Dear community, We have pursued this credit with option 1 and have achieved 52.31% only with the use of high efficiency WC and urinals. Now, the reviewer has sent very weird comments for this credit stating that we have not demonstrated the non-potable water available for sewage conveyance. Well of course not because we do not plan to. There is rainwater collection in this project but only for irrigation purpose. And he does mention that we have provided documentation for WEc1 to confirm the availability of the quantity of the non-potable water claimed. This is true but we have demonstrated this quantity only to earn credit WEc1, nothing to do with WEc2. I am very tempted to think that the reviewer got confused between the credits and our intent in using rainwater but before I answer that, I would like to know if someone has encountered the same issue. With many thanks,

Hello, I have used the same strategy on projects and never been asked this question. Using treated water is one of the strategies not the only one to meet the requirements of this credit. Did you check the PI forms to see if there were any forms that indicated treated water? There has to be a reason for this confusion. Good luck and keep us posted. Devani
