General Aspects
Project Location
Marfa is located in
Pecos County on
Highway 90 between
Valentine to the
Northwest and Alpine to
the East.
General Aspects
Existing Water Supply and Distribution System
 Water is supplied from three wells at a central site to a 1 MG
Ground Storage Tank
 Booster Pump Station at central site pumps chlorinated water to
the system and an Elevated Storage Tank
 Distribution system consists of three pressure zones made up of
1-inch to 8-inch water lines
 Distribution system includes two booster pump stations, a stand
pipe and ground storage tanks
General Aspects
Water System Problems and Concerns
 Water does not meet secondary drinking water quality standards
for fluoride
 Undersized and dead end lines resulting in:
 Low pressure areas
 Low chlorine residual
 Fire flow concerns
 Concerns: Compliance with TCEQ regulatory requirements for
fluoride, chlorine residual, low pressures and fire flows
General Aspects
Proposed Water Supply and System
Improvements
 Water supply improvements to meet TCEQ regulatory
requirements for fluoride
 Distribution system improvements to upsize and loop
lines in problem areas to alleviate pressure, chlorine
residual and fire flow concerns
General Aspects
Existing Wastewater Collection &
Treatment System
 WWTP consists of influent meter, bar screen, 2 Imhoff
tanks and 2 sludge pits and 2 sludge drying beds
 Effluent Disposal by irrigation of 62 acres of non-public
access pasture land
 Permitted flow = 0.120 MGD Average Flow = 0.08 MGD
 Collection system comprised of 4-, 6-, 8- and 10-inch lines
and two sanitary lift stations
 Portions of system date back to late 1920’s
General Aspects
Wastewater System Problems and
Concerns
 Outdated, substandard technology – Imhoff Tanks
 74 Year old WWTP
 Effluent storage pond required by TCEQ – Condition of
Permit
 Undersized, substandard lines – old, 4-inch VC pipelines
 Line condition suspect – deterioration, root intrusion,
surcharged manholes.
General Aspects
Proposed Wastewater System
Improvements
 WWTP Effluent Storage Pond
 WWTP Technology Upgrades
 Relief or replacement of capacity deficient, problem area
sewer lines
General Aspects
Total Estimated Cost
Budget for design and construction pending
further definition of the needs, alternatives
analysis and project development.

 1977 - Water and Sewer System Facilities Plan
 1970 – City of Marfa Comprehensive Plan
Environmental and
Human Health Indicators
Human Health Indicators
 Fluoride levels close to 3 times the recommended level
can cause dental and skeletal fluorosis.
 Low or no chlorine residuals in dead end lines can lead to
illness.
 Specifically, improvements to the water supply quality
will address concentration of fluoride, chlorine residual
and minimum pressures.
Environmental and
Human Health Indicators
Environmental Indicators
 Improvements to the water system are necessary to meet fire
protection demands, which poses a direct threat to the health and
safety of the City of Marfa residents.
 The City’s three water wells are located on the same site such that if
one is contaminated, it could affect all three. Alternate source is
advisable.
 Correction of collection system capacity problem will help mitigate
overflows and resulting pollution.
 WWTP upgrades will result in a controllable effluent discharge to
fields.
Environmental and
Human Health Indicators
Compliance with Environmental Norms &
Regulations Including Violations
 Fluoride above secondary standard
 Substandard water and sewer lines (1- & 2-inch water and
4-inch sewer)
 Outdated WWTP technology – Imhoff Tanks
Technical Approach,
Objectives and Funding Plan
Project Objectives
 Improve water treatment and distribution
 Improve wastewater collection and treatment.
Technical Approach
 Technical Assistance needed to develop documents which
may include:
 QAPP
 Facility Plan & Environmental Information Document
 Engineering Design
 Financial Analysis
 Public Participation Program
 Rate Study

Identified Potential Funding Sources

USDA/Rural Utility Services (RUS)
 Funds tailored for rural areas with populations of less than 10,000
 Grant

Texas Water Development Board

SRF Loan

North American Development Bank (NADB)
 BEIF Grant and IDP Grant/Loan

Border Environment Cooperation Commission (BECC)
 PDAP program Grant
Technical Approach,
Objectives and Funding Plan
Institutional Capacity Building
 The project sponsor identified such needs as a capital
improvement plan, rate study and the development of public
participation programs as institutional needs.
 Additional needs may include assistance in both the
institutional and human capacity to administer the project.
 The Frank M. Tejeda Center has conducted an Institutional
Capacity Needs Assessment with the City of Marfa.
Technical Approach,
Objectives and Funding Plan
Potential Obstacles
 The project sponsor and the BECC are not aware of any legal
issues that may jeopardize the proposed project, or any
litigation problems with the current local government.
 A notable potential obstacle is the high cost of providing water
treatment to address the quality issues present in the water
basin near the City of Marfa.
 Rate modifications may also provide a potential obstacle for
receiving community support.
