Background and History Texas Water Development Board and Planning

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

Regional Water Planning Areas

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

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

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 Supplies 2007 State Water Plan – In Acre-Feet/Year

Costs Total capital costs: $30.7 billion

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

Water Conservation In 2007 State Water Plan Implementation continues 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

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

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

Region C - Geography

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 – Currently Available Supplies and Projected Demands

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%)

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

Region C’s 2060 Supplies

Meeting Region C’s Demand

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

Dallas’ Planned Supplies

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

TRWD’s Planned Supplies

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

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

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

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

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

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

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

GPCD Background Gallons Per Capita Day (GPCD) No Standard Methodology 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

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

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

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

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

Current Drought Conditions

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

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

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
