TRANSCRIPT
Florida’s Water Resources
• About 54 inches of rain annually
• 7,700 lakes
• 50,000 miles of rivers and streams
• 700 springs (largest concentration in the world)
Water Consumption Consequences
Groundwater depletion: • Dries out wetlands • Lowers lake levels • Reduces spring flows • Increases occurrence of sinkholes• Impairs water quality from saltwater

• Reduced leaks• Precipitation rates
matched to plant water requirements
• Even distribution within zones
• Correct scheduling
Irrigation Goals
18
Reduce High-Volume Irrigation
• No more than 60% high-volume• Separate irrigation zones for turf and beds• NEVER put sprays and rotors on the same zone• Matched precipitation rates
19
• Correct design and installation• Pressure-regulation• Filtration needed with reuse• Bubbler number, placement
