Total Water Consumption per Capita per Day in Indian cities

Definition:
The total water consumption per capita per day refers to the amount of water used by an individual on an average per day in a city.

IS Code:
As per the Indian Standard Code of Practice, the total water consumption per capita per day, including domestic, commercial, and industrial demands, for an average Indian city, may be taken as 270 liters per capita per day (l/c/d).

Explanation:
The total water consumption per capita per day in Indian cities is determined by several factors such as population density, climatic conditions, availability of water resources, and socio-economic conditions. The IS code has set a standard value of 270 l/c/d based on these factors.

The breakdown of the total water consumption per capita per day can be as follows:
- Domestic demand: This includes the water used for drinking, cooking, washing, bathing, and sanitation purposes. The domestic demand for water in Indian cities is estimated to be around 135 l/c/d.
- Commercial demand: This includes the water used by commercial establishments such as hotels, restaurants, and offices. The commercial demand for water in Indian cities is estimated to be around 20 l/c/d.
- Industrial demand: This includes the water used by industries for manufacturing processes, cooling, and other purposes. The industrial demand for water in Indian cities is estimated to be around 115 l/c/d.

Conclusion:
The total water consumption per capita per day in Indian cities is a critical factor in ensuring the sustainable use of water resources. The standard value of 270 l/c/d set by the IS code provides a benchmark for planning and designing water supply systems in urban areas. However, it is essential to adopt water conservation measures and promote awareness among the public to reduce water wastage and ensure the long-term availability of water resources.
