Full Case Details

– This is a public interest litigation. The petitioner who is
an active social worker has filed this petition inter alia for the issue of a writ/order/direction
in the nature of mandamus to the respondents other than Respondents 1 and 7 to 9 restraining
them from letting out the trade effluents into the river Ganga till such time they put up
necessary treatment plants for treating the trade effluents in order to arrest the pollution of
water in the said river. Respondent 1 is the Union of India, Respondent 7 is the Chairman of
the Central Board for Prevention and Control of Pollution, Respondent 8 is the Chairman,
Uttar Pradesh Pollution Control Board and Respondent 9 is the Indian Standards Institute.

  1. Water is the most important of the elements of nature. River valleys are the cradles of
    civilization from the beginning of the world. Aryan civilization grew around the towns and
    villages on the banks of the river Ganga. Varanasi which is one of the cities on the banks of
    the river Ganga is considered to be one of the oldest human settlements in the world. It is the
    popular belief that the river Ganga is the purifier of all but we are now led to the situation that
    action has to be taken to prevent the pollution of the water of the river Ganga since we have
    reached a stage that any further pollution of the river water is likely to lead to a catastrophe.
    There are today large towns inhabited by millions of people on the banks of the river Ganga.
    There are also large industries on its banks. Sewage of the towns and cities on the banks of
    the river and the trade effluents of the factories and other industries are continuously being
    discharged into the river. It is the complaint of the petitioner that neither the Government nor
    the people are giving adequate attention to stop the pollution of the river Ganga. Steps have,
    therefore, to be taken for the purpose of protecting the cleanliness of the stream in the river
    Ganga, which is in fact the life sustainer of a large part of the northern India.
  2. When this petition came up for preliminary hearing, the Court directed the issue of
    notice under O. 1, R. 8 of the Code of Civil Procedure treating this case as a representative
    action by publishing the gist of the petition in the newspapers in circulation in northern India
    and calling upon all the industrialists and the municipal corporations and the town municipal
    councils having jurisdiction over the areas through which the river Ganga flows to appear
    before the Court and to show cause as to why directions should not be issued to them as
    prayed by the petitioner asking them not to allow the trade effluents and the sewage into the
    river Ganga without appropriately treating them before discharging them into the river.
    Pursuant to the said notice a large number of industrialists and local bodies have entered
    appearance before the Court. Some of them have filed counter-affidavits explaining the steps
    taken by them for treating the trade effluents before discharging them into the river.

  3. Before proceeding to consider the facts of this case it is necessary to state a few words
    about the importance of and need for protecting our environment. Article 48-A of the
    Constitution provides that the State shall endeavour to protect and improve the environment
    and to safeguard the forests and wild life of the country. Article 51-A of the Constitution
    imposes as one of the fundamental duties on every citizen the duty to protect and improve the
    natural environment including forests, lakes, rivers and wild life and to have compassion for
    living creatures. The proclamation adopted by the United Nations Conference on the Human
    Environment which took place at Stockholm from 5th to 16th of June, 1972 and in which the
    Indian delegation led by the Prime Minister of India took a leading role runs thus:
  4. Man is both creature and moulder of his environment which gives him
    physical sustenance and affords him the opportunity for intellectual, moral, social and
    spiritual growth. In the long and tortuous evolution of the human race on this plannet
    a stage has been reached when through the rapid acceleration of science and
    technology, man has acquired the power, to transform his environment in countless
    ways and on an unprecedented scale. Both aspects of man’s environment, the natural
    and the man made, are essential to his well being and to the enjoyment of basic
    human rights – Even the right to life itself.
  5. The protection and improvement of the human environment is a major issue
    which affects the well-being of peoples and economic development throughout the
    world, it is the urgent desire of the peoples of the whole world and the duty of all
    Governments.
  6. Man has constantly to sum up experience and go on discovering, inventing,
    creating and advancing. In our time man’s capability to transform his surroundings,
    if used wisely, can bring to all peoples the benefits of development and the
    opportunity to enhance the quality of life. Wrongly or heedlessly applied, the same
    power can do incalculable harm to human beings and the human environment. We
    see around us growing evidence of man-made harm in many regions of the earth;
    dangerous levels of pollution in water, air, earth and living beings; major and
    undesirable disturbances to the ecological balance of the biosphere; destruction and
    depletion of irreplaceable resources; and gross deficiencies harmful to the physical,
    mental and social health of man, in the man-made environment; particularly in the
    living and working environment.
    A point has been reached in history when we must shape our actions throughout
    the world with a more prudent care for their environmental consequences. Through
    ignorance or indifference we can do massive and irreversible harm to the earthly
    environment on which our life and well-being depend. Conversely, through fuller
    knowledge and wiser action, we can achieve for ourselves and our posterity a better
    life in an environment more in keeping with human needs and hopes. There are
    broad vistas for the enhancement of environmental quality and the creation of a good
    life. What is needed is an enthusiastic but calm state of mind and intense but orderly
    work. For the purpose of attaining freedom in the world of nature man must use
    knowledge to build in collaboration with nature a better environment. To defend and
    improve the human environment for present and future generations has become an
    151
    imperative goal for mankind, a goal to be pursued together with, and in harmony
    with, the established and fundamental goals of peace and of world-wide economic
    and social development.
    To achieve this environmental goal will demand the acceptance of responsibility
    by citizens and communities and by enterprises and institutions at every level, all
    sharing equitably in common efforts. Individuals in all walks of life as well as
    organizations in many fields, by their values and the sum of their actions, will shape
    the world environment of the future. Local and National Governments will bear the
    greatest burden for large-scale environmental policy and action within their
    jurisdictions. International co-operation is also needed in order to raise resources to
    support the developing countries carrying out their responsibilities in this field. A
    growing class of environmental problems, because they are regional or global in
    extent or because they affect the common international realm, will require extensive
    co-operation among nations and action by international organizations in the common
    interest. The Conference calls upon the Governments and peoples to exert common
    efforts for the preservation and improvement of the human environment, for the
    benefit of all the people and for their posterity.
    The proclamation also contained certain common convictions of the participant nations
    and made certain recommendations on development and environment. The common
    convictions stated include the conviction that the discharge of toxic substances or of other
    substances and the release of heat in such quantities or concentrations as to exceed the
    capacity of environment to render them harmless must be halted in order to ensure that
    serious or irreversible damage is not inflicted upon eco systems, that States shall take all
    possible steps to prevent pollution of the seas so that hazards to human health, harm to living
    resources and marine life, damage to the amenities or interference with other legitimate uses
    of seas is avoided, that the environmental policies would enhance and not adversely affect the
    present and future development potential of developing countries, that science and technology
    as part of their contributions to economic and social development must be applied with
    identification, avoidance and control of environmental risks and the solution of environmental
    problems and for the common good of mankind, that States have the responsibility to ensure
    that activities of exploitation of their own resources within their jurisdiction are controlled
    and do not cause damage to the environment of other States or areas beyond the limit of
    national jurisdiction, that it will be essential in all cases to consider the system of values
    prevailing in each country and the extent of the applicability of standards which are valid for
    the most advanced countries but which may be inappropriate and of unwarranted social cost
    and that man and his environment must be spared the effects of nuclear weapons and all other
    means of mass destruction. These are only some of the statements of principles proclaimed
    by the Stockholm Conference.
  7. Realising the importance of the prevention and control of pollution of water for human
    existence Parliament has passed the Water (Prevention and Control of Pollution) Act, 1974
    (‘the Act’) to provide for the prevention and control of water pollution and the maintaining or
    restoring of wholesomeness of water, for the establishment, with a view to carrying out the
    purposes aforesaid, of Boards for the prevention and control of water pollution for conferring
    152
    on and assigning to such Boards powers and functions relating thereto and for matters
    concerned therewith. The Act was passed pursuant to resolutions passed by all the Houses of
    Legislatures of the States of Assam, Bihar, Gujarat, Haryana, Himachal Pradesh, Jammu and
    Kashmir, Karnataka, Kerala, Madhya Pradesh, Rajasthan, Tripura and West Bengal under Cl.
    (1) of Art. 252 of the Constitution to the effect that the prevention and control of water
    pollution should be regulated in those States by Parliamentary legislation. The Act has been
    since adopted by the State of Uttar Pradesh also by resolutions passed in that behalf by the
    Houses of Legislature of the said State in the year 1975 (vide notification No. 897/IX-3-100-
    74 dated 3-2-1975). Section 24 of the Act prohibits the use of any stream or well for disposal
    of polluting matter etc. It provides that subject to the provisions of the said poisonous,
    noxious or polluting matter determined in accordance with such standards as may be laid
    down by the State Board to enter whether directly or indirectly into any stream or well or no
    person shall knowingly cause or permit to enter into any stream any other matter which may
    tend either directly or in combination with similar matters to impede the proper flow of the
    water of the stream in a manner leading or likely to lead to a substantial aggravation of
    pollution due to other causes or of its own consequences. The expression stream is defined by
    S. 2(j) of the Act as including river, water course whether flowing or for the time being dry,
    inland water whether natural or artificial, sub-terranean waters, sea or tidal waters to such
    extent or as the case may be to such point as the State Government may by notification in the
    Official Gazette, specify in that behalf. Under the Act it is permissible to establish a Central
    Board and the State Boards. The functions of the Central Board and the State Boards are
    described in Ss.16 and 17 respectively. One of the functions of the State Board is to inspect
    sewage or trade effluents, works and plants for the treatment of sewage and trade effluents
    and to review plans, specifications or other data relating to plants set up for the treatment of
    water, works for the purification and the system for the disposal of sewage or trade effluents.
    ‘Trade effluent’ includes any liquid, gaseous or solid substance which is discharged from any
    premises used for carrying on any trade or industry, other than domestic sewage. The State
    Board is also entrusted with the work of laying down standards of treatment of sewage and
    trade effluents to be discharged into any particular stream taking into account the minimum
    fair weather dilution available in that stream and the tolerance limits of pollution permissible
    in the water of the stream, after the discharge of such effluents. The State Board is also
    entrusted with the power of making application to courts for restraining apprehended
    pollution of water in streams or well. Notwithstanding the comprehensive provisions
    contained in the Act no effective steps appear to have been taken by the State Board so far to
    prevent the discharge of effluents of the Jajmau near Kanpur to the river Ganga. The fact that
    such effluents are being first discharged into the municipal sewerage does not absolve the
    tanneries from being proceeded against under the provisions of the law in force since
    ultimately the effluents reach the river Ganga from the sewerage system of the municipality.
  8. In addition to the above Act, Parliament has also passed the Environment (Protection)
    Act, 1986 which has been brought into force throughout India with effect from November 19,
  9. Section 3 of this Act confers power on the Central Government to take all such
    measures as it deems necessary or expedient for the purpose of protecting and improving the
    quality of the environment and preventing, controlling and abating environmental pollution.
    ‘Environment’ includes water, air and land and the inter-relationship which exists among and
    153
    between water, air and land and human beings, other living creatures, plants, micro-organisms
    and property. (S. 2(a) of the Environment (Protection) Act, 1986). Under S. 3(2)(iv) of the
    said Act the Central Government may lay down standards for emission or discharge of
    environmental pollutants from various sources whatsoever. Notwithstanding anything
    contained in any other law but subject to the provisions of the Environment (Protection) Act,
    1986, the Central Government may under S. 5 of the Act, in the exercise of its powers and
    performance of its functions under that Act issue directions in writing to any person, officer or
    authority and such authority is bound to comply with such directions. The power to issue
    directions under the said section includes the power to direct the closure, prohibition or
    regulation of any industry, operation or process or stoppage or regulation of the supply of
    electricity or water or any other service. Section 9 of the said Act imposes a duty on every
    person to take steps to prevent or mitigate the environmental pollution. Section 15 of the said
    Act contains provisions relating to penalties that may be imposed for the contravention of any
    of the provisions of the said Act or directions issued thereunder. It is to be noticed that not
    much has been done even under this Act by the Central Government to stop the grave public
    nuisance caused by the tanneries at Jajmau, Kanpur.
  10. All the tanneries at Jajmau, Kanpur which were represented by counsel, except
    respondents Nos. 87 and 89 have relied upon a common counter-affidavit filed by them and
    their case is argued by Shri S.K. Dholakia and Shri Mukul Mudgal. Respondent No. 87 is
    represented by Shri R.P. Gupta and respondent No. 89 is represented by Shri P. Narasimhan.
    There is not much dispute on the question that the discharge of the trade effluents from these
    tanneries into the river Ganga has been causing considerable damage to the life of the people
    who use the water of the river Ganga and also to the aquatic life in the river. The tanneries at
    Jajmau in Kanpur have themselves formed an association called Jajmau Tanners Pollution
    Control Association with the objects among others:
    (1) To establish, equip and maintain laboratories, workshop, institutes, organisations
    and factories for conducting and carrying on experiments and to provide funds for the
    main objects of the Company.
    (2) To procure and import wherever necessary the chemicals etc. for the purpose of
    pollution control in tanning industries.
    (3) To set up and maintain common effluent treatment plant for member tanners in
    and around Jajmau.
    (4) To make periodical charges on members for the effluent treatment based on the
    benefit he/it derives from time to time to meet the common expenses for maintenance,
    replacement incurred towards effluent treatment.
  11. There is a reference to the Jajmau tanneries in ‘an Action Plan for Prevention of
    Pollution of the Ganga’ prepared by the Department of Environment, Government of
    India in the year 1985, which is as under: –
    1.1 The Ganga drains eight States: Himachal Pradesh, Punjab, Haryana, Uttar
    Pradesh, Rajasthan, Madhya Pradesh, Bihar, West Bengal and the Union Territory of
    Delhi. It is also the most important river of India and has served as the cradle of
    Indian Civilization. Several major pilgrim centres have existed on its banks for
    centuries and millions of people come to bathe in the river during religious festivals,
    154
    especially the Kumbhas of Haridwar and Allahabad. Many towns on the Ganga, e.g.
    Kanpur, Allahabad, Patna and Calcutta have very large populations and the river also
    serves as the source of water supply for these towns. The Ganga is, however, being
    grossly polluted especially near the towns situated on its banks. Urgent steps need to
    be taken to prevent the pollution and restore the purity of river water.
    2.0 Sources of Pollution
    2.1 The main sources of pollution of the Ganga are the following:-
    Urban liquid waste (Sewage, storm drainage mixed with sewage, human, cattle
    and kitchen wastes carried by drains etc.)
    Industrial liquid waste
    Surface run-off of cultivated land where cultivators use chemical fertilisers,
    pesticides, insecticides an such manures the mixing of which may make the river
    water unsafe for drinking and bathing.
    Surface turn-off from areas on which urban solid wastes are dumped.
    Surface run-off from areas on which industrial solid wastes are dumped.
    4.4.12 Effluent from industries:
    Under the laws of the land the responsibility for treatment of the industrial
    effluents is that of the industry. While the concept of ‘Strict Liability’ should be
    adhered to in some cases, circumstances may require that plans for sewerage and
    treatment systems should consider industrial effluents as well. Clusters of small
    industries located in a contiguous area near the river bank and causing direct
    pollution to the river such as the tanneries in Jajmau in Kanpur is a case in point. In
    some cases, waste waters from some industrial units may have already been
    connected to the city sewer and, therefore, merit treatment along with the sewage in
    the sewage treatment plant. It may also be necessary in some crowded areas to
    accept waste waters of industries in a city sewer to be fed to the treatment plant,
    provided the industrial waste is free from heavy metals, toxic chemicals and is not
    abnormally acidic or alkaline.
    In such circumstances, scheme proposals have to carefully examine the case of
    integrating or segregating industrial wastes for purposes of conveyance and treatment
    as also the possibilities for appointment of capital and operating costs between the
    city authorities and the industries concerned.” (Emphasis added)
  12. Appearing on behalf of the Department of Environment, Government of India, Shri B.
    Dutta the learned First Additional Solicitor General of India placed before us a memorandum
    explaining the existing situation at Jajmau area of Kanpur. It read thus:
    “Status regarding construction of treatment facilities for treatment of wastes from
    Tanneries in Jajmau area of Kanpur:
  13. About 70 small, medium and large tanneries are located in Jajmau area of
    Kanpur. On an average they generate 4.5 MLD of waste water.
    155
  14. Under the existing laws; tanneries like other industries are expected to
    provide treatment of their effluents to different standards depending on whether
    these are discharged into stream or land. It is the responsibility of the industry
    concerned to ensure that the quality of the waste water conforms to the standards
    laid down.
  15. From time to time, tanneries of Kanpur have represented that due to lack
    of physical facilities, technical knowhow and funds, it has not been possible to
    install adequate treatment facilities.
  16. Jajmau is an environmentally degraded area of Kanpur. The location of
    numerous tanneries in the area is a major cause of the degradation. Civic
    facilities for water supply, sanitation, solid waste removal etc. are also highly
    inadequate. Because the area abuts the Ganga river, its pollution affects the river
    quality as well. Accordingly, under the Ganga Action Plan an integrated
    sanitation project is being taken up for the Jajmau area. Some aspects of the Plan
    relate to tannery wastes as follows:
    (i) The medium and large units will have to up up pretreatment facilities
    to ensure that the standard of sewage discharged into the municipal sewer
    also conform to the standards laid down. Scientific institutions such as
    Central Leather Research Institute are looking into the possibilities of
    pretreatment including recovery of materials such as chromium. The setting
    up of pre-treatment facility in the respective units will be the responsibility of
    the individual units concerned. The Ganga Project Directorate as part of the
    Ganga Action Plan, will play a facilitative role to demonstrate application of
    modern technologies for cost effective pre-treatment which the small tanners
    can afford.
    (ii) Since the wastes will be ultimately discharged into the river, the
    waste will have to further conform to the standards laid down for discharge
    into the stream. For this purpose, it will be necessary to treat the waste
    further and as part of the Ganga Action Plan a treatment plant will be
    constructed for this purpose utilising some advanced processes. It is also
    proposed to combine the domestic waste with the industrial waste conveyed
    through the industrial sewer which will then be treated in a treatment plant.
    (iii) It is estimated that cost of this proposed sewage treatment facility
    which will treat the waste from the domestic sources and the pretreated
    wastes from tanneries will be about Rs.2.5 crores. It will have a capacity of
    25 MLD and the first demonstration module of about 5 MLD is expected to
    be installed in early 1988-89. Necessary work for designing of the plant has
    already been initiated and the infrastructure facilities such as availability of
    land, soil testing etc. have also been ensured. Tender specifications are being
    provided and it is expected that the tenders will be floated sometime in
    October 87. It is expected that in the combined treatment facility of 25
    MLD, about 20 MLD will be from the domestic sources and 5 MLD will be
    from the tanneries after pretreatment in the region.”
    156
  17. In the counter-affidavit filed on behalf of the Hindustan Chambers of Commerce, of
    which 43 respondents are members it is admitted that the tanneries discharge their trade
    effluents into the sewage nullah which leads to the municipal sewage plant before they are
    thrown into the river Ganga. It is not disputed by any of the respondents that the water in the
    river Ganga is being polluted grossly by the effluent discharged by the tanneries. We are
    informed that six of the tanneries have already set up the primary treatment plants for carrying
    out the pretreatment of the effluent before it is discharged into the municipal sewerage which
    ultimately leads to the river Ganga. About 14 of the tanneries are stated to be engaged in the
    construction of the primary treatment plants. It is pleaded on behalf of the rest of the
    Tanneries who are the members of the Hindustan Chambers of Commerce and three other
    tanneries represented by Shri Mukul Mudgal that if some time is given to them to establish
    the pre-treatment plants they would do so. It is, however, submitted by all of them that it
    would not be possible for them to have the secondary system for treating waste water as that
    would involve enormous expenditure which the tanneries themselves would not be able to
    meet. It is true that it may not be possible for the tanneries to establish immediately the
    secondary system plant in view of the large expenditure involved but having regard to the
    adverse effect the effluents are having on the river water, the tanneries at Jajmau, Kanpur
    should, at least set up of the primary treatment plants and that is the minimum which the
    tanneries should do in the circumstances of the case. In the counter-affidavit filed on behalf
    of the Hindustan Chamber of Commerce it is seen that the cost of pretreatment plant for ‘A’
    class tannery is Rs. 3,68,000/-, the cost of the plant for a ‘B’ class tannery is Rs. 2,30,000/-
    and the cost of the plant for ‘C’ class tannery is Rs. 50,000/-. This cost does not appear to be
    excessive. The financial capacity of the tanneries should be considered as irrelevant while
    requiring them to establish primary treatment plants. Just like an industry which cannot pay
    minimum wages to its workers cannot be allowed to exist a tannery which cannot set up a
    primary treatment plant cannot be permitted to continue to be in existence for the adverse
    effect on the public at large which is likely to ensue by the discharging of the trade effluents
    from the tannery to the river Ganga would be immense and it will outweigh any
    inconvenience that may be caused to the management and the labour employed by it on
    account of its closure. Moreover, the tanneries involved in these cases are not taken by
    surprise. For several years they are being asked to take necessary steps to prevent the flow of
    untreated waste water from their factories into the river. Some of them have already complied
    with the demand. It should be remembered that the effluent discharged from a tannery is ten
    times noxious when compared with the domestic sewage water which flows into the river
    from any urban area on its banks. We feel that the tanneries at Jajmau, Kanpur cannot be
    allowed to continue to carry on the industrial activity unless they take steps to establish
    primary treatment plants. In cases of this nature this Court act affecting or likely to affect the
    public is being committed and the statutory authorities who are charged with the duty to
    prevent it are not taking adequate steps to rectify the grievance. For every breach of a right
    there should be a remedy. It is unfortunate that a number of tanneries at Jajmau even though
    they are aware of these proceedings have not cared even to enter appearance in this Court to
    express their willingness to take appropriate steps to establish the pretreatment plants. So far
    as they are concerned an order directing them to stop working their tanneries should be
    passed. Those tanneries who have already put up the primary treatment plants may continue to
    157
    carry on production in their factories subject to the condition that they should continue to keep
    the primary treatment plants established by them in sound working order.
  18. Shri S.K. Dholakia, learned counsel for the other tanneries who are members of the
    Hindustan Chambers of Commerce and the other tanneries who have entered appearance
    through Shri Mukul Mudgal submits that they will establish primary treatment plants within
    six months and he further submits that in the event of their not completing the construction of
    the primary treatment plants as approved by the State Board (respondent 8) and bringing them
    into operation within the period of six months the said tanneries will stop carrying on their
    business. We record the statement made by the learned counsel and grant them time till 31-3-
    1988 to set up the primary treatment plants. If any of these tanneries does not set up a
    primary treatment plant within 31.3.1988 it is directed to stop its business with effect from
    1.4.1988.
  19. We issue a direction to the Central Government, the Uttar Pradesh Board, established
    under the provisions of the Water (Prevention and Control of Pollution) Act, 1974 and the
    District Magistrate, Kanpur to enforce our order faithfully. Copies of this order shall be sent
    to them for information.
  20. The case is adjourned to 27th October, 1987 to consider the case against the municipal
    bodies in the State of Uttar Pradesh having jurisdiction over the areas through which the river
    Ganga is passing.
