Water efficient landscaping: no potable water use or no irrigation

WEc1.2 | Possible 1 point


Eliminate the use of potable water, or other natural surface or subsurface water resources available on or near the project site, for landscape irrigation.


Option 1

Achieve WE Credit 1.1.and:
Use only captured rainwater, recycled wastewater, recycled greywater, or water treated and conveyed by a public agency specifically for non-potable uses for irrigation.


Install landscaping that does not require permanent irrigation systems. Temporary irrigation systems used for plant establishment are allowed only if removed within one year of installation.

For projects that are part of a master plan development

If landscape irrigation for the project is part of a master plan, enter aggregate data in the Submittal Template. Submit appropriate documentation supporting the design of the rainwater collection system, the landscape design, and the extent of the supplemental temporary irrigation system.
Landscaping in the larger context of the master plan provides abundant opportunity to implement solutions that require less water and for capturing rainwater or recycled water. Large developments may consider treating its buildings’ wastewater to standards for non-potable uses.
