What will it cost to get enough water?
Total capital costs : $30.98 billion
What will it cost if we do nothing?
• Businesses and workers: $9.1 billion in 2010, $98.4
billion in 2060
• Lost local and state taxes: $466 million in 2010, $5.4
billion in 2060
• About 85 percent of the state’s population will not
have enough water by 2060 in drought of record
Highlights of Region C Strategies
• Municipal Conservation and Reuse (over 1
million acre-feet per year by 2050)
• Connection of Existing Surface Water Supplies
• Toledo Bend Reservoir
• New Major Reservoirs
- Marvin Nichols
- Lake Fastrill
- Lower Bois d’Arc
- Ralph Hall
• Total Capital Cost of All Recommended
Water Management Strategies = $ 13.2 Billion
Highlights of Region H Strategies
 Conservation
 Transfer of Lake Livingston water via Luce
Bayou (up to 1.2 million acre-feet per year)
 Two new reservoirs:
- Allens Creek
- Little River (off-channel)
 Brazos River Authority system operations
 City of Houston wastewater reuse
Total Capital Cost of All Recommended Water
Management Strategies = $5.5 Billion
Highlights of Region K Strategies
• Lower Colorado-San Antonio Water System
(LCRA-SAWS) Water Project
• New water pipelines to Hays County
• Municipal and agricultural water conservation,
wastewater reuse, and desalination (up to 368
thousand acre-feet per year
Total Capital Cost of All Recommended Water
Management Strategies = $ 358.17 Million
Highlights of Region L Strategies
• Lower Colorado-San Antonio Water
System (LCRA-SAWS) Water Project
• Carrizo-Wilcox Aquifer strategies
• Edwards Aquifer strategies
• Conservation
• Total Capital Cost of All Recommended
