How to implement rain water harvesting for your house

February 02, 2012

Rainwater harvesting is the accumulation and storage of the rainwater through a process for the reuse and conservation of water. Since 2009, BWSSB has made it compulsory for all upcoming apartments and commercial buildings to make provisions for rainwater harvesting.

The Karnataka State Government is also offering a rebate of 5%-10% will be provided on the basis of water bills submitted by those who have installed water harvesting in their building/area.

Process requirements:

  • 1. Rainwater harvesting can be implemented by any person who is building a house or who already has a house and has space to set up the system.
  • 2 It is mandatory for houses who own 2400sq ft. and above or who wish to build house on an area of 1200sq ft. and above to install rain water harvesters in their houses before  December 31, 2011
  • 3. You can take help from the plumbers who have been trained by the BWSSB in installing rain water harvesting systems.  
  • 4. After installing RWH system in your home or apartment complex, ask for a copy of the certificate from the trained plumber / contractor and attach the same with two photographs of RWH in your house. Attach the same with a letter and submit them to the nearest BWSSB office.
