 What is a Water body?

  • The census defines a water body as all natural or man-made units bounded on all sides with some or no masonry work used for storing water for
    • Irrigation or
    • Other purposes (example industrial, pisciculture, domestic/drinking, recreation, religious, groundwater recharge, etc).

  • Water being a State subject, steps are primarily undertaken by the respective State Governments.
  • In order to supplement their efforts, the Central Government provides technical and financial assistance through various schemes and programmes.
    • For example, Repair, Renovation and Restoration (RRR) of Water Bodies under Pradhan Mantri Krishi Sinchayee Yojana (PMKSY)- Har Khet Ko Pani (HKKP) scheme provides for the restoration of water bodies.
  • There is the need for taking necessary steps for keeping all the water bodies encroachment free, such as
    • Inclusion of water bodies in land records,
    • Making them integral part of town planning process,
    • Strict action for the encroachers, etc.
