Industrial Water Consumption Assessment

Select Industrial Hub Tiruppur (Tamil Nadu) Panipat (Haryana) Other

Production Volume (P) [kg of fabric/year]

Water Intensity (I) [liters/kg] Low (80 L/kg) Medium (115 L/kg) High (150 L/kg)

Total Annual Water Demand (W_total)

0

Methodology

Total Annual Demand (W_total) = Production Volume (P) × Water Intensity (I)

Cotton textile processing typically consumes 80–150 liters of water per kg of fabric.

Interpretation & Conclusion

Resource Stress Classification

Based on Central Ground Water Board (CGWB) norms:

• Safe: Water level decline < 4m
• Semi-Critical: Water level decline 4-7m
• Critical: Water level decline 7-10m
• Over-exploited: Water level decline > 10m

Sustainability Gap Analysis The textile industry in this region shows significant water stress with groundwater depletion exceeding 10 meters. The rapid increase in industrial units has led to substantial water quality deterioration, with BOD and TDS levels increasing by over 600%. Implementation of Zero Liquid Discharge (ZLD) systems is critical. For example, Tiruppur has successfully implemented ZLD and now recycles nearly 90% of its water, which could serve as a model for sustainable water management in textile clusters.

Recommendations 1. Mandate Zero Liquid Discharge (ZLD) for all textile units 2. Implement water recycling and reuse systems 3. Conduct regular monitoring of groundwater levels 4. Enforce strict effluent treatment standards 5. Promote water-efficient technologies in textile processing 6. Develop rainwater harvesting systems in industrial areas 7. Create a water footprint accounting system for industries
