Please rate this resource: 

The intent of this credit is to reduce potable water consumption for irrigation to minimize the demand on limited supplies and reduce water costs.

Requirements for Certification:

Reduce potable water consumption for irrigation by 50% over a theoretical baseline design for the specific region.

Successful Strategies:

  • Drought tolerant plants
  • Drip irrigation, moisture-sensing irrigation technologies
  • Recycled rainwater system
  • Municipally-provided non-potable water source use


Helpful Hints:

  1. Look to similar existing building types or typical practices used by developers implementing water intensive landscaping to establish a reasonable baseline.
  2. Campus applications may require revisions to campus standards to allow the native/adaptive plantings. Xeriscaping may not be applicable in all high-usage areas.
  3. Some native plants may not be appropriate for facilities where allergies or compromised immune systems are of primary concern.
  4. Non-potable water systems (untreated irrigation water) may be prone to problems with mineral deposits in irrigation piping and nozzles.
  5. Over 400 water recycling plants are currently built or under construction throughout California . Projects should check with the local city water department for municipally provided non-potable water.


Historical Data (updated June 2006):

  • 79% of all California LEED Certified projects achieved this credit for LEED v2.1.
