Xeriscape Gardens
WAT-3-E-RET1-2048
Guidance
2017-10-04
Where a xeriscape garden (found under additional guidance p.g 214 of Retail TM) has been installed, provisions must be made to remove any 'above-ground terminal fittings' (e.g. sprinkler heads, drip circuits, etc.) irrigation system within twelve months and ensure that the landscape will not receive watering after that time.”
This does not have to include that the ‘underground piping and 'turf valves’ are to be removed, as the removal of extensive lengths of buried pipes and turf valves is disruptive to the landscaping, can incur moderate costs and goes against the concept of future-proofing and material efficiency.

Credit Interpretation Request
Off-site reclaimed water
Credit Interpretation Request Number
WAT3-C-RC1-0266
Ruling
2011-06-09
"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."
Technical Clarification
Non-permanent landscape
Technical Clarification Number
WAT3-T-RC1-0101
Guidance
2010-09-07
Non-permanent landscape, such as potted plants, planter boxes, or other non-insitu landscape features, either internally or externally located, which can be removed or relocated, are not considered part of the 'base building' and are therefore not within the scope of the Wat-3 credit. Irrigation demands for such non-permanent landscape are to be excluded from calculations to demonstrate compliance with the Credit Criteria.
Technical Clarification
Combined initiatives
Technical Clarification Number
WAT3-T-RC1-0102
Guidance
2010-09-07
It is an acceptable method to meet the Credit Criteria through a combination of some or all of the design initiatives noted in the Wat-3 Additional Guidance (i.e. xeriscape, water-efficient irrigation systems and non-potable water for landscape irrigation). If Project teams elect to meet the Credit Criteria using a combination of initiatives, the established reference case, the proposed savings of each inititative and the overall savings must be clearly communicated in the documentation.
Technical Clarification
Groundwater
Technical Clarification Number
WAT3-T-RC1-0088
Guidance
2010-07-06
Groundwater seeping into building basements may be included as non-potable water in calculations for this credit. However, project teams must submit calculations of the quantity of groundwater available for use, clearly demonstrating reasonable assurance that the quantity calculated will be available in future. These calculations must be submitted for approval via CIR prior to project submission.
