Show answer
Answer: (D) Thermal power
Thermal power plants are the biggest consumers of water among all industries in India, accounting for about 88% of total industrial water use.
They require enormous quantities of water primarily for cooling purposes (cooling towers and condensers).
The other industries listed also use water but far less:
- Engineering uses about 5.05%
- Paper and Pulp about 2.26%
- Textiles about 2.07% of total industrial water use.
So thermal power is the clear answer.
Thermal power plants consume about 88% of India's total industrial water, primarily for cooling systems in power generation.
Water scarcity and thermal power expansion became major policy concerns around 2012-2013, making industrial water consumption patterns exam-relevant.
The question tests whether students know the difference between overall water usage sectors versus specifically industrial water consumption within manufacturing.

Thermal Power Plants: India's Largest Industrial Water Consumer
Thermal power plants consume 88% of India's total industrial water use
Water is primarily used for cooling in condensers and cooling towers
Coal-based thermal plants dominate India's electricity generation
Water scarcity poses major challenges to thermal power expansion
Why So Much Water?
Thermal power plants burn coal to create steam that drives turbines. After generating electricity, this steam must be condensed back to water using cooling systems. This cooling process requires enormous quantities of water — typically 3-5 liters per unit of electricity generated.

Industry | Share of Industrial Water Use | Primary Use |
|---|---|---|
Thermal Power | 88% | Cooling condensers and towers |
Engineering | 5.05% | Manufacturing processes |
Paper and Pulp | 2.26% | Pulp washing and processing |
Textiles | 2.07% | Dyeing and fabric processing |
India-Specific Context
Coal-based thermal power generates about 70% of India's electricity
Many thermal plants located in water-stressed regions like Rajasthan and Gujarat
NTPC (National Thermal Power Corporation) is India's largest thermal power generator
Government promoting supercritical technology to reduce water consumption per unit
Trap: Students often pick textiles thinking of water-intensive processes like dyeing, but thermal power dwarfs all other industries
Trap: Paper and pulp seems logical due to wood processing, but it's only 2.26% vs thermal power's 88%
Remember: The question asks for maximum consumer — thermal power is 17x larger than the next biggest industry
Industrial Water Use Pattern
Geography industries consumer of water
Industrial Water Consumption Patterns in India
Industry accounts for about 8-10% of India's total water consumption
Agriculture remains the largest water consumer at 80%+
Industrial water demand is growing rapidly with industrialization
Sectoral Water Distribution
While thermal power dominates industrial water use, India's overall water consumption is led by agriculture (irrigation), followed by domestic use, and then industry. However, industrial demand is growing fastest due to economic development.
Water-Intensive Industries Beyond Thermal Power
Industry | Water Use Characteristics | Key Challenges |
|---|---|---|
Steel | Cooling, washing, steam generation | Located near water sources like rivers |
Chemicals | Process water, cooling, cleaning | High pollution potential |
Sugar | Cane processing, steam generation | Seasonal water demand |
Cement | Dust suppression, cooling | Located in water-scarce regions |
Aluminum | Cooling, hydroelectric power | Energy and water intensive |
Geographic Distribution
Western states (Gujarat, Maharashtra) have high industrial water demand
River valleys preferred for water-intensive industries
Coastal areas increasingly use desalination for industrial needs
Zero Liquid Discharge policies being implemented in polluting industries
Don't confuse: Industrial water consumption within industry vs across all sectors — agriculture still dominates overall
UPSC pattern: Questions often test specific percentages and rankings within industrial water use
Water Resources Sectoral Demand
Geography
Sectoral Water Demand in India: Agriculture, Industry & Domestic
Agriculture: 80%+ of total water use, mainly for irrigation
Domestic: 10-12% for drinking, cooking, sanitation
Industrial: 8-10% but growing rapidly with development
India faces water stress with demand exceeding sustainable supply
