The Big Picture – Texas Rainfall
5
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
6
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



8
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
18
Potential Shortages
19
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

Costs
Total capital costs: $30.7 billion
22
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
23
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
24
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
25
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
29
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
30
Region C - Geography
31
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


32
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:



34
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%)
Meeting Region C’s 2060 Demand
 Under the existing plan, Region C’s 2060
sources of supply would be as follows:





35
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
Current Issues in Planning
 Implementing water conservation and reuse
 Pursuing water from Oklahoma
 Developing of selected new reservoirs
 Drought response
48
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


49
Very little agricultural use
Low per capita industrial use
GPCD Background

Gallons Per Capita Day (GPCD)


No Standard Methodology




50
GPCD is a metric that has been used to
track and compare water usage among cities
in Texas
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
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

IQ Program

59
DWU: 12 billion gallons saved in 2006
TRWD: 10 billion gallons saved in 2006
NTMWD: 10 billion gallons saved in 2006

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
63
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
64
Current Drought Conditions
65
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
66
www.regioncwater.org
 Sign up to receive the semi-annual Region C
newsletter
Closing Thoughts
 Conservation is essential
 Reuse should be encouraged
 Additional new supplies are needed
 Environmental flow needs are an issue
 Interbasin transfers are essential
67
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
