The residents in the Mines Road and SH 359 planning areas are not provided water service by any water purveyor. Some residents utilize individual wells that only produce non-potable water. Most lots within the planning areas are not large enough (considering the existence of numerous dwellings per lot) to accommodate the construction of on-site sewage facilities and private water wells while still maintaining the minimum separation requirements. Residents must rely on external sources for their potable water needs.
The residents in both planning areas do not have access
to a centralized wastewater system. All
of the residents utilize some type of on-site system as their primary means of
wastewater disposal. As a whole, these
on-site systems are substandard and include undersized and poorly constructed
septic systems, pit privies, and open cesspools. Numerous makeshift gray water systems are also present in both
planning areas, which discharge laundry and kitchen wastewater to the ground
surface in an effort to minimize the hydraulic loading on the existing septic
tank systems.
The
current number of households and population for the fifteen colonias in 2000 is
787 and 3,725, respectively. The
proposed water and wastewater improvements are designed to provide adequate
water and sewer service to the Year 2016 for 1,193 households and 5,649 colonia
residents.
In
addition to the Texas Water Development Board (TWDB) – Economically Distressed
Areas Program (EDAP) funding, additional funding for the project will be
obtained from Webb County and the North America Development Bank
(NADBank). Using NADBank as a source of
funds for the water and wastewater improvements was recognized due to the TWDB
limitations associated with the cost per connection. Additionally, the TWDB
made a determination that On-Site Systems could be used for all of the colonias
in the Mines Road Planning Area; however, a conventional wastewater collection
and treatment system is recommended for four of the five Mines Road colonias
for long-term sustainability.
Obtaining
a source of funding from NADBank is critical to ending the continuing health
risk posed by the present use of inadequate septic tanks or cesspools as noted
by the Texas Natural Resources Conservation Commission (TNRCC) Nuisance Finding
(Appendix C). Adding new connections to
the utility system will also provide additional revenues to meet the debt
service obligations incurred by the TWDB-EDAP Project (approximately $1.5
million loan to City of Laredo).
The City of Laredo defined the concept and the monetary requirements for implementation of the water and wastewater improvements. The outline of the needs and the funding required was submitted as a Step 1 Format to the Border Environment Cooperation Commission (BECC) on April 8, 1999. A summary of the proposed project costs by sources and uses is shown in Table 1.

The City of Laredo and Webb County received approval from the TWDB Finance and Policy Committee in April 2000 for funding of $14,738,837 for proposed water and wastewater improvements under the EDAP. Approval of the EDAP funding by the full BOARD is scheduled for July 2000 after the issuance of a FONSI by the Environmental Protection Agency. The project area includes two planning areas, Mines Road and SH 359, comprised of a total of fifteen (15) economically distressed subdivisions, or colonias. The colonias are located outside the city limits but are within the City’s ETJ. An Interlocal Agreement, included in Appendix E, between the City of Laredo and Webb County states both the City and the County find it appropriate that the City assume responsibility for the extension of water and sewer services into the project area.
A. General Project
Description
The
City of Laredo is located in Webb County, Texas directly across of the Rio
Grande River (Rio Bravo) from Nuevo Laredo, Tamaulipas, Mexico. The City and County are proposing a joint
colonias improvements project consisting of water and wastewater service to 15
colonias located outside of the City limits but within the City’s ETJ. The colonias are within the two planning
areas of Mines Road and SH 359 as shown in Figure
1, Project Areas Map. The planning
areas consists of the following colonias:
Mines Road Planning Area:
Los
Corralitos
Ranchitos
Penitas West
Los
Minerales
Antonio
Santos
Ranchitos
IV / Los Minerales Annex
The
proposed water distribution improvements for Mines Road consist of 80,000
linear feet of 8-inch water line, 18,000 linear feet of 10-inch water line, one
booster station, and a 50,000 gallon ground storage tank. The City owns a Water Treatment Plant with
capacity available to serve the colonia areas.
The
proposed wastewater collection system improvements for Mines Road consist of
68,500 linear feet of 8-inch gravity sewer, 3 lift stations, 5,200 linear feet
of 4-inch force main, 6,350 linear feet of 6-inch force main, and 32 On-Site
Sewage Facilities. A new 0.125 MGD
Package Wastewater Treatment Plant is proposed for the Mines Road area.
SH 359 Planning Area:
Old Milwaukee San
Carlos Phase I
Los
Altos San
Carlos Phase II
Los
Tanquecitos I Ranchitos
359 East
Los
Tanquecitos II Laredo
Ranchettes
D-5
Acres Pueblo
Nuevo
The proposed water distribution improvements for SH 359 consist of 105,500 linear feet of 8-inch water line, 51,000 linear feet of 12-inch water line, 30,100 linear feet of 16-inch water line, a 250,000 gallon elevated storage tank, a 200,000 gallon ground storage tank and booster station. The City owns a Water Treatment Plant with capacity available to serve the colonia areas.
The
proposed wastewater collection system improvements for SH 359 consist of 98,800
linear feet of 8-inch gravity sewer, 6,500 linear feet of 12-inch gravity
sewer, 24,150 linear feet of 15-inch gravity sewer, 3 lift stations, 2,200
linear feet of 3-inch force main, and 11,500 linear feet of 6-inch force
main. Wastewater flows generated by
colonias will be conveyed to the City of Laredo’s proposed Chacon Creek
Interceptor with ultimate treatment at the City's Southside Wastewater
Treatment Plant. A 15-inch trunk line
along the Texas Mexican Railroad easement is proposed to convey the wastewater
flows from the colonias in the SH 359 study area to the interceptor. The interceptor began construction in 1999
and is expected to be completed in 2001.
The Southside WWTP has available capacity to serve these colonia areas.
The
proposed colonia water and wastewater improvements are to be funded by
TWDB-EDAP, Webb County and NADBank funds.
B. Compliance
with BECC criteria
B.1. General Information
The
City of Laredo and Webb County Joint Colonias Improvement Project consists of
water distribution improvements and wastewater collection and treatment system
improvements. A brief discussion of
each is presented below.
Water Supply and
Treatment. Adequate facilities are
currently not available for the Mines Road and SH 359 planning areas. The City of Laredo obtains its water supply
from the Rio Grande River, and it is the only Certificate of Convenience and
Necessity (CCN) holder and nearby supplier of facilities that are adequate to
serve the colonias in accordance with state design criteria for water and
wastewater systems. According to the
TNRCC, the City's total combined water rights of 40,596 acre-feet/year
(approximately 36.24 mgd on an average daily basis) are held under Certificate
of Adjudication No. 23-3997A.
The City of Laredo has one water treatment facility in operation, the Jefferson Street Water Treatment Plant with a capacity of 60 MGD. According to the City of Laredo, the water treatment system average daily demand is estimated to be 25 mgd of the 60 mgd capacity (42%) with a maximum daily demand estimated to be 48 mgd. Based on 36,598 connections, average daily demand is estimated to be 683 gpd/connection with maximum daily demand estimated to be 1,311 gpd/connection.
Additional
water use information was obtained from the water use survey conducted by the
TWDB Planning Division. The TWDB
municipal water use projections include residential, apartment, and commercial
flows, while attempting to exclude industrial, agricultural, and irrigation
water requirements. Utilizing
population estimates developed from the TWDB most likely series population
projections, the City of Laredo population for 1995 was estimated to be
147,286. This results in the average
daily demand of 182 gpcd for the City of Laredo only.
Water
demand projections represent the minimum state requirements set by TNRCC of 0.6
gpm/connection for average daily flow demands. Water treatment plant capacity
requirements are based on a peak daily of 1.6, which is based on an annual
basis of the ratio of maximum daily demand to average daily demand determined
from the 1995 TNRCC Sanitary Survey of the City's water system.
According
to data provided by the City of Laredo Utility Department the average monthly
residential water consumption per connection is approximately 15,000 gallons.
The average household size for the Mines Road and SH 359 planning areas was
determined to be 4.55 persons and 4.80 persons, respectively. This results in an average daily demand of
108 gpcd for the Mines Road planning area and 102 gpcd for the SH 359 planning
area. For the purposes of this study,
the average daily residential demand for both planning areas will be based on
an average usage of 104 gpcd.
Average
daily water demand projections and water plant capacity requirements through
the year 2016 for the Mines Road and SH 359 planning areas are summarized in Table 2. The projected average daily water demand and water plant capacity
requirements for the Mines Road planning areas for the year 2016 are estimated
to be 144,768 (gallons per day) gpd and 231,629 gpd, respectively. The projected average daily demand and
required water treatment plant capacity for the year 2016 for the SH 359 study
area are estimated to be approximately 442,728 gpd and 708,365 gpd,
respectively.
In
order to evaluate the City of Laredo’s ability to provide water to the Mines
Road and SH 359 planning areas, projections for the In-City water demand were
developed. The City of Laredo water
treatment system average daily demand is estimated to be 25 million gallons per
day (mgd), which is approximately 42% of the total existing treatment capacity
of 60 mgd. The completion of the
improvements to the Jefferson Street Facility will increase the total treatment
capacity to approximately 60 mgd. A
summary of average and maximum daily water demand projections through the year
2016 for the City of Laredo and the Mines Road and SH 359 planning areas are
summarized in Table 3. In order to meet the projected water
treatment plant requirements of 80 MG for the year 2016, the City plans to
expand the plant by an additional 20 mgd.
The
water system improvements will require an equity buy-in to the existing City of
Laredo 60 mgd Jefferson Water Treatment Plant.
The City will also need to acquire an additional 658 Acre-Feet of
municipal water rights from the TNRCC’s Rio Grande Watermaster. The
purchase of the equity buy-in for the existing Water Treatment Plant capacity
and water rights has been funded by the TWDB.
Furthermore, the TWDB has agreed to purchase existing water rights held
by the City of Laredo. Subsequently, no
impact to water transfers or surrounding water supplies would be expected.

Proposed
improvements to provide water service to the Mines Road planning area include
the construction of a water distribution system within each of the
colonias. Table 4 shows the projected construction costs for the water
distribution system within each individual colonia with a total projected
construction cost estimated to be approximately $739, 575.
The
City of Laredo water distribution system is to be expanded to the planning area
by extending a 10-inch waterline along FM 1472 from La Bota to FM 3338. The 10-inch line would supply two 8-inch
lines connected to the distribution system for the colonias. One 8-inch line would extend along FM 3338
from FM 1472 to Ranchitos Penitas West.
The other 8-inch line would extend along FM 1472 from FM 3338 to Los
Minerales and the surrounding colonias.
A 50,000 gallon ground storage tank and booster station are proposed for
the Mines Road area for pressure maintenance. Table 5 shows the costs to extend the City of Laredo waterlines to serve
the Mines Road planning area is approximately $1,103,550. The proposed water distribution improvements
are shown in Figure 2 (Mines Road.)
Proposed improvements to
provide water service to the SH 359 planning area include the construction of a
water distribution system within each of the colonias. Table 6
shows the projected construction costs for the water distribution system within
each individual colonia to be approximately $1,902,972.
The proposed colonia
distribution systems would be supplied using City water by extending a water
line from the City limits to Pueblo Nuevo.
These water line extensions, as shown in Figure 3, would include a 16-inch water line from the City's South
Elevated Storage facilities to the Old Milwaukee colonia. The remainder of the colonias would be
served through a series of proposed 12-inch water lines.
The water modeling effort
completed by TC&B also recommended the following facilities be included in
the proposed water improvements in order to adequately serve the colonias
within the SH 359 planning area. These
improvements include a 200,000 gallon ground storage tank and a 250,000 gallon
elevated storage tank, combined with a booster pump station located at D-5
Acres, with at least two pumps having a combined capacity of 1,000 gpm, and
rated at 195 feet of total dynamic head.
The total estimated construction costs of the proposed extensions and
facilities is estimated to be $2,548,350 as itemized in Table
7 (Costs are exclusive of land acquisition
costs.)
The water distribution
improvements are shown in Figure 4 (SH 359.)
