UNIT I:
WATER CONSERVATION PLAN
Introduction
In accordance with the guidelines of the Texas Water Development Board (TWDB) the
City of Castroville has adapted a Water Conservation Plan via Ordinance 98-002 and
98-003 (Attachment A). The City Council adopted this ordinance on July 14, 1998, and
the Plan was subsequently approved by the TCEQ.
Effective October 7, 2004, the Texas Commission on Environmental Quality (TCEQ)
adopted revised rules and regulations pertaining to Water Conservation and
Drought Contingency plans requiring inclusion of new elements not previously required
in such plans. The City of Castroville’s current Plan substantially complies with the
revised rules. However, the TCEQ has reviewed the plan and found that a minor update
is required. Therefore, this document shall be considered the amendment to the current
Water Conservation and Drought Contingency Plans.
In order to meet requirements of the TCEQ, the City is to adapt a water conservation
and drought contingency plans entitled “City of Castroville Water Management Plan” by
Ordinance 2013-006 (Attachment B). The ordinance the City Council adopts shall
authorize the City to implement, enforce, and administer the program outline in this
Water Conservation and Drought Contingency Plan.
Utility Profile
Population and Customer Data
The City’s Water Services Department manages a water distribution service area of 2.4
square miles and serves a population of over 2960 residents. The City provides drinking
water to its customers through a network of nearly 25 miles of transmission and
distribution mains that provide service to over 1254 water connections. The information
within the utility profile includes the City of Castroville Wells (PWS # 1630005), the
Airport Well (PWS # 1630033) and the Medina Valley Well (PWS # 1630036). See
Attachment C for the full Utility Profile.
The official U.S. Census population count for the city in 2010 was 2,680, an increase of
about 19% from the 1990 Census. Population projections for Castroville, described in
the South Central Texas Regional Water Planning Area’s 2011 Regional Water Plan and
in the City of Castroville’s Master Plan 2011, forecast the City’s population will reach
3,316 by 2020, and 3,636 by 2030. In comparison, the City’s water demand projection is
expected to increase to almost 743 ac-ft (0.663 MGD) by 2020 and 802 ac-ft (0.715
ORDINANCE 2013-006 CITY OF CASTROVILLE

Based onTWDB-TAC31-363.15 Page 2 of 30
MGD) by 2030. References to the South Central Texas Regional Water Planning Area’s
2011 Regional Water Plan are in Attachment D.
Water Use Data
Table 1 below summarizes key water use statistics for 2008 to 2011. Average per
person usage is given in gallons per capita per day (gpcd). Average peak daily water
demand is given in million gallons per day (MGD). The peak day to average day ratio is
based on the Texas Commission on Environmental Quality (TCEQ) maximum daily
demand (30 TAC §290.38. (41))
§290.38. (41) Maximum daily demand -- In the absence of verified historical
data or in cases where a public water system has imposed mandatory water use
restrictions within the past 36 months, maximum daily demand means 2.4 times
the average daily demand of the system.
The maximum daily demand for the City is 1.38 MGD, reached in 2011. During high
demand periods when large volumes of water are being pumped from the aquifer, the
production capacity of the wells is reduced due to declining water levels of the aquifer.
The City’s water production and pumping system capacity is currently 2.692 MGD and
2.736 MGD, respectively.

Water Production and Delivery System
The City utilizes ground water for its public water supply and has developed its own
water production facilities. The City has five wells which withdraw groundwater from the
Edwards Aquifer. The distribution system is divided into three separate water systems
that are completely isolated from one another shown in Attachment E.
For the City System, all three wells pump directly into the distribution system. The
ground storage tank, located on a hill, provides water storage to the City System. The
City System also contains a separate pressure plane, referred to as the River Bluff
Pressure Plane that is serviced by a pressure tank and small pump station. The pump
station pumps directly into the River Bluff Pressure plane.
The Airport System is served by only one well, referred to as the Airport Well. The
groundwater is pumped to a small ground storage tank. From the ground storage tank,
a pump station pumps water into the airport system and the pressure tank. Some water

Water Conservation Plan
Based onTWDB-TAC31-363.15 Page 3 of 30
from the airport well is used by a local farmer to grow crops. The water at the airport is
used for normal airport operations.
The Medina Valley System is served by Well #6. Groundwater is pumped into one
ground storage tank, and a pressure tank. The water that is pumped from the well is
used to supply residential and commercial properties.
Specific, Quantified 5 & 10-Year Targets
Water Loss Goals
Castroville is undertaking a comprehensive effort to reduce unaccounted for water, and
to improve the quality of data in water loss estimates. It is expected that water loss
percentages will fluctuate annually with weather and demand conditions, and that some
fluctuations will occur as a result of improved data collection. Castroville intends to
increase its water conservation, and reduce its percentage of lost water as follows:

Implementation Schedule
The way the city plans on obtaining these water loss goals are described below:
1. Reduce per capita consumption through education by presenting non-wasteful
uses of water and techniques that can be employed to conserve water.
Information will be distributed in the local newspapers and other media outlets
during high-use seasons to expand public awareness.
2. Once a year, the City will review consumption patterns and its income and
expense levels and evaluate whether or not the current water rates are effective
and appropriate. A progressive water rate structure may be considered by the
City and adjustments will be made as needed.
ORDINANCE 2013-006 CITY OF CASTROVILLE
WATER MANAGEMENT PLAN
Water Conservation Plan
Based onTWDB-TAC31-363.15 Page 4 of 30
3. The City will provide information regarding the water rate structure to each of its
customers once a year. City will also provide customers with historical water use
for the previous 12 months upon request.
4. A leak detection and repair program will be maintained as well as a meter testing
and repair/replacement program.
5. Replacement of water lines found to be leaking or in generally poor condition will
be completed to ensure minimal water loss.
6. Require wholesale customers to adopt and implement the City’s water
conservation plan. This will be done as part of any new customer contract or
renewal of an existing customer contract to purchase water from the City.
Tracking of Water Conservation Plan Effectiveness
The City will keep track of the Water Conservation Plan’s progress via the following four
processes.
1. In order to track the effectiveness of water conservation measures, and to
monitor the water distribution system efficiency, the City already employs a
master meter, and a universal metering system. The master meter measures
any water diverted from the source into the water distribution system. The
universal metering system measures water used by customers and by public
sites. These provide the data required to track annual water use, and evaluate
progress towards the City’s goals.
2. The City will collect information about its programs and the population to evaluate
the effectiveness of the program at least once every three years. For literature
documents, the number of such documents and topics covered will be recorded.
The number of news programs or advertisements will also be recorded and the
total population of the service area will be tracked.
3. Guidelines for meter selection based on customer usage, meter replacement
policies, and records on each meter in the system will be recorded and
maintained.
4. To control water theft, and water loss (both real and apparent), the City has
developed schedules for meter inspection and maintenance, and visual line
inspection. This schedule will be part of a continuous program of leak detection,
repair, and water loss accounting.
a. These will be done on a monthly basis:
i. Visual inspection of all distribution lines
ii. Inspection of all commercial meters to check accuracy
ORDINANCE 2013-006 CITY OF CASTROVILLE
WATER MANAGEMENT PLAN
Water Conservation Plan
Based onTWDB-TAC31-363.15 Page 5 of 30
b. A water audit to detect water theft and abandoned services
Continuing Public Education & Information
Through education and information dissemination, the City will continue to inform its
water customers of the benefits of water conservation. The City will accomplish this by
implementing the following steps:
1. The City will provide information to all new customers describing the water
conservation program upon application for service.
2. The City will have available for free distribution pamphlets and tips on water
saving fixtures for homes and businesses, use of water conserving landscaping,
recycling of water, and reuse of water.
3. On an annual basis the City will request that local newspapers publish water
conservation literature.
4. The City Administrator will report annually on the effectiveness of the City’s water
conservation measures and the per capita water usage. If the Water
Conservation Plan is not effective, the City Administrator will make
recommendations for modifying the plan to increase its effectiveness. The City
Administrator will send a copy of the annual report to the executive administrator
of the Texas Water Development Board.
Water Rate Structure
The City currently has adopted a cost-based rate structure which encourages customers
to reduce both peak and overall water usage. The water rates for the City are
documented in Ordinance No. 2012-15 below as Attachment F. This rate structure will
be reviewed on a regular basis to ensure that the rates adequately recover the cost of
service and meet the goals of this water conservation plan.
Edwards Aquifer Authority Best Management Practices
The Edwards Aquifer Authority (EAA) requires the implementation of Best Management
Practices (BMPs) for Groundwater Conservation. For a community the size served by
Castroville, the EAA requires the implementation of Muni 1-7 as outlined in the Municipal
Groundwater Conservation Plan Form produced by the EAA (See attached Attachment
G). The City intends to implement these BMPs by completing the following programs:
Muni-1: System Water Audit, Leak Detection and Repair
ORDINANCE 2013-006 CITY OF CASTROVILLE
WATER MANAGEMENT PLAN
Water Conservation Plan
Based onTWDB-TAC31-363.15 Page 6 of 30
1. The City will develop an annual pre-screening water audit program to determine
real and apparent water losses.
2. In the event that the City is unable to account for 85% of the system’s water use,
the City will have a leak detection and repair program implemented to reduce
water loss.
3. Upon completion of the leak detection program, the City will provide the EAA with
measures to prevent future water loss
Muni-2: Metering of All New Connections and Retrofit of Existing Connections
1. The City will develop a document that outlines how the City is to install meters on
new connections.
2. The City will produce a feasibility study showing the benefit of having
landscaping irrigation meters on industrial and commercial accounts and
determine the best approach to controlling irrigation usage.
3. The City will develop a program and schedule to test and replace meters within
the service area.
4. The City will develop a feasibility study to retrofit multi-family and industrial,
commercial, and institutional (ICI) accounts with turbo meters or similar
technology that accurately reads flows.
Muni-3: Water Waste Prohibition
1. The City will develop a policies and enforcement programs to prohibit water
waste from property, landscape watering commercial activities.
Muni-4: Conservation Pricing
1. The City will maintain and update the cost-based water rate structure to
encourage customers to reduce both peak and overall water usage.
2. The City will develop a seasonal or excess surcharge to reduce demand during
the summer months.
Muni-5: Public Information and School Education Programs
1. The City will continue and improve upon the water conservation education
program to all employees and the community that is being served.

To determine the unit cost for the 10% drought management scenario for Uvalde, the
following steps were completed. First, marginal costs for both the 5% and 10% scenarios were
calculated. For the 5% scenario, this is simply the total economic impact divided by 5% of the
total year 2010 demand (i.e., $3,375 / 304 acft = $11/acft). For the 10% scenario, a marginal
cost must first be calculated. This is calculated as the difference in total economic impact
between the 10% and 5% drought management scenarios, divided by 5% of the total year 2010
demand (i.e., ($20,263 - $3,375) / 304 acft = $56/acft). To calculate the unit cost for the 10%
drought management scenario, the marginal costs of the 5% and the 10% scenario are averaged
(i.e., ($11 + $56) / 2 = $33/acft).
4C.2.3 Yield from Drought Management Strategy
The yield associated with drought management is simply the year 2010 projected demand
ti
mes the appropriate percentage depending upon which scenario is used (5%, 10%, 15% or
20%). These values are summarized below in Table 4C.2-4.
4C.2.4 Drought Management Strategy Costs
For each selected WUG, risk factors for 5%, 10%, 15%, and 20% drought management
scenario reductions were calculated (Table 4C.2-5). For the 5% reduction scenario, the risk
factors ranged from 0.0005 for the City of Point Comfort, indicating there is very little risk of a
higher per capita use rate occurring than what occurred in the year 2000, to 0.1652 for the City of
Castroville, indicating a much greater risk of demand being greater than supply. For the 20%
scenario, the risk factors ranged from a low of 0.0136 for the City of Point Comfort to a high of
0.3113 for Atascosa Rural WSC. The risk factors associated with the commercial and
manufacturing uses in Kyle, New Braunfels, BMWD, and SAWA are 0.0713, 0.0170, 0.1730,
and 0.0820 respectively.
As described above, these risk factors were then used to determine an annual cost for a
planned supply less than demand for the year 2010 (Table 4C.2-6). For the 5% reduction
scenario, the annual cost ranged from $106 for the City of Point Comfort to a cost of almost $5.7
million for SAWS. For the 20% reduction scenario, the annual cost ranged from $4,979 for the

City of Point Comfort to a cost of almost $627.3 million for SAWS. The two most
important factors driving the annual cost are the risk factor and whether or not that WUG
supplies water for commercial and manufacturing purposes (at the 20% reduction level), as these
uses have high impact factors.
Finally, the annual cost data were used to calculate a unit cost so that comparisons could
be made with other potentially feasible water management strategies (Table 4C.2-7). For the 5%
scenario (supply equal to 95% of dry condition demand), the unit costs ranged from $9/acft/yr
for the City of Point Comfort to a high of $3,239/acft/yr for the City of Castroville. For the 20%
scenario (supply equal to 80% of dry condition demand), the unit costs ranged from $111 for the
City of Point Comfort to a high of $26,878 for BMWD. Again, the high unit costs for BMWD
are primarily due to the high risk factors (i.e., the year 2000 per capita was lower than in many
previous years) and the high economic impact factors associated with commercial and
manufacturing uses.
The SCTRWPG has found, and the San Antonio Water System (SAWS) has
demonstrated, that water user groups having sufficient flexibility to focus on discretionary
outdoor water use first and avoid water use reductions in the commercial and manufacturing use
sectors may find some degrees of drought management to be economically viable and cost-
competitive with other water management strategies. Recognizing that implementation of
appropriate water management strategies is a matter of local choice, the SCTRWPG
recommends due consideration of economically viable drought management as an interim
strategy to meet near-term needs through demand reduction until such time as economically
viable long-term water supplies can be developed. Hence, new demand reductions associated
with the 5 percent drought management scenario are shown as recommended at year 2010 for
each municipal water user group with projected needs for additional water supply at year 2010

.

In accordance with the SAWS 2009 Water Management Plan Update, 37,622 acft/yr is the drought management
supply (demand reduction) shown for SAWS in year 2010. This quantity is between the 15 and 20 percent drought
management scenarios presented in Table 4C.2-4.

Permit holders utilizing non-Aquifer alternative water in conjunction with Edwards Aquifer (Aquifer) water may be eligible
to reduce BMP requirements. Municipal permit holders may achieve smaller system status by replacing Aquifer usage with
usage of alternative water. This will be measured by the number of connections that are converted to alternative water
supplies. For example, a municipality with 12,000 connections is considered a large system and must meet large system GCP
requirements; if that municipality converts half of its connections to alternative water, it now has 6,000 Aquifer connections
and is considered a medium system.
If you have acquired a non-aquifer alternative water supply in addition to your Aquifer water, determine the number of
Aquifer connections that count toward BMPs by using the following formula: multiply the total number of all connections by
the ratio of the amount of water supplied from your Aquifer wells divided by the total amount of water used by the
municipality. The calculation will determine your number of Aquifer connections.
[Amount of Aquifer Use] ______ ÷ [Total Water Use] ______ x [Total Connections] ______ = ____________________
