Livestock Water Use
Although Livestock Water Use represents a small portion of Total Water
Use in the State, We are all very aware of how important the livestock
industry is to the State of Texas, it’s history and it’s future.
Livestock Water Use
TWDB Staff calculates annual Livestock water use for each County by gathering
Livestock population data from Texas Agriculture Statistics Service (TASS) and Applying
livestock water use coefficients.

Conservation & Planning Reporting Requirements
Required by TWDB or TCEQ for many utilities:
• Water conservation plans  Utility Profile
• Annual reports
• Water loss surveys
• 5-year implementation reports
• Drought contingency plans
• Water Use Survey
Purpose:
• Water conservation is a critical element to meeting the State's
long-term water needs
• For water utilities and their customers, conservation programs
are often more economical because they can postpone or
eliminate the need for new infrastructure

Water Conservation Plans
Water Conservation Plan (WCP), 31 TAC Chapter 363,
Subchapter A, Rule 363.15
The purpose of a WCP is to establish specific and quantified 5and 10-year goals for water use. The WCP should establish a
schedule for achieving those targets and goals, establish a
method of tracking progress, and establish a water rate
structure which is cost-based and which does not encourage
the excessive use of water.
Utility Profile ~ is part of WCP
• Evaluates water and wastewater systems
• Identifies customer use characteristics, water conservation
opportunities, and potential targets and goals.
• Assists with water conservation plan development and
ensures that important information and data is considered
when preparing the water conservation plan and its target and
goals.
Information includes:
• population served
• number of connections
• water supply system data
• history of water use
• waste water system data
Water Conservation Plans
Applicable to Entities With
•TWDB loans greater than $500,000
•Surface water right through TCEQ
•3,300 or more connections
Components
WCP should contain long-term elements such as ongoing education activities,
metering, water accounting and estimated water savings from water reuse and
recycling activities, leak detection and repair and other conservation activities.

Annual Reports
Water Conservation Annual Report (AR), 31 TAC Chapter 363,
Subchapter A, Rule 363.15(g)
An Annual Report is required from each entity that submits a
WCP. The Annual Report shall report annual progress in
implementing each of the minimum requirements in the WCP.
As the report form is completed an entity should review their
WCP to see if they are making progress towards meeting stated
goals.
*5year –Implementation Reports prepared for the TCEQ providing the
required information may be submitted to the TWDB to fulfill this reporting
requirement.
Annual Reports
Applicable to Entities with
• TWDB loans greater than $500,000
• 3,300 or more connections
• Surface water right through TCEQ
* Anyone with a requirement to have a Water Conservation Plan
Components
The Annual Report collects utility data on:
 Targets and Goals
 GPCD
Water Savings
 Water Loss
 Educational Programs
 Rebate & Retrofit Programs
 Rate Structures
 Metering & Meter Repairs

5 - year Implementation Report
TCEQ 5-year Implementation Report, 30 TAC Chapter 288,
Subchapter B
A water conservation plan is required from each entity with a
non-irrigation surface water right greater than 1,000 ac-ft/yr
or an irrigation surface water right greater than 10,000 acft/yr through TCEQ.
The 5-year Implementation Report shall summarize the annual
progress in implementing the 5-year goals in the WCP.
Submit to TCEQ by May 1, 2014, and every five years thereafter.
Water Loss Survey
Water Loss Survey, 31 TAC Chapter 358, Subchapter B, Rule
358.6
The purpose of a Water Loss Survey is to help conserve the
state’s water resources by reducing water loss occurring in the
systems of drinking water utilities. A Water Loss Survey is
required by all retail water utilities.
Water Loss Survey
• The TWDB Water Audit Worksheet is a "top down" audit and is
referred to as a "desktop" exercise using existing estimations
and records.
• Data is used in TWDB loan applications and in regional water
planning studies.
• Assists the utility to improve their delivery system and to reduce
revenue losses.
• Due to TWDB by March 31, 2011, and every five years
thereafter.
Drought Contingency Plans
Drought Contingency Plan (DCP), 30 TAC Chapter 288, Subchapter B
All wholesale public water suppliers, retail public water suppliers serving 3,300
or more connections, and irrigation districts must submit a DCP. Retail public
water suppliers serving less than 3,300 connections must prepare and adopt a
DCP and make the plan available upon request.
Often times the DCP is a component of the Water Conservation Plan.
• Submit DCP to TCEQ by May 1, 2014, and every five years thereafter.
• Provide a copy of DCP to Regional Planning Group.
Drought Contingency Plans
The Drought Contingency (Emergency Demand Management)
Plan is a strategy or combination of strategies for responding
to temporary and potentially recurring water supply shortages
and other supply emergencies.
• contains “triggers” to implement levels in required
reductions in use of water
• may include activities that are considered normal
water conservation practices
Municipal Water Use Data: Annual
Water Uses Survey
• Distributed annually to over 4000 public water systems
and municipal-type systems

Water Use Survey
Water Use Survey, Texas Water Code §16.012 (m)
The purpose of the Survey is to gather data to be used for long-term water
supply planning.
The new online survey can be accessed here:
http://www.twdb.state.tx.us/wrpi/wus/online.asp
Submit a Water Use Survey to TWDB annually.
Entities Surveyed
• Municipal entities that use
ground and surface water
– City owned systems (1,000)
– Water districts (700)
– Water supply corporations
(750)
– Private utilities supplying
residential, commercial, and
institutional water (1,500)
• Mandatory
response required
by the Texas
Water Code
Water Uses Survey:
What Information is Collected
• Water source information:
– Groundwater
– Surface water
– Reuse
• Purchased water
• Volume of intake
Water Uses Survey:
What Information is Collected
• Sales
– Wholesale water sales to other systems
– Sales to large industrial firms
• System information
– PWS ID
– Population served
– Connections by category
– Categorized sales volumes: SF, MF, C/I
Water Uses Survey:
How the Data is Used
• Groundwater pumping volumes used by
groundwater conservation districts
• Data is used in the regional water planning
process
• Water demand for municipal and industrial
needs are projected out 50 years at the county
level
Regional Water Planning Process
Per-Person Water Use in Planning
• Reported annually for cities (>500 population)
• Net Water Use
– Includes water use of residential, commercial, and
institutional users
– Includes self-supplied water users inside city
– No water sales to large industrial users
– No retail water sales to customers outside of city limits
• Population
– Texas State Data Center July estimates
Residential GPCD
HDR Service Area Boundaries Project
Accessing WUS Data
• Water Uses Survey data is available here:
http://www.twdb.state.tx.us/wrpi/wus/2008est/2008wus.asp
4)
Residential GPCD is the estimated water use for single family and multi-family residences, expressed on a per capita (population) basis. These
estimates, based on responses to questions recently added to the annual water use survey, are being published for the first time. The pilot display of this
data should be viewed in the context that, since the reporting of such data had not been historically required, different systems may categorize and report
residential water use differently. A dash ( - ) indicates that the primary utility for the city did not report realistic residential volumes in the 2008 survey.
No Return - The primary water utility for this city failed to return a 2008 water use survey.

Conservation & Planning Reporting Requirements
Required by TWDB or TCEQ:
• Water conservation plans
• Annual reports
• 5-year implementation reports
• Drought contingency plans
• Water Use Survey
Purpose:
• Water conservation is a very critical element to meeting the
State's long-term water needs
• For industries, conservation programs are often economical
because they can reduce operating and production costs, met
environmental needs, and play a role in positive marketing.
Industrial Water Data:

• Types of power plants in Texas
– Steam Turbines
– Gas Turbines
– Combined Cycle
– Nuclear
– Hydroelectric
– Alternative (wind/solar)
• Different types of plants have different water-use coefficients
• Water use in this sector is dominated by cooling process and
pollution control

How is it used?
Industrial water demand is projected out 50
years at the county level for
manufacturing, mining, and steam
