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

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

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

Connect Surface Water, 3,300,000

Reuse, 1,300,000

New Reservoirs, 1,100,000

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
