water in car manufacture

Post by scratcher »

Hi, does anyone know much water is used in the manufacture of a car? This should include quantities used in the manufacture of components. I remember reading about it in the1970's and it was quite a high figure.

Do you want to include the water used to generate the electricity used to make the parts as well?

That may explain why the figures above are high.

Including that could really skew your answer, the plant I worked in used (and returned to the sea) 4 million gallons a minute as condensor cooling, as well as mains water for feed water, I can't remember figures for that however.

This website:

reports that Toyota use 1.97m3 of water per car, which is just under 2 tonnes or 1970 litres. I don't know if that includes part manufacturing or electricity production.

Hi, interesting figures, considering our 'masters' say that parts of the world are getting very short of water. I presume the water used in larger production does not take into consideration the quantity relieved in the night! It does show how much our consumer society uses in production processes compared with third world use. Thanks for the replies. Gerry

No, it doesn't, because producing one tonne of steel uses 8 tonnes of water.

It don`t "use" any water.Just the cost of transporting it and cleaning it up.

Same amount of water here on planet earth that ever there was. There is no shortage of water? Just too many people....... wanting it in places it shouldn`t be..............Las Vegas :lol:

Oops, I should probably have known that, but it is a long time since I studied steel production.
