This document discusses Navy Region Southwest's water conservation efforts across its major installations in southern California. It outlines that the region consumes approximately 4.6 billion gallons of water annually, with the largest users being NAWS China Lake and NAS Lemoore. The region has implemented extensive metering of buildings and irrigation systems to monitor usage. It has also reduced building water usage through installing low-flow fixtures and enforcing conservation practices. For irrigation, the region is upgrading systems with new controls and technology while replacing turf with desert landscaping. These efforts have led to an estimated annual reduction of 220 million gallons in water usage for the San Diego area installations.

4. 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!

5. Reducing Building Water Use
• Improving fixtures and equipment
– Installed 225 waterless urinals
– Planning installation of 160 ultra-low flow urinals
– Installed 6,000 1.5 gpm showerheads
– Installed 5,500 faucet aerators
• Enforcing best water management practices
• Training Building Monitors
• Monitoring buildings’ water performance

7. 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

8. Irrigation
• Installed irrigation in Metro San Diego is metered
• Focus on reduction during last several years
• Best opportunity for conservation
– Technology improvements
– Coordination with landscape contractors

9. Irrigation
• Actions
– Irrigation Manager position
– Improving irrigation infrastructure and controls past two
years at Metro San Diego installations (~$2.5M)
– Scientifically managing irrigation
• Refine irrigation schedules
• Match to plant types; appropriate fertilizing
– Replacing turf with smart landscaping, desert
landscaping, artificial turf, etc.
– Using “stakeholder” teams to improve irrigation practices
– Closely monitoring irrigation water use
– Winter shut-down of systems

10. Reducing Irrigation Water Use
Smart & Desert Landscaping:
• NAS Fallon replaced 95% of turf
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)
