Per Capita Availability Of Water

The study “Reassessment of Water Availability in India using Space Inputs” has been carried out by CWC in 2019. The average annual water resources of the 20 basins of the country have been assessed as 1999.20 Billion Cubic Meters (BCM).

Per Capita Water Availability In India

  • The per capita water availability is estimated by dividing the annual average water availability by the population.
  • The average annual per capita water availability in the year 2011 has been assessed as 1545 cubic meters.
  • Further, based on the above study, the average annual per capita water availability may further reduce to 1486 cubic meters by 2021.
  • This is an average figure and will vary depending on the season and region. Water resource data is maintained basin-wise and not state-wise.

Water: A State Subject

  • Water being a State subject, steps for augmentation, conservation and efficient management of water resources are primarily undertaken by the respective State Governments.
  • In order to supplement the efforts of the State Governments, Central Government provides technical and financial assistance to them through various schemes and programmes.

  • Ministry of Housing & Urban Affairs has formulated guidelines for the States to adopt measures suitable to local conditions to promote recharge of groundwater.
  • The adequate focus has been given on the requirement of rainwater harvesting and water conservation measures in Unified Building Bye-Laws (UBBL) of Delhi, 2016, Model Building By­laws (MBBL), 2016 and Urban and Regional Development Plan Formulation and Implementation (URDPFI) Guidelines, 2014.
