4.2 PREDICTION OF IMPACTS ON WATER ENVIRONMENT
The proposed expansion project requires about 3700 cum/day of water. The total water
requirement after the expansion will be 3800 cum/day. This includes cooling water make
up for DRI, SMS, Rolling Mill, SEAF and in Power Plant Make-up water for Cooling,
make-up water for Boiler, DM Plant regeneration, service water and for domestic water.
The water requirement for the proposed expansion will be met from Chhuikansa Nallah /
Mahanadi River. The permission for withdrawal of water will be taken before operation of
the expansion project. There will not be any waste water generation from process and
cooling from the existing plant. The only waste water from the existing plant will be
sanitary waste water of 8 cum/day. The total effluent quantity expected from the proposed
expansion will be 383 cum/day and 391 cum/day inclusive of the existing plant. Closed
