Water conservation plans
• Saved 220,000 acre-feet
• 407,000 meters
• 130,000 leaks fixed
71.5 billion gallons
replaced or repaired
~5 percent of municipal use
annual reports for 2010
that’s a lot of leaks!

Water in the future…
• The cost of water will go up• Water conservation will become more important– Landscape watering– Water loss– Efficient fixtures
• Water reuse will increase• Other sources of water (desal) will become more
economically viable • Transfers from agriculture to municipal use
