The Big Picture – Texas Rainfall

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

Regional Water Planning Process

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

Needs
Texas does not have enough water today to meet future demand during times of drought
19
Potential Shortages

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
Connect Surface Water, 3,300,000
Reuse, 1,300,000
New Reservoirs, 1,100,000
Groundwater, 800,000
Municipal Conservation,

Desalination, 300,000
Irrigation Conservation,

Conjunctive Use, 200,000
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

2006 Region C Water Plan

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

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

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
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 CalculationI. 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

Implementing Water Conservation –Major Projects Conservation awareness programs
Dallas Water Utilities and Tarrant Regional Water District: “Save Water, Nothing Can Replace It”
DWU: 12 billion gallons saved in 2006 TRWD: 10 billion gallons saved in 2006
North Texas Municipal Water District: Water IQ Program
NTMWD: 10 billion gallons saved in 2006
60
Major Reuse Projects
Reuse projects totaling more than 730,000 acre-feet/year developed or in-progress: NTMWD East Fork Raw Water Supply Project TRWD George Shannon Wetlands Upper Trinity Regional Water District reuse of
Lake Chapman water Garland/Forney reuse for power plant Grapevine/Dallas County Park Cities

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
