  • 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! Navy Region Southwest 4
  • 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 Navy Region Southwest 5
  • 6. Reducing Building Water Use Navy Region Southwest 6
  • 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 Navy Region Southwest 7
  • 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 Navy Region Southwest 8
