Textile Dyeing Unit Pollution: Legal Remedies

If a textile dyeing, printing or jeans washing unit is letting coloured water into a drain, a field or the ground near you, the State Pollution Control Board can inspect it, sample its effluent and order it closed under section 33A of the Water Act. If the unit is running in a residential colony or village abadi, the municipal body or development authority can also seal it for breaking land-use rules. Dyeing units use a great deal of water and salt, so groundwater extraction and soil damage often come into the case too. When the authorities do nothing, the NGT can step in. Dyeing unit owners, for their part, have a clear set of obligations that, if met, keep these remedies away from their door.

This guide covers why dyeing effluent is treated so seriously, the kinds of dyeing units that cause complaints, the remedies available to residents and farmers, the authorities responsible for each part of the problem, and what dyeing unit owners must have in place. It ends with a made-up example, a checklist and common questions.

For the general law on factory effluent, see our page on industrial effluent and water pollution remedies. For how to word the complaint itself, read how to complain about untreated industrial effluent.

The essentials

A dyeing unit near us is releasing coloured water. What can we do?

Start with a written complaint to the regional office of your State Pollution Control Board, or the DPCC if you are in Delhi. Name the unit, describe the colour and smell, say where the water goes and when, attach dated photos, and ask for an inspection, sampling at the outlet and in the drain, and action under section 33A of the Water Act. Dyeing effluent is one of the easier kinds to photograph, because the colour is unmistakable. Use that.

Then look at where the unit is. A large processing house in an industrial area is mainly the pollution board's concern. A small dyeing or jeans washing unit in a residential colony, an urban village or a farmhouse plot is usually committing a second wrong as well: running an industry where the master plan or zoning does not allow it. That is for the municipal corporation or development authority, which can seal premises used against permitted land use. Complain to both. They act under different laws and neither needs to wait for the other.

If written complaints and reminders over a few months bring no lasting result, the NGT can hear the matter. Dyeing effluent raises a substantial environmental question under the Water Act, and the tribunal commonly asks a joint committee of the board, the CPCB and the District Magistrate to inspect and report.

Why dyeing effluent does so much damage

The colour is what people notice, and it is a real problem: coloured water blocks light, harms aquatic life, and some dyes and their breakdown products are toxic. But the more lasting damage comes from things you cannot see. Dyeing, especially of cotton with reactive dyes, uses large amounts of common salt or sodium sulphate to fix the dye. Most of that salt ends up in the effluent. Salty water in a canal or a field makes the soil saline and hard to farm, and salt that seeps into the ground raises the dissolved solids in handpumps and borewells for years.

Add to that the alkalis used in scouring and mercerising, bleaching chemicals, sulphides from sulphur dyes, softeners and other auxiliaries, and the heat of process water. Jeans washing units add indigo, enzymes and, in older setups, pumice stone sludge that clogs drains. Printing units use pastes and binders that carry heavy organic load. The result is effluent that a simple settling tank does nothing for.

This is why dyeing units are usually required to treat effluent fully, send it to a CETP built for the purpose, or meet zero liquid discharge, depending on the state and cluster. Our guide on zero liquid discharge rules explains when ZLD applies.

Different dyeing units, different problems

The laws that apply to dyeing units

Steps for residents and farmers

These steps suit both a colony troubled by a small unit and a village downstream of a cluster.

Illegal dyeing units in residential colonies and villages

These are the cases that make residents angriest, and they are often the easiest to win on paper. A dyeing or jeans washing unit in a house or a small plot in a residential colony usually has no consent from the pollution board, because boards generally do not grant consent to such units in residential areas. It is also using the premises against the master plan. And it is often drawing groundwater through a borewell and running on a domestic or non-industrial electricity connection.

Each of those is a separate lever. The pollution board can direct closure and disconnection for running without consent and discharging effluent. The municipal body or development authority can seal the premises for misuse. The groundwater authority can act on unauthorised extraction. And the electricity distribution company can act on misuse of the connection. Our guide on illegal change of land use causing pollution covers the land-use side in more detail.

The difficulty is that such units close and reopen. A sealed unit moves to the next lane, or the seal is broken a few weeks later. Residents need to keep watching and report reopening promptly, quoting the earlier sealing or closure order. Breaking a seal is a separate offence, and a unit that reopens after closure is treated far more harshly. Advocate B.K. Singh's advice to RWAs fighting these units is to keep a single file with every complaint, every sealing order and every photograph in date order, because when the matter reaches the NGT, that file is the case.

Pollution from dyeing clusters and CETPs

In well-known textile processing centres such as Tiruppur, Surat, Ludhiana, Panipat and Pali, dyeing units often operate in clusters served by common effluent treatment plants. The complaint then has two possible targets: an individual unit that bypasses the CETP or sends effluent above its inlet norms, and the CETP itself, if its outlet does not meet standards or it is overloaded.

For villages downstream of a cluster, it helps to ask the board for samples at the CETP outlet, at the point where the drain carrying it meets the river or channel, and at points upstream. If the CETP outlet is within norms but the drain is not, the problem is units bypassing the CETP. If the CETP outlet itself fails, the operator and its member units are answerable together. Our guide on CETP compliance explains how responsibility is shared.

In clusters with a long history of pollution, the board or the tribunal may have issued area-wide directions, such as a ZLD requirement or a moratorium on new units. Ask about these in your RTI, because they change what any unit in the cluster is allowed to do.

What a dyeing unit must have in place

Dyeing and processing units are generally placed in the most polluting category under the CPCB's red, orange, green and white scheme, which means stricter consent conditions and more frequent inspection. Our page on industry categories explains the scheme, and consent to operate covers the permission itself.

Our dyeing unit has a sealing or closure notice. What now?

Check which authority issued it and under which law, because the answer is different for each. A pollution board show-cause notice under section 33A needs a reply on the facts of your effluent treatment and consent. A municipal or development authority notice about land use needs a reply on whether industrial use is permitted at your address. If the honest answer is that it is not, no amount of effluent treatment will save the location, and the practical question becomes relocation to a permitted area with a time-bound plan.

For a unit in a proper industrial area, the usual path is to show compliance: the ETP or CETP connection working, sludge and salt going to an authorised facility, consent valid, and outlet tests within norms. Boards revoke closure on proof of compliance, often with a bank guarantee. If the direction is unjustified, an appeal to the NGT under section 33B lies within 30 days. Our page on replying to a closure notice explains the process.

Do not try to carry on quietly after a closure direction or a seal. Reopening without permission is the fastest way to turn a curable problem into a prosecution and a much heavier environmental compensation order.

Compensation for damaged fields and water

Farmers whose land has been made saline or whose crops have failed because of dyeing effluent can claim compensation and restoration under section 15 of the NGT Act within 5 years of the cause of action. The NGT applies the polluter pays principle, which covers the cost of restoring the damaged environment as well as compensating victims.

The evidence that matters is a before-and-after picture: past yields, the agricultural officer's report on crop damage, soil and water test results showing salinity or colour, and a link to the unit or cluster through samples upstream and downstream. Where groundwater is affected, our guide on proving groundwater contamination from industry explains what to collect. Health claims are possible but harder to prove, and need medical evidence.

Mistakes on both sides

Residents often complain about 'pollution in the area' instead of naming units, and the board inspects the area, finds nothing it can pin on anyone, and closes the file. They also rely on the colour alone and do not ask for samples, though the salts and chemicals are what prove lasting harm. And they stop after the first sealing, when reopening is the norm, not the exception.

Unit owners make a different set of mistakes. They set up in a residential or non-conforming area because rent is cheaper, then invest in treatment that cannot cure the location problem. They treat sludge and salt as ordinary waste and dump it on vacant land, creating a separate violation. They draw groundwater without a NOC. And they expand production without telling the board, so the ETP falls behind and the next inspection finds a breach. Each of these is avoidable, and each is far cheaper to fix before a complaint than after.

When to go to the NGT, and when not to

The NGT is worth it when the board and the land-use authority have been told in writing and have failed to stop the discharge, when a cluster or CETP is affecting several villages, or when land and water have been damaged and compensation and restoration are needed. The tribunal's joint committee inspections often get past the local pressures that keep a regional office from acting.

It is not the right first step for a single small unit that nobody has yet complained about. A well-drafted complaint to the board and the municipal body will often close such a unit within weeks, and an NGT application filed before that would probably be sent back to them anyway. If you are unsure which stage you are at, our page on pollution complaints explains how we approach the early stage, and NGT case filing covers the tribunal.
