  1990, 1992, 1997
• Early plans emphasized reservoirs

• 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

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

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 states 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

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 Cs 2060 Demand

• Under the existing plan, Region Cs 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

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

51
Why is it Important to Accurately Measure Water
Usage/Conservation Progress?

• TCEQ must consider before issuing permit for new
  water supply
• TWDB must consider before providing State funding
• Planners must consider whether savings can be
  relied upon for future water supply
• Suppliers must consider to assess value of
  investment in water efficiency strategies

52
Factors Affecting GPCD Calculation

• Water Usage Volume
• Population Related Usage
• Single Family Residential
• Multi-Family Residential
• Commercial Water Usage
• Institutional Water Usage
• Recreational/Public Water Usage
• Active Conservation Programs
• Water Use Accounting
• Regional Economic Condition
• Climate
• Availability of Water Supply
• Self-Supplied Users
• Water Pricing
• Amount of Reuse/Recycle

53
Factors Affecting GPCD Calculation

• Population
• Service Area Population
• Accuracy of Population Count
• Timeliness of Data
• Commuter Influx
• Growth vs. Mature Cities
• Regional Economic Condition

Current Issues Sourcing of Water from Oklahoma

• TRWD, City of Dallas, Upper Trinity RWD and NTMWD
  jointly pursuing deal to pump water from Oklahoma
• Water from Kiamichi River, Cache Creek and Beaver
  Creek basins
• 2001 Oklahoma moratorium on out-of-state sales
• TRWD challenged moratorium in federal court
• TRWD taking lead on negotiations with Oklahoma
• Aug. 2008 City of Irving signed agreement to
  purchase water from Hugo Lake in Oklahoma

64
Current Issues New Reservoirs

• Last major new reservoirs in area about 20 years
  ago
• Currently difficult to permit new reservoirs
• 4 major new reservoirs in Region C Plan
• Compare to 30 developed over last 50 years
• New reservoirs less than 20 of 2060 supply
• Sometimes least expensive and best option
• Special study commission formed to examine Region
  C and D supply issues

65
Current Drought Conditions
66
Public Involvement

• Attend public meetings, provide comments
• Participate in Summer 2010 public hearing(s) on
  Initially Prepared Plan, provide comments on
  draft plan
• Copies of IPP will be available in at least one
  major public library in each of the 16 Region C
  counties
• IPP also available on Region C website
• Meeting agendas and planning documents at
  www.regioncwater.org
• Sign up to receive the semi-annual Region C
  newsletter

67
Closing Thoughts

• Conservation is essential
• Reuse should be encouraged
• Additional new supplies are needed
• Environmental flow needs are an issue
• Interbasin transfers are essential

68
Closing Thoughts

• New reservoirs are also needed
• Current drought in Central Texas emphasizes
  importance of water supply, ample surplus
• Public is a vital part of water planning
• Now is the time for the public to take notice
