REIA Report for the Proposed Mini Integrated Steel Plant
Chapter – 4
circuit cooling system will be implemented and this will result in lower water consumption
and there will not be any effluent generation from the process & cooling in the steel plant.
The details of total water consumption, it's breakup and total waste water generation and
it's breakup are show in Table 4.2.1. & 4.2.2. Characteristics of waste are shown in Tables
4.2.3 to 4.2.6. The sanitary waste water will be treated in septic tank followed by soak pit.
Rain water Harvesting structures have been constructed in the existing plant and similarly it
will be continued with the help of Central Ground Water Board.. The depth of ground
water table will certainly increase. Hence there will not be any adverse impact on water
environment due to the proposed expansion.
