Assessing Rain Water Harvesting System - Advice, Consultant Required

Hello Experts, 

I am Shyma from Bangalore, Marathalli area. I need some suggestions regarding the validation of the Rain Water Harvesting System that has been installed in our apartment complex.

We require advice on the following parameters:

1. How to check if the system has been installed as per best standards or guidelines laid down for the same?

2. Is there a method to assess the efficiency of the installed system?

Do advice on the situation and do ask if further details are needed. 





1. Certification of Rain water harvesting system

Dear Shyma,

You can approach the Bangalore Water Supply & Sewerage Board (BWSSB) to come and inspect and certify that it has been done correctly.They will tell you if it has been done correctly,and, if not, what changes are needed.

If you can not get all this done, you can contact me for help.





2. We can help you with RWH

We are service providers for rainwater harvesting, dealing in filters and undertaking RWH on turnkey basis. We also do third party inspection of systems already installed and suggest corrections if needed.

BWSSB stipulates about 70% of the roof area to be harnessed to qualify for their RWH norms. Further, if you are tapping additional catchment area like paved open space, it will also count. We will be happy to be of assistance at reasonable charges.
