Metering
• 100% water metering – Metro San Diego
• Irrigation & buildings both metered
• Monthly reporting of data
• Data analysis
• Field checks
• Corrective action
• Metering is critical to measuring performance and
focusing resources on most important water
conservation opportunities!
Navy Region Southwest 4

Reducing Building Water Use

Using Data to Save Water
• Analyze data to detect
apparent anomalies,
trends, billing errors, etc.
• Follow up to see what is
causing anomalies
• Correct problems found
• Use data to ensure
problems resolved

with desert landscaping (top right) to
save 236 million gallons
• All Region bases implementing
xeriscaping – project at Naval Base
Ventura County shown at right
• Smart landscaping project at NAB
Coronado, bottom right
• NAS Lemoore using
recycled tires to replace
turf areas (bottom)
