Credit Interpretation Request
Off-site reclaimed water
Credit Interpretation Request Number
WAT4-C-RC1-0266
Ruling
2011-04-28
"The use of reticulated off-site reclaimed water is an acceptable way to reduce potable water consumption within the Green Star SA rating system. Although off-site harvesting and recycling systems are not specific attributes of the building seeking Green Star SA certification (as would be the case of an on-site water harvesting and recycling system), the fact that the building has chosen to incorporate the necessary infrastructure to connect their building services to the off-site service is, in this scenario, viewed as a building attribute.
The following additional documentation requirements apply where reticulated off-site reclaimed water is used:
For Green Star SA Design ratings;
• Evidence that the reclaimed water system is operational at the time of practical completion of the building.
• Confirmation from the off-site non-potable water supply vendor that the required supply is available to the project.
For Green Star SA As Built ratings;
• Evidence that the reclaimed water system is operational at the time of practical completion of the building.
• An extract from the contract between the off-site non-potable water supply vendor and the building owner must be provided."
