Background/ Project Rationale:

  • Kempegowda International Airport, Bengaluru under the management of BIAL is located in Devanahalli area which is 25 KM away from the city. The area is hydro geologically considered as over exploited area and the annual rainfall also substantially less than the rain fall of Bengaluru. KIAB’s current water requirement is around 3 MLD which will increase along with the proposed development of airport and its commercial area development. Currently BIAL getting its water requirement from BWSSB as well as treating the entire sewerage water for its landscape use. BIAL also has multiple rain water harvesting structures including dug wells within its operational area.
