2. Outdoor Water – Above Green

Landscaping

In accordance with DOD Memo “Water Use for Landscape Architecture on Department of Defense Installations/Sites”, potable water use is prohibited for irrigating new landscaping, other than for plant establishment.
For existing systems, if a building has a single water meter, reduce combined indoor and outdoor potable water use by at least 20% compared to building water use in 2007. Compare results to a baseline building, using the EPA WaterSense landscape water budget tool version 1.01 or later, or a Component approved tool.
Show preference for irrigation contractors who are certified through a WaterSense labeled program, or other industry-recognized credentialing programs.
Refer to UFC 3-201-02 for additional requirements.

Outdoor Water Metering

For existing irrigation system using potable water and serving more than 25,000 square feet of landscape, provide water meters/1/, when life-cycle cost-effective. Install advanced water meters to monitor outdoor potable water consumption, as required by DOD Utilities Meter Policy, 16 April 2013. \1\Meter configuration must comply with requirements of UFC 4-010-06.

For all other existing irrigation systems using potable water, meters are encouraged.
