2 ITC s Sustainability Report Water Management Approach Establish Overall Water Balance Reduce at source Reuse in other beneficial applications after treatment (land scaping, toilet flushing, cooling tower applications and civil constructions etc.,) Recycle back to process applications after appropriate treatment 2

3 Water Consumption Trend Water Consumption KLD Ser ies Year Please Note: Please Note: Water consumption increased by 8.7 % as production increased by 15.0 % compared to last year however the specific water consumption is reduced by 6 %. Specific Consumption Specific Water Consumption Index kl/mnc Please Note: Specific Water Consumption has reduced by 6 % 3

4 Specific Waste Water Discharge Qty generated (m 3 /day) Qty recycled (m 3 /day) Qty discharged Volumes Specific water Year (m 3 /day) (MNC) discharge (kl / mnc) Specific Waste Water Discharge '04 - '05 '05 - '06 '06 - '07 '07 - '08 Specific Water discharge. 4

Yearly Annual Water & EHS Report Director s Report Unit Achievement Report Beyond Equipment Performance. Performance appraisal of M anagers Water Conservation Projects CII Water Audit carried out in The following savi ngs potentials were identifi ed: Effluent discharge ( ) Reduction through recycle of MGF/IRF b/w water Reduction in domestic water consumption RO product for CT make-up RO reject for gardening & Toilet flashings Total 160 m 3 /day 30 m 3 /day 15 m 3 /day 50 m 3 /day 65 m 3 /day 160 m 3 /day Earlier Treated Discharge Water is being used by Local farmers for irrigation Small scale gardening inside factory 7
