Panhandle Water
Planning Area
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

Population Growth
Panhandle Water
Planning Area
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
Planning Area
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

Municipal Demand Growth
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
Panhandle Water
Planning Area
Evaluations
� 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
Panhandle Water
Planning Area
Alternative Strategies
� Selected with entity input
� Evaluated using same
considerations for selected
strategies
� Included in 2016 Plan
