State Population Projections

� County projections – State Data

Center

� demographic trends

� 50% net migration rate (2000-2010),

� TWDB did not decline populations

� WUG level

� Cities > 500 people

� WSCs > 280 acre-feet/year

� Census Designated Places

� County-Other

Panhandle Water

Changes to County Populations

� Cannot increase regional

population

� Criteria for county population

changes:

� Census undercount

� Different net migration rate

� Different birth/survival rates

Panhandle Water

Review and Changes to WUGs

� Lefors and Skellytown are no longer

WUGs (pop <500)

� Addition of WUGs

� Criteria for WUG population

changes:

� Census undercount

� Growth rate > growth between 2000-2010

� Expansion of city / utility CCN boundary

� Growth limits (build out)

DRAFT MUNICIPAL DEMANDS

Panhandle Water

Planning Area

Draft Municipal Water Projections

� Methodology

� Water use (GPCD) x Projected population

� Year 2011 GPCD

� Include Plumbing Codes reductions

� GPCD

� Net municipal water use (less industrial and wholesale sales)

� Minimum – 60 GPCD

Panhandle Water

Planning Area

Changes to Municipal Demands

� Must use 2011 as base year

� Criteria for municipal demand

changes:

� Errors in 2011 water use reporting

� Evidence that 2011 had temporary constraints

� Evidence of changing demographics that warrants higher GPCD

� Evidence of different PC replacement schedule

Panhandle Water

Planning Area

Review and Changes to WUGs

� Most GPCDs for 2016 plan are

higher than 2011 plan

� 2011 Plan used average use, not dry year

� Some significant differences in

historical GPCD

� High GPCD (need review)

� 2011 – Highest water use for

most cities (60%)

Panhandle Water

Planning Area

Next Steps

� Survey to Municipal WUGs

� Solicit input by May 15

� Review water use reports –

select WUGs

� Coordinate with TWDB – errors,

data needs

� RWPG approval of requested

changes (July or early August)

� Submit changes to TWDB by

August 16

Methodology –Water Management Strategies

PWPG MeetingAugust 6, 2012

Panhandle Water

Planning Area

Feasible Strategies

From TAC 357.5

“Before a regional water planning

group begins the process of

identifying potentially feasible

water management strategies, it

shall document the process by

which it will list all possible water

management strategies and

identify the water management

strategies that are potentially

feasible for meeting a need in the

region.”

Panhandle Water

Planning Area

Identification Process

� Identify entities with needs

� Review recommended strategies

in 2011 plan

� Determine if new or changed

strategies are needed

� Contact entity for input

� Contact PWPG representative for county-wide WUGs

� Verify recommendations

Panhandle Water

Planning Area

Feasible Strategies

� Considerations

� A strategy must use proven

technology

� A strategy should be appropriate for

regional planning

� A strategy should have an

identifiable sponsor

� Must consider end use. Includes

water quality, economics,

geographic constraints, etc.

� Must meet existing regulations

Panhandle Water

Planning Area

Feasible Conservation Strategies

� Water conservation � Review for applicability and develop

appropriate strategies for all municipal

and irrigation WUGs

� Applicable municipal WUGs > 140 gpcd

� Identify appropriate conservation

strategies for other types of water use;

apply to WUGs with a need

� Drought management � Emergency measures

� Generally, not recommended for long-

term

Panhandle Water

Planning Area

Feasible Strategies

� Expanded use of existing

supplies or new supplies

� New groundwater wells

� Consider groundwater availability

� Conjunctive use of groundwater &

surface water

� New infrastructure

� Voluntary Transfer

� Contracts

� Sales, leases and options

Panhandle Water

Planning Area

Feasible Strategies

� Desalination of brackish water

� Wastewater reuse

� Identify generators of wastewater and potential recipients for reuse

� Identify opportunity for expansion

� Yield enhancement

� Brush management

� Precipitation enhancement

� Recharge enhancement

� Quantity, cost and reliability

� Environmental factors

� Impacts on water resources and

other WMS

� Impacts on agriculture/ rural

� Impacts on natural resources

� Impacts on key water quality

parameters

� Other relevant considerations
