Water, the elixir of life is the basic need for human survival. However, India is one of the most water-stressed countries in the world. While the country has a population of over 1.4 billion people which is just under 20% of the global population, it only has 4% of the world’s water resources. This means that the water per capita in India is less than in any other major country in the world.
The average water consumption in Indian households is about 135 liters per capita per day (lpcd). This varies by region, with urban households consuming more water than rural households. For example, the average water consumption in Delhi is 150 lpcd, while the average water consumption in rural Rajasthan is only 70 lpcd. This includes all the personal necessities like drinking water, brushing water, taking bath, usage in restrooms to common activities that involve water in the household routines like washing dishes, washing clothes, mopping the floors etc etc. The average Indian household uses about 20 liters of water to wash dishes and 40 liters of water to wash clothes which makes up for about 40% of the per capita consumption.
The water crisis in India is being caused by a number of factors; the prominent ones bring -
Population growth: The need for water is rising as India’s population keeps expanding. The nation’s already scarce water resources are under stress as a result of this.
