3
General Aspects
  • Project Location
  • City of La Joya is located in Hidalgo County,
    Texas west of McAllen. The community is 5 miles
    north of the U.S./Mexican Border.

4
General Aspects
  • State of Existing WWTP and Collection System
  • Originally constructed in 1982, the WWTP is a
    no-discharge pond facility.
  • The system includes a WWTP with a capacity of
    0.175 MGD and consists of two lagoons, two
    stabilization ponds, one holding pond, one
    submersible pump and wet well for irrigation and
    re-circulation purposes and one 5.24-acre
    irrigation field.
  • The WWTP includes five storage ponds with total
    capacity of 27.8 acre-feet for storage of treated
    effluent prior to evaporation and irrigation.
  • It should be noted that the renewal permit
    requires 28.9 acre grassland drainage area.
  • Currently in poor condition, the WWTP operates
    well-above its designated capacity.
  • The Citys wastewater collection system consists
    of 8-inch gravity sewer pipe, 4-inch to 6-inch
    force main, and 9 lift stations, with most of the
    gravity sewer mains flowing at full capacity and
    not able to accept additional flow.
  • Concerns Currently violating renewal permit
    requirements with only 5.2 acres of grassland
    available for disposal. Additional expansion is
    required to address capacity demands.

5
General Aspects
  • Proposed Wastewater Treatment System Improvement
    Project
  • Continued use of the existing WWTP requires
    acquisition or lease of additional disposal land
    under the current TCEQ no-discharge permit is
    still needed.
  • Expansion/Replacement of existing WWTP in order
    to comply with TCEQs permit, which requires the
    City to commence construction of additional
    treatment facilities after reaching 90 percent of
    capacity.
  • The WWTP will be constructed to accommodate
    additional flow from the expanding school
    district and from the planned extension of
    wastewater services to outlying colonias of
    Tierra Blanca, Havana and Penitas.
  • The City agrees with the existing technical
    studies recommendation to construct a new
    conventional WWTP rather than expanding the
    existing WWTP because of land requirements of
    that technology. The proposed alternative for the
    ww treatment will implement an activated sludge
    process consisting of oxidation ditches,
    clarifiers, chlorine disinfections, and sludge
    processing facilities, requiring approximately
    9-acres and treat 1.57 MGD.
  • Improvements to the existing wastewater
    collection system, including the rehabilitation
    of some existing lift stations, collection lines,
    manholes, laterals, extension of new service to
    the outlying colonias and household connections.

  • USDA City applied for funding for construction
    of lift stations in 2001 (currently awaiting
    completion of review by USDA).
  • CDBG grant funding provided in 2001 to prepare
    plans, specs and estimates to re-certify
    pond-lining and repair areas of erosion of the
    WWTP stabilization and holding ponds.
  • TWDB the City has applied for funding for the
    proposed project.
  • No prior BECC or NADB assistance.
  • 2001 Environmental Information Document.
  • Drafted Category A, B and C planning documents
    per TWDB.

Environmental and Human Health Indicators
  • Human Health Indicators
  • The limitations of the WWTP pose a direct threat
    to the health and safety of the residents of La
    Joya, given the potential health risks that can
    be derived from groundwater contamination due to
    higher application rates.
  • The residents of Tierra Blanca, Havana and
    Penitas currently utilize septic tanks and drain
    fields. Failure of these systems represents a
    public risk.
  • Most of these on-site systems do not meet TCEQ
    On-Site Sewage Facilities design requirements,
    with most residential lot sizes with less than
    0.5 acres or multiple homes on a single lot.

9
Environmental and Human Health Indicators
  • Human Health Indicators
  • The expansion of the Citys WWTP and the
    rehabilitation of the existing collection system
    will address several human health and
    environmental concerns of the residents of City
    of La Joya and outlying colonias of Tierra
    Blanca, Havana and Penitas, which currently
    utilize septic tanks and drain fields.
  • Although existing statistics are not specific to
    the City of La Joya, the Texas DOH has indicated
    that cases of Cryptosporidiosis and Amebiasis
    have been reported in Hidalgo County. The number
    of cases per 100,000 people are as follow

10
Environmental and Human Health Indicators
  • Environmental Indicators
  • The poor conditions and under sizing of the
    existing WWTP may have a significant
    environmental impact on the groundwater and air
    quality of the area.
  • Overflow conditions and exposed wastewater
    accumulated at the surface of land disposal areas
    due to higher application rates can create a pest
    and odor nuisance for the community of La Joya.
  • Groundwater contamination may occur due to
    improper lining of the stabilization ponds and
    higher land application rates on designated
    disposal areas.
  • The proposed project will bring positive
    improvements to the general environment of the
    City of La Joya are by eliminating the
    environmental impacts that can be caused by the
    current wastewater disposal practices and
    systems deficiencies.

11
Environmental and Human Health Indicators
  • Compliance with Environmental Norms Regulations
    Including Violations
  • The City received a notice of violation on
    January 5, 2000, by TCEQ, regarding the Citys
    failure to commence additional construction
    planning of the WWTP after reaching 90 percent of
    capacity for three consecutive months.
  • Previous TCEQ violations included the need to
    repair stabilization and holding pond
    embankments, failure to provide an audio-visual
    alarm system for all lift stations and failure to
    submit a permit application within the
    appropriate time before the expiration date of
    the effective permit.
  • The City needs to improve the existing wastewater
    distribution system to resolve the overflow
    conditions in pipelines due to the increase in
    flow by rainfall events, causing significant
    increase to influent at the WWTP.

    operators will be needed, specifically with B
    and C certifications. Operator training
    recommended.
  • Management Capabilities working with the Tejeda
    Center for continued assistance.
  • Governance Recommend elected official training
    and development of manuals.

22
Technical Approach,Objectives and Funding Plan
  • Potential Obstacles
  • Inter-local agreement are complete with the City
    of Penitas to allow the City to provide
    wastewater treatment within the Penitas
    wastewater CCN (No. 20794), further obstacles for
    this community are not anticipated to meet the
    proposed project objectives.
  • La Joya WSC has agreed to decertify a portion of
    CCN to provide an opportunity for the City to
    certify this area. Further obstacles are not
    anticipated on this issue.
  • USDA has not participated in RAP and is a
    potential funding source for the project.
    Efforts must continue to be made to bring this
    agency to the table. Modifications to planning
    documents be required.
  • Potential obstacles may exist because of the
    public perception problems encountered during the
    recently certified project with La Joya WSC.
  • The final WWTP site selection process should take
    into account significant public outreach. A site
    is recommended in the existing planning
    documents, public outreach must be extensive to
    comfort the response of the community.
