Highlightsof the 2007
Texas Water Plan
Population and water demand continues growing while existing
water supplies decrease.
![Page 4: Water for Texas U.S. Conference of Mayors Water Board Meeting West Palm Beach, Florida Nov. 19-20, 2008.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649ee65503460f94bf6b55/html5/thumbnails/4.jpg)
• Population in Texas is expected to more than double between the years 2000 and 2060, growing from about 21 million to 46 million.
• The demand for water in Texas is expected to increase by 27% from 17 million acre feet of water in 2000 to 21.6 million acre feet in 2060.
![Page 5: Water for Texas U.S. Conference of Mayors Water Board Meeting West Palm Beach, Florida Nov. 19-20, 2008.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649ee65503460f94bf6b55/html5/thumbnails/5.jpg)
• Existing water supplies and the amount of water that can be produced* are projected to decrease by 18% from 17.9 million acre feet in 2010 to 14.6 million acre feet in 2060**.
*With current permits, current contracts, and existing infrastructure
**This decrease is primarily due to the accumulation of sediments in reservoirs and the depletion of aquifers.

The Need
•Texas will need an additional 8.8 million acre feet of water by 2060.
![Page 7: Water for Texas U.S. Conference of Mayors Water Board Meeting West Palm Beach, Florida Nov. 19-20, 2008.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649ee65503460f94bf6b55/html5/thumbnails/7.jpg)
•The planning groups identified 4,500 water management strategies and projects to generate an additional 9.0 million acre feet a year of water supplies for Texas.
•The planning group estimates that the capital cost to design, construct, or implement the 4,500 water management strategies and projects would be approximately $30.7 billion.

If Texas Does Not Implement the
Water Plan:• Water shortages during drought
could cost businesses and workers in Texas $9.1 billion by 2010 and $98.4 billion by 2060.
• About 85% of the state’s population will not have enough water by 2060 in drought conditions.

• The Dallas/Fort Worth (DFW) Metroplex is currently the fourth largest metropolitan area in the United States. The population grows by a million people every seven years, faster than any other area in the United States.
![Page 12: Water for Texas U.S. Conference of Mayors Water Board Meeting West Palm Beach, Florida Nov. 19-20, 2008.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649ee65503460f94bf6b55/html5/thumbnails/12.jpg)
• The present population is 6.5 million and projected to be 13.1 million in 2060.
• The DFW Metroplex, with a total of 12 counties in Region C, will represent 27% of the state’s population by 2010.
![Page 13: Water for Texas U.S. Conference of Mayors Water Board Meeting West Palm Beach, Florida Nov. 19-20, 2008.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649ee65503460f94bf6b55/html5/thumbnails/13.jpg)
• Collin County is the fastest growing county over 500,000 in the U.S.
• McKinney has been the fastest growing city in the U.S. and continues to be one of the top 3 cities in growth to a current population of 125,000.

The Goal
• The City of McKinney and Texas AgriLife Research and Extension Urban Solutions Center in Dallas are partnering on a six-year plan to educate and bring research based innovations to McKinney residents. Our goal is to manage our resources efficiently.
![Page 16: Water for Texas U.S. Conference of Mayors Water Board Meeting West Palm Beach, Florida Nov. 19-20, 2008.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649ee65503460f94bf6b55/html5/thumbnails/16.jpg)
• Fifty percent of all the water used in the DFW Metroplex is used on landscape, ballfields, golf courses, etc.
• By introducing a new drought-tolerant grass in these areas, we could cut water consumption by 50%.
![Page 17: Water for Texas U.S. Conference of Mayors Water Board Meeting West Palm Beach, Florida Nov. 19-20, 2008.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649ee65503460f94bf6b55/html5/thumbnails/17.jpg)
• Currently, McKinney has test areas throughout the city, and once this pilot project is completed, this grass can be used throughout Region C and could eliminate the need for one reservoir.

City of McKinney Estimated Indoor and Outdoor Use in 2005
In 2005, McKinney’s estimated outdoor use was 4,017.46 MG (48.56% of total use). Cutting it in half would have saved
2,008.7 MG (6,160 acre-feet).
In 2005, NTMWD’s total estimated outdoor water use was 40,765 MG (42.08% of total use). Cutting it in half would have
saved 20,382 MG (62,573 acre-feet).
