TirupurA STUDY ON ITS ENVIRONMENTAL DEGRADATION

The Tirupur Story

India is one of the largest textile exporters in the world

Introduction of New economic policy and removal of quota systemhas further fuelled the growth of exports over the years.

Tirupur, Tamil Nadu is one of the largest contributor to Indias textileoutput, and has 4,000 units in this business

It thus, contributes a significant part of Indias foreign exchange But this increasing commercialization has taken a toll on its

environment.

It is facing a severe shortage of potable water and infrastructure.


3/18

Environmental Degradation

Dyeing and bleaching units, mostly primitive, are pumping out largquantities of effluents.

The ground water, soil and water bodies, as a result have degradedup to a large extend

700 dyeing units discharge 100 million liters of untreated effluenteveryday.

As a result, sludge has accumulated largely in Noyyal, a tributary oCauvery.

Moreover, 20,000 acres of land downstream has been renderedunfit for cultivation.


4/18

Dyeing Industry- bearing the burn

The dyeing units are creating many problems due to environmenta

pollution, and Madras High court has approached activists to

propose a lasting solution.

Court has ordered these units to shut down, unless they add RO

system to treat their discharge.


5/18

Current effluent treatment

Almost 12 different processes in dyeing release effluents

Dyeing industries introduced a treatment process, to

remove the dye color from water.


6/18

Solar Pond and primary treatmentplant.

A 1000 metre square pond, is used to evaporate high salt content

water, and the left over sludge is disposed off.

The left over processes have less content of salt, and are treated

using primary treatment plant, using various chemicals

As a result treated water is achieved, containing only biological

waste, which still contaminate ground water.


7/18

REVERSE OSMOSIS

Govt of Tamil Nadu made it

compulsory for Dyeing units to putthe plant.

Process:

Primary treated effluent passesthrough secondary treatment inwhich effluent is treated with

bacteria. Bacteria removes the biological

matter

The secondary effluent undergoestertiary treatment.


8/18

Continued....

Reverse osmosis takes place in

the tertiary treatment. These treated effluents can be

reused by dyeing industries.


9/18

River Noyyal

Source of water for many places along

Tirupur. Tirupur - Once an Agrarian village and

farmers depended on the water forirrigation.

Industrialization into textile town lead toenvironmental pollution.


10/18

People were ignorant of the ill effects and others neglected theconsequences.

Measures were not taken.

River is totally contaminated and has become a dumping ground.

Flora and fauna are in danger.

Effluents have depleted agricultural land and contaminated theground water


11/18

ORATHUPALAYAM DAM

Built on River Noyyal

Dimension: 2290m (L) x 248m (W).

Area: 423 Hectares.

Irrigates 9875 acres of agricultural land in Karur district and 500 acreof land in Erode district.

Max Outflow90,900 cubic feet.


12/18

Contaminated water from effluents also gets stored in the dam.

Problem of dam overflowing.

Severe pollution problem.

Government expresses concern and tightens effluent treatmentrequirement.


13/18

Affected group

Well water(open n closed)

Change in water colour

Water borne disease

Land impacted

Low yield

Fishes

Fishes died and contamination in aquaticlife.

Animals

Residents-smell and health problems.

Dam got eroded.


14/18

IMPACT ON DYEING INDUSTRY

Proper pollution control measures

Around 600 industries shut down due to court order, which createda supply chain imbalance.

To avoid consequences industry promised to set up RO plants infew months time.

Investments- 10 to 20 million cost for single RO plant, which is a veryhigh cost.


15/18

PRESENT SCENARIO

Only few industries set-up plant.

To ensure consistency govt.Makes surprise visits.

20 CETP ( common effluenttreatment plants) were set up,covering 437 companies.

92 bleaching units were setup

and 152 individual treatmentplants costing 2000 million.


16/18

Turn over INR30000 million.

New textile township, Nethaji Apparel Park, as a result exports willtouch INR100000 million.

Wal-Mart buys textile costing $ 5 billion in this region.

PRESENT SCENARIO


17/18

PROPOSED SOLUTION

Subsidies should be given for initial set-up.

Import of dyed clothes from china should be discouraged.

Govt. Should accelerate their actions to avoid cases like Sirumugaiin Coimbatore and Ambur.

Govt. should commercialize environment protection sector byencouraging private players to enter the sector.
