  4. Background and History Texas Water Development Board and Planning

  5. The Big Picture – Texas Rainfall

  6. History – TWDB and Planning • In Texas, planning driven by drought • Texas Water Development Board (TWDB) founded in 1957 (1950-57 drought) • $200 million water development fund • Formal planning process • State plans from Austin in 1961, 1968, 1984, 1990, 1992, 1997 • Early plans emphasized reservoirs

  7. Regional Water Planning Process

  8. Regional Water Planning Process • Senate Bill 1 - Texas Legislature in 1997 • Spurred by 1996 drought • Population projected to double by 2060 • “Bottom up” water planning process • Texas Water Development Board • Adopted rules • Set out 16 regions • Named initial planning group members

  9. Regional Water Planning Areas

  10. Regional Water Planning Process • 50-year planning period • Project population and water demand • Existing supply • Evaluate need for additional water • Recommend strategies • Water right permitting and TWDB funding use plans

  11. 2007 State Water Plan

  12. Historical and Projected Population 50 45 40 35 30 Texas Population (Millions) 25 20 15 10 5 0 1900 1910 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 2020 2030 2040 2050 2060 Year Year Historical Projected

  13. Population Growth Rate

  14. Projected Demand

  15. Projected Demand

  16. Projected Supply

  17. Historical Groundwater Level Declines Water level decline in feet less than 50 or undetermined 50 to 100 100 to 200 200 to 300 300 to 400 400 to 500 500 to 800 greater than 800

  18. Needs • Texas does not have enough water today to meet future demand during times of drought

  19. Potential Shortages

  20. Strategies - Process • Regions identified 4,500 strategies • Evaluated strategies based on: • Water quantity and reliability • Financial costs • Impacts to environment and agriculture • Impacts to water quality • Other factors such as regulatory requirements, time required to implement, etc. • 9 million acre-feet per year in new supplies recommended

  21. New Supplies2007 State Water Plan – In Acre-Feet/Year

  22. Costs • Total capital costs: $30.7 billion

  23. Costs of Not Implementing Plan • 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

  24. Water Conservation • In 2007 State Water Plan • Municipal Conservation 600,000 ac-ft/yr • 47% Region C, 16% Region H • Irrigation Conservation 1,400,000 ac-ft/yr • 32% Region M, 24% Region O, 21% Region A, 10% Region K • Implementation continues

  25. Water Supply Issue: Reuse • Differing approaches to reuse • Direct: before return to stream – easy to permit • Indirect: returned to stream and rediverted – difficult to permit • Important part of future water supply • Should be encouraged

  26. Reuse in the 2006 Regional Plans • Projected for 1.66 million acre-feet/year by 2060 • Slight majority in Region C • Significant amounts in Regions D, H, K and L • Some reuse in 14 of 16 regions

  29. 2006 Region C Water Plan

  30. Water Supply for the Metroplex • Region C – 16-county area • Collin, Cooke, Dallas, Denton, Ellis, Fannin, Freestone, Grayson, Henderson (Trinity Basin portion only), Jack, Kaufman, Navarro, Parker, Rockwall, Tarrant and Wise • 1/4 of Texas’ population • 1/12 of Texas’ water use in 2000

  31. Region C - Geography

  32. Region C Water Supplies • 90% is surface water (vs. groundwater) • The primary rivers supplying water to the region – Trinity River, Red River, Sabine River and Sulphur River • 35 wholesale water providers and 351 water user groups (WWPs and WUGs) • 3 largest wholesale providers supply 75% (Dallas WU, Tarrant RWD, North Texas MWD) • ½ of the water used is returned to streams and lakes as treated effluent • Reuse could be a significant source of supply • A small but growing fraction is currently reclaimed and reused

  33. Region C – Currently Available Supplies and Projected Demands

  34. Region C – Water Supply Critical • Rapid population growth • Water supply critical to way of life, continued prosperity, protection of ecology and wildlife • Without additional water supply in Region C: • 2060 population reduced by over 1 million(7.7%) • 2060 employment reduced by nearly 700,000 jobs (17%) • 2060 annual regional income reduced by $58.8 billion (21%)

  35. Meeting Region C’s 2060 Demand • Under the existing plan, Region C’s 2060 sources of supply would be as follows: • 31% from currently available, connected supplies (surface and groundwater) • 26% from new water conservation and reuse • 23% from new connections to existing sources • 18% from development of new reservoirs • Additional supply from development of regional systems, system operation of reservoirs and use of groundwater

  36. Region C’s 2060 Supplies

  37. Meeting Region C’s Demand

  38. Largest Region C Suppliers –Dallas Water Utilities • Supplies many other communities • Current supply – Lakes Ray Roberts, Lewisville, Ray Hubbard and Tawakoni • Planned supplies: • Conservation • Reuse • Existing Lakes Fork, Palestine, Wright Patman • New Lake Fastrill

  39. Dallas’ Planned Supplies

  40. Largest Region C Suppliers –Tarrant Regional Water District • Supplies Fort Worth, Arlington, many others • Current supply – Lakes Bridgeport, Eagle Mountain, Cedar Creek, Richland-Chambers • Planned supplies: • Conservation • Reuse • Existing Toledo Bend Lake and Oklahoma supplies • New Marvin Nichols Reservoir

  41. TRWD’s Planned Supplies

  42. Largest Region C Suppliers –North Texas Municipal Water District • Supplies communities north and east of Dallas • Current supply – Lakes Lavon, Chapman, and Texoma, and reuse • Planned supplies: • Conservation • Additional reuse • Existing Toledo Bend, Texoma, Oklahoma water • New Marvin Nichols and Lower Bois d’Arc Reservoirs

  43. NTMWD’s Planned Supplies

  44. Development of 2011 Region C Water Plan Current Issues and Next Steps in the Planning Process

  45. Status of Planning Process • First Region C Water Plan: 2001 • Second Region C Water Plan: 2006 • Now working on 2011 Region C Water Plan • Special studies to examine emerging water supply issues • Water Conservation and Reuse Study • Toledo Bend Study (with Region I) • Direct and Indirect Reuse Study • Studies Pertaining to Localized Areas • Ellis, Johnson, southern Dallas, southern Tarrant • Parker & Wise Counties

  46. Planning Schedule • RCWPG public meetings • Sept. 28, 2009 • Nov. 9, 2009 • Jan. 2010 • Mar. 2010 • April 1, 2010: Initially Prepared Plan to TWDB • Summer 2010: Public hearings on IPP • Aug. 1, 2010: TWDB comments due • Oct. 1, 2010: final Region C Water Plan due • Dec. 31, 2010: TWDB Regional Plan review • Jan. 5, 2012: State Water Plan published

  47. Next Steps in Planning • Reviewing updated population, demand projections • Evaluating potentially feasible water management strategies • Examining current issues

  48. Current Issues in Planning • Implementing water conservation and reuse • Pursuing water from Oklahoma • Developing of selected new reservoirs • Drought response

  49. Current Issues –Implementing Water Conservation • North Texas often cited as “water hogs” • Comparisons difficult because no standard measure (GPCD not standardized) • Relatively high per capita municipal use • Low per capita overall use • Very little agricultural use • Low per capita industrial use

  50. GPCD Background • Gallons Per Capita Day (GPCD) • GPCD is a metric that has been used to track and compare water usage among cities in Texas • No Standard Methodology • Texas Commission on Environmental Quality (TCEQ) Method • Texas Water Development Board (TWDB) Method • Water Conservation Implementation Task Force (SB 1094) Method • Water Conservation Advisory Council (SB 3 & HB 4) Method
