Tamil Nadu has ordered a statewide rainwater harvesting (RWH) campaign to improve water conservation and groundwater recharge.
The campaign will revive existing RWH structures and create new facilities in houses, apartments, institutions, commercial buildings and industries.
Check dams and soak pits will be built near water-drawing points to improve groundwater recharge, while damaged systems will be repaired.
Tamil Nadu has introduced RWH as a State policy in 2002, making harvesting structures mandatory for buildings.
1,202 firkas (revenue subdivisions), groundwater levels were found to be comfortable in 476 firkas.
