TIRPUR CASE All ground water studies  indicated  that open wells and bore wells in and around Tirupur exhibit high levels of  TDS (3000 - 11,000 mg/L) and chloride (2000 -  5000 mg/L).  These values are much higher than the permissible limits.  The surface water studies indicated that the Noyyal river (the river passing through Tirupur) which receives the major share of effluents and the downstream reservoir (Orthapalayam)  have been affected by industrial pollutants to point of no returns

Around 60-70% of water consumed in chemical processing is used for washing operations.  The wash water is obviously less polluted  compared to water used for actual chemical treatment.  It is therefore suggested that the wash water may be separated from the processed water,  treated separately and can be conveniently recycled.  Even if part of the wash water is recycled it will significantly reduce fresh water consumption.
.  There are also differences of opinion regarding the technology to be used for effluent treatment.  Many are of the opinion that reverse osmosis, popularly known as RO, provides an opportunity for the recycling of effluent water.  No doubt this is correct; however,  the capital cost of the equipment,  maintenance and operation costs make the use of RO  too expensive.
It is suggested that if the technology of RO is to be used in a economical way then it should be used for the purification of wash water  instead of using it for the purification of mixed effluent  which is more complex in nature and highly contaminated.

In addition to the effluent treatment, which is considered as end of pipe treatment,  attempts should also be made to reduce the pollution load of the effluent.  This is achieved by adopting the beginning of the pipe approach, also known as  cleaner production technology.

There is also a third principle,  profitable environment management (PREMA)  for reduction of water consumption and environment protection.  This focuses on good house keeping.

While speaking at a meeting organized by the Federation of Indian Chamber of Commerce and Industries (FICCI) at New Delhi in March 2001,  the United Nations General Secretary Mr. Kofi Annan warned that it is extremely important for all the countries around the world to manage water, particularly drinking water, properly without which it might lead to serious war like situation among various countries.
These two statements indicate the seriousness of situation at the water front and  Water crisis ahead
LETTER WRITTEN  IN THE YEAR 2070 www  ww w  www w Wwwwww w  w  ww w wwwwwwww wwwwwww  w w w wwwww  ww w w w www wWwwwww w  w  ww w wwwwwwww wwwwwww w w ww  www  ww w  www wWwwwww w  w  ww w wwwwwwww wwwwwww  w w w wwwww  ww w w w www w Wwwwww w  w  ww w wwwwwwwwWwwwww w  w  ww w wwwwwwww wwwwwww  w w w wwwww  ww w w w www wWwwwww w  w  ww w wwwwwwww wwwwwww w w ww  www  ww w  www wWwwwww w  w  ww w wwwwwwww wwwwwww  w w w wwwww  ww w w w www w Wwwwww w  w  ww w wwwwwwww Article published in the magazine  "Crónicas de los Tiempos“, in April 2002.
  This is  the  year 2070 I have just turned 50, but I my appearance is of somebody of 85 . I suffer from serious kidney problems, because I do not drink enough water.   I'm afraid I do not have  much time left to live. I am one of the oldest people  in this society.
I remember when I was a child of 5.  There   were lots of trees in the parks, houses with beautiful gardens,  and I could enjoy having a shower for half an hour.   Everything was very different then.  Nowadays we use towels with mineral oil to clean our skin.
Before,  women had beautiful hair. Then, my father washed his car with  water coming out of a hosepipe.  Now,  my son does not believe that  water could be wasted that way.  Now, we have to shave our heads  to keep them clean without the use of water.
I remember there were  SAVE WATER warnings on outside posters, radio and TV, but nobody paid attention.  We thought that water  was to last forever. Now, all the rivers, lakes, dams and underground water beds are either dry or contaminated.
Industry came virtually to a standstill and unemployment  reached dramatic proportions.  Desalination plants are the main source of employment  and workers receive part of their salary in drinkable water.
Assaults at gun point on the streets for a jerrycan of water are very common.  Food is 80% synthetic.
Before, the recommended quantity of water to drink  for an adult was 8 glasses a day. Nowadays, I am only allowed half a glass. We now have to wear disposable clothing,  and this increases the amount of litter.  We are using now septic tanks,  because the sewerage system does not work for lack of water.
The outside appearance of the population is horrible: wrinkled, emaciated bodies, due to dehydration, full of sores caused by ultra violet radiation,  now stronger without the protective shield of the ozone layer. Skin cancer, gastrointestinal infections and of the urinary tracts  are the main causes of death.
Due to the excessive drying of the skin young people of 20 look like 40.  Water cannot be produced, oxygen is also degraded due to the lack of trees and vegetation, and the intellectual capacity of the new generations is severely impaired. Scientists investigate, but there's  no solution to the problem.
The morphology of spermatozoa in many men has changed. As a consequence, babies are born with deficiencies, mutations and physical deformities.
Government makes us pay for the air we breathe,  137 m3 per day per adult person. People who cannot pay are expelled from the "ventilated zones", with huge mechanical lungs driven by solar power.  The air is not of good quality, but at least people can breathe. The average life expectancy is 35 years.
In some countries, where there are still some green zones crossed by rivers, these are guarded by heavy armed soldiers.  Water became a very coveted treasure, more precious  than gold and diamonds.
Where I live, there are no trees, because it seldom rains.  When it happens to register some precipitation, it is of acid rain.  The seasons have been severely affected by the atomic tests and by contamination from the 20th century polluting industries. We were warned to look after the environment, but nobody cared.
When my son asks me to talk about my youth, I tell him about the green fields,  the beauty of the flowers, the rain, how pleasant was to swim and fish in the rivers and dams, to drink all the water we could, and how healthy people was.
Then, I feel a lump in my throat!  He asks: Daddy! Why there is no water?
I cannot help feeling guilty, because  I belong to the generation who contributed to the destruction of the environment or simply did not take into account all the warning signs.
Now our children  pay a very high price!
I sincerely believe that within a short time life on earth will not be possible,  as the destruction of nature reached now an irreversible stage.
How I would like to go back and make mankind understand…   ...that we still had time to save our Planet Earth.
This show was made by a most very talented person, named  A P J Abdul Kalam I thank you.

  • 26.   This is the year 2070 I have just turned 50, but I my appearance is of somebody of 85 . I suffer from serious kidney problems, because I do not drink enough water. I'm afraid I do not have much time left to live. I am one of the oldest people in this society.
  • 27. I remember when I was a child of 5. There were lots of trees in the parks, houses with beautiful gardens, and I could enjoy having a shower for half an hour.   Everything was very different then. Nowadays we use towels with mineral oil to clean our skin.
  • 28. Before, women had beautiful hair. Then, my father washed his car with water coming out of a hosepipe. Now, my son does not believe that water could be wasted that way. Now, we have to shave our heads to keep them clean without the use of water.
  • 29. I remember there were SAVE WATER warnings on outside posters, radio and TV, but nobody paid attention. We thought that water was to last forever. Now, all the rivers, lakes, dams and underground water beds are either dry or contaminated.

  • 33. The outside appearance of the population is horrible: wrinkled, emaciated bodies, due to dehydration, full of sores caused by ultra violet radiation, now stronger without the protective shield of the ozone layer.

  • 34. Due to the excessive drying of the skin young people of 20 look like 40. Water cannot be produced, oxygen is also degraded due to the lack of trees and vegetation, and the intellectual capacity of the new generations is severely impaired. Scientists investigate, but there's no solution to the problem.

  • 36. Government makes us pay for the air we breathe, 137 m3 per day per adult person. People who cannot pay are expelled from the "ventilated zones", with huge mechanical lungs driven by solar power. The air is not of good quality, but at least people can breathe. The average life expectancy is 35 years.
  • 37. In some countries, where there are still some green zones crossed by rivers, these are guarded by heavy armed soldiers. Water became a very coveted treasure, more precious than gold and diamonds.
  • 38. Where I live, there are no trees, because it seldom rains. When it happens to register some precipitation, it is of acid rain. The seasons have been severely affected by the atomic tests and by contamination from the 20th century polluting industries. We were warned to look after the environment, but nobody cared.
  • 39. When my son asks me to talk about my youth, I tell him about the green fields, the beauty of the flowers, the rain, how pleasant was to swim and fish in the rivers and dams, to drink all the water we could, and how healthy people was.
