I would like to know if there is any special validation to my situation:
We used to have irrigation from the faucets, what means an irrigation with potable water, but we are attempting to get the 100% reduction of potable water irrigation. That's why we placed a policy that forbids the irrigation with potable water; and we are implementing water storage tanks to harvest rain water and replace our irrigation source.
My question is if there's any way to certify this technique without having to fill the 3 possible options. Because we don't have an historical data to achieve option one. And considering a 100% reduction, I would think it will be obvious that the scope is being done.
