Rainwater harvesting to be made mandatory in Bangalore

Rainwater Harvesting is now mandated to be compulsory in Bangalore. This is applicable to already constructed buildings not just new buildings. 

See https://www.thehindu.com/2009/07/24/stories/2009072453720400.htm 

Rainwater harvesting will be compulsory nine months after the legislation takes effect it seems.

Questions come to mind:

-- How seriously will this be implemented ?

-- A huge demand can be expected if this is indeed implemented. Where is the plan to meet that demand. Lots of trainings for masons and plumbers are needed

-- What is the role of the Water Portal in this situation ? How can we best respond ?

Questions, questions.
