Dear all :- 

 we are working in a project with 100% non potable water (On site recycling water 0 using for both Flushing fixture and Irrigation)

As per LEED BD + C reference guide  we have come to know we may save claim that 50% claim by using recycle water / Efficient irrigation system in our case we have huge amount of recycle water so is it correct way to claim the saving via option 1 50% saving via recycle water 

Our doubts are 

1.is it enough if we use recycling water for 50% of total irrigation water consumption 

2.is it mandatory to show the irrigation saving via effective plants and irrigation for option 01 (in ref guide we may claim the saving via recycle water )
