WHEREAS, the City Council of the City of Lubbock, Texas finds and determines
that it is in the best interest of the health, safety, and welfare of the citizens of the City of
Lubbock to make the following amendments to Chapter 22 of the Code of Ordinances of
the City of Lubbock; NOW, THEREFORE,
BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF LUBBOCK:
SECTION 1. THAT Section 22.08.001(x) of the Code of Ordinances, City of
Lubbock, Texas, is hereby amended to read as follows:
Sec. 22.08.001 Introduction
(a) The city is located in Lubbock County in the Texas Panhandle and is the
eleventh largest city in the state and the largest city in West Texas. The city's population
was estimated by the city planning department to be 242,843 in 2014. According to the
Llano Estacado (Region 0) Regional Water Plan, the city's population is expected to
increase to almost 232,000 by 2025, while the city's planning department estimates the
most probable population to be almost 278,000 by 2025. The city is situated in a semi-
arid region that requires more water per capita for landscape irrigation than in many other
parts of the state. Evidence of landscape irrigation demand is apparent when comparing
the average winter water usage of 121 gallons per capita per day (gpcd) to the average
summer water usage of 192 gpcd. In response to this, recent city efforts on water
conservation have focused on techniques to reduce the amount of water used in landscape
irrigation.
SECTION 2. THAT Section 22.08.002 of the Code of Ordinances, City of
Lubbock, Texas, is hereby amended to mad as follows:
Sec. 22.08.002 System description
(a) The city water system currently utilizes three separate water supply sources.
During 2014, approximately 60% of the city's annual water usage will be supplied from
the Canadian River Municipal Water Authority (CRMWA). Lubbock is a member city of
the CRMWA. Water supplied from CRMWA is a blend of surface water and
groundwater. The surface water source is Lake Meredith and the ground water source is
the CRMWA well field located in Roberts County. The supply capacity of this system to
Lubbock is 42 million gallons per day (MGD). This blended supply is treated at the
Lubbock North Water Treatment Plant in Lubbock. The treatment plant is a conventional
water treatment plant, and treats water for the city and for six other CRMWA southern
division member cities: Slaton, Tahoka, O'Donnell, Lamesa, Levelland and Brownfield.
CRMWA supplies the raw water to these cities.
(b) The city provides water treatment services only to these cities. These cities
reimburse Lubbock for their respective portions of the water treatment cost. CRMWA
operates a 250 million gallon capacity raw water reservoir located near the treatment
plant. The city owns and operates a 400 million gallon raw water storage reservoir
located adjacent to the CRMWA reservoir. This reservoir is used during summertime
peak water use periods to supplement the normal supply from CRMWA. Its peak supply
capacity is 25 MGD.
(c) During 2014, approximately 20% of the city's annual water usage will be
supplied from a well field located in Bailey and Lamb Counties, which is owned and
operated by the city of Lubbock. This well field is commonly referred to as the Bailey
County Well Field (BCWF), and is made up of 165 production wells. All groundwater
from this source is treated at a central location in the well field. Disinfection is the only
treatment required for this source. The supply capacity of this system is 40 MGD.
(d) During 2014, approximately 20% of the city's annual water usage will be
supplied from Lake Alan Henry located 60 miles southeast of Lubbock in Garza and Kent
Counties. The supply capacity of this system to Lubbock is 15 MGD. The water pumped
from Lake Alan Henry is treated at the Lubbock South Water Treatment Plant near
Lubbock.
(e) The city water distribution system contains approximately 1,471 miles of
pipeline mains, 12 pump stations, 12 ground storage tanks totaling 64.5 million gallons, 4
conventional elevated storage tanks totaling 4.15 million gallons, and the BCWF pipeline
that functions as an unconventional elevated storage system totaling 11.0 million gallons.
(f) The city sells water on a wholesale basis to six separate public water supply
systems, the City of Shallowater, Lubbock Reese Redevelopment Authority, Lubbock
County Water Control & Improvement District No. 1 (also known as Buffalo Springs
Lake community), the Town of Ransom Canyon, the City of Littlefield, and the City of
New Deal. The water is supplied to the City of Littlefield only for infrequent emergency
use. The water supplied to the City of New Deal is water purchased from the City of
Slaton by the City of New Deal and delivered through the City of Lubbock water
distribution system, for which Lubbock charges only a delivery fee.
SECTION 3. THAT Section 22.08.034 of the Code of Ordinances, City of
Lubbock, Texas, is hereby amended to read as follows:
Sec. 22.08.034 Conservation goals
(a) The city's water conservation goals are to:
(1) Provide an adequate supply of suitable treated water to meet the needs of its
retail and wholesale customers; and
(2) Encourage its wholesale customers to adopt and implement water conservation
plans that will reduce their per capita water use rates.
(b) The city's wholesale customer water conservation program is predicated on
the fact that the implementation of conservation measures must occur largely at the local
level. Due to this fact, the city's wholesale program is focused on encouraging and
supporting initiatives by its wholesale customers.
(c) TCEQ rules require that water conservation plans contain specific,
quantifiable five- and ten-year goals for use in gallons per capita per day. The goals
established as part of this plan are not enforceable. The gpcd calculation, as defined by
TCEQ, is the total average daily amount of water diverted or pumped for treatment by
potable uses divided by the population served.
(d) In order to set a per capita goal for municipal water conservation, baseline per
capita water use was determined from the average per capita water use from 2009 to 2013
as determined by the city. In order to determine these values, the city uses total water
pumped from all sources divided by the estimated city population as determined by the
city's planning department. This resulted in an average value reflecting both wet and dry
years. The average per capita use from 2009 to 2013 was 153 gpcd with a high of 178
gpcd in 2011 and a low of 140 gpcd in 2009. This average per capita use rate is less than
the target rate of 172 gpcd recommended by the Llano Estacado Regional Water Planning
Group, but greater than the target rate of 140 gpcd recommended by the state water
conservation task force. The water conservation task force recommends a one percent per
year reduction until the target of 140 gpcd is reached; however, in light of the fact that the
city has already achieved a significant conservation response, the goals for this plan were
developed utilizing a 0.5% per year reduction in per capita water use. This results in a per
capita goal for year 2019 of 150 gpcd and a year 2024 goal of 147 gpcd. This reflects a
reduction of 0.5% per year from the 155 gpcd in 2013. .
(e) This methodology is similar to that used in the city's previous water
conservation plan adopted in 2010. The former and current plans use a 0.5% per year
reduction in per capita water use goal. The new goals established under this revised plan
are similar to those previously established.
(f) In addition to the per capita water use goal above, the city has set a maximum
water loss water goal of 10% for the retail water delivery system for both 2019 and 2024.
This would correspond to a loss rate of 15 gpcd in 2019 and 14.6 gpcd in 2024. This goal
is a benchmark established by the TCEQ for water loss.
SECTION 4. THAT Section 22.08.035 of the Code of Ordinances, City of
Lubbock, Texas, is hereby amended to read as follows:
Sec. 22.08.035 Metering water diverted from the source of supply
The city meters the amount of raw water pumped from the BCWF, Lake Alan Henry, and
from the CRMWA supply using meters that are maintained to record flow with an
accuracy of plus or minus 5.0%. The amount of water delivered to each wholesale water
customer is also metered by the city.
SECTION 5. THAT Section 22.08.079(l)(c)(vi) of the Code of Ordinances, City
of Lubbock, Texas, is hereby amended to read as follows:
(vi) New plant material may be irrigated on a more frequent basis until the new plant
material is established as defined in section 22.03.133(a)(4) related to the operation of
irrigation systems.
SECTION 6. THAT Section 22.08.079(2)(c)(iv) of the Code of Ordinances, City
of Lubbock, Texas, is hereby amended to read as follows:
(iv) Water customers will refrain from or significantly limit aesthetic and non-essential
water use as defined in section 22.08.003. Water shall not be used to wash down hard
surfaced areas, including, without limitation, sidewalks, parking lots, gutters, and patios.
Water shall not be used for dust control. However, water may be used for construction or
to clean surfaces for painting.
SECTION 7. THAT Section 22.08.079(2)(c)(vii) of the Code of Ordinances, City
of Lubbock, Texas, is hereby amended to read as follows:
(vii) New plant material may be irrigated on a more frequent basis until the new plant
material is established as defined in section 22.03.133(x)(4) related to the operation of
irrigation systems.
SECTION 8. THAT Section 22.08.079(3)(c)(iii) of the Code of Ordinances, City
of Lubbock, Texas, is hereby amended to read as follows:
(iii) Water customers will refrain from aesthetic and non-essential water use as defined in
section 22.08.003. Water shall not be used to wash down hard surfaced areas, including,
without limitation, sidewalks, parking lots, gutters, and patios. Water shall not be used for
dust control. Pools and hot tubs may not be filled or drained and refilled.
SECTION 9. THAT Section 22.08.079(4)(c)(i) of the Code of Ordinances, City
of Lubbock, Texas, is hereby amended to read as follows:
(i) All aesthetic and non-essential water use, as defined in section 22.08.003, including
landscape irrigation use, is prohibited except where necessary to protect the health,
safety, and welfare of the public. No new landscape material may be installed.
SECTION 10. THAT, unless otherwise provided herein, a violation of any
provision of this Ordinance shall be deemed a misdemeanor punishable as provided by
Section 1-4 of the Code of Ordinances of the City of Lubbock.
SECTION 11. THAT should any paragraph, section, sentence, phrase, clause or
word of this Ordinance be declared unconstitutional or invalid for any reason, the
remainder of this Ordinance shall not be affected thereby.
SECTION 12. THAT the City Secretary of the City of Lubbock is hereby
authorized and directed to cause publication of the descriptive caption of this Ordinance
as an alternative method provided by law.
SECTION 13. THAT this Ordinance shall become effective, except as may
otherwise be provided herein, from and after its publication as provided by law.
