Would be be tap water..India seems to have not learn't how to conserve drinkable water for it's people .

Fortunately as far as i am aware NSL is utilising recycled water..(convert (waste) into reusable material).
not sure of the exact process they use for it .

NSL is working through operational/plant changes to enable the routine production of the +63% iron product. The short-term operational changes include the blending of higher grade feed as/when supplied by Infinity with existing plant feed.

The plant changes will incorporate the addition of a thickening circuit to the process flow to assist with water recycling. These changes will not affect the delivery into the Infinity order.

With the large demands for water often required in mining processes.
The inclusion of wastewater or sewage treatment plants in mining is almost mandatory and in the very least shows an organisation's commitment to water conservation.
Capturing water and treating it to the standards required for its various uses and then storing that water means a mine can utilise recycled water thus continue production without delays in times of drought. .
