demand is expected to rise to 2,100 mld by 2031.
 Water to the city's residents is being supplied from desalination plants at Nemelli and
Minjur; aquifers in Neyveli, Minjur and Panchetty;
 Cauvery water from Veeranam lake;
 Krishna river from Andhra Pradesh;
 Poondi reservoir; and lakes at Red Hills, Chembarambakkam and Sholavaram
 There are four reservoirs in the city, namely, Red Hills, Cholavaram, Poondi and
Chembarambakkam, with a combined capacity of 11,057 mcft.
 The Red Hills reservoir has a capacity of 3,300 mcft. The Cholavaram reservoir has a
capacity of 881 mcft. The Poondi reservoir has a capacity of 3,231 mcft. The
Chembarambakkam reservoir has a capacity of 3,645 mcft. The reservoirs lose 5 mcft daily
due to evaporation.[11] A fifth reservoir is being planned

20. WATER SUPPLY

21. WATER ISSUES
At present the Chembarambakkam reservoir has been
used fully for irrigation.
There is a proposal to buy the irrigation rights and convert
it as a fully drinking water supply reservoir.
The reservoir has about 5400 ha of registered command
area in 38 villages.
Nearly 50 per cent ofthe command area is not getting
water through irrigation canals due to poor maintenance
ofirrigation canals and the farmers are using groundwater
from local wells.
Rapid urbanisation in this area also reduces the water
requirement for irrigation purposes.
