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.

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.

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.

Current effluent treatment
Almost 12 different processes in dyeing release effluents
Dyeing industries introduced a treatment process, to
remove the dye color from water.

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.

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.

Continued....
Reverse osmosis takes place in
the tertiary treatment. These treated effluents can be
reused by dyeing industries.

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.

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

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.

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.

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.

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.

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

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.
