Answer:

Saving our Water Resources

Dams

Dams are simply hydraulic structures that act as a barrier between the source and destination of flowing water. Earlier, these dams were small and hand-made. In our modern society, engineering techniques and methods are used to construct most of these dams.

Rainwater Harvesting

You must have come across this term from multiple media sources. Rainwater harvesting is one of the most efficient and effective ways of conserving water. It is more like the recycling of natural water. In this, the rooftop rainwater harvesting is a common practice in states like Rajasthan, West Bengal, Meghalaya, and major parts of South India, where rainfall is usually heavy. People connect PVC pipes to a drain on their roof and the rainwater is collected below in large storage tanks.

Bamboo Drip Irrigation system

This is an indigenous method which has been in practice for about 200 years in the north-eastern states of India. While this practice helps conserve the region’s water resources, it also helps in irrigation of local farms and fields. People use bamboo pipes for tapping the waters of streams and springs. About 18020 liters of water flow through a network of pipes and end up as drips on the farmlands.

Some quick Facts and Figures :

  • The total volume of water on earth’s surface- 96.5%
  • The total volume of usable freshwater- 2.5%
  • The volume of freshwater in ice-sheets and glaciers- 70%
  • Stored groundwater- 30%
  • Precipitation (rainfall) in India- 4% of earth’s total
  • India’s rank in the world for water availability per person (per annum)- 133
