Agenda
General Aspects
Project LocationMarfa is located in Pecos County on Highway 90 between Valentine to the Northwest and Alpine to the East.
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
General AspectsWater 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
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
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Outdated, substandard technology – Imhoff Tanks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
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
Prior Studies:
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
Environmental and Human Health Indicators
Project Objectives Improve water treatment and distribution Improve wastewater collection and treatment.

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.

Identification of Main Stakeholders City of Marfa, Texas TCEQ TWDB North American Development Bank Frank M. Tejeda Center Border Environment Cooperation Commission United States Department of Agriculture Environmental Protection Agencies
Local Politics The City of Marfa local government is comprised of a Mayor and five
representatives. The City passed a resolution on September 5, 2000 authorizing the Mayor to seek Technical Assistance from BECC.
Public Participation
Minimum Criteria Requirements
The City of Marfa made a commitment to comply to all applicable minimum requirements for the project in compliance with the BECC’s sustainable development criteria.
11 of 14 minimum requirements will apply to the project.
