Wastewater Collection and Treatment Project in Camargo, Tamaulipas.

Status: Completed Construction


Solid waste collection coverage in Frontera Ribereña is approximately
94% for the five municipalities. An estimated 85 tons of solid waste are
collected daily. However, the collected waste is improperly disposed of
in substandard, open-air dumpsites, contaminating the region’s soil and
groundwater resources, as well as creating disease-breeding and vectorinfested sites. An estimated 645,000 tons of accumulated waste has been
deposited at these sites over the past half century.

In addition, these sites are subject to recurring, uncontrolled fires that
produce airborne toxins, including dioxins from burning plastics and
tires. Smoke from these fires affects the air quality of neighboring
communities, including those across the border, such as Rio Grande City,

Moreover, because the municipalities have lacked adequate solid waste
disposal facilities for years, several illegal dumpsites have emerged
within these communities, creating additional disease-breeding and
vector-infested sites, increasing exposure to gastrointestinal, parasiterelated and respiratory illnesses throughout the region.

Initially, each municipality planned to build a separate landfill in order to
comply with Mexican federal standards. However, this plan was not
economically feasible, so the five municipalities decided to implement a
regional landfill. To that end, they purchased the land for the landfill and
created the utility, Servicios de Limpia de la Frontera Ribereña
Tamaulipeca, to operate the facility.


  • The Project consists of the following main components:
    Construction of a regional sanitary landfill in the municipality of
  • Construction of two direct-dump transfer stations, one in the
    municipality of Mier and the other in the municipality of Gustavo
    Díaz Ordaz;
  • Acquisition of equipment for garbage collection and the operation
    of the landfill and transfer stations, as well as the transportation
    of solid waste from the transfer stations to the landfill; and
    Closure of the five existing open-air dumpsites.


Implementation of the Project will prevent health and environmental
problems associated with the inadequate disposal of solid waste,
including exposure to gastrointestinal, parasite-related and respiratory
illnesses, for the residents of Frontera Ribereña, as well as in Starr
County, Texas. In particular, closure of the current open-air dumpsites
will eradicate the breeding grounds of rodents and other vectors, as well
as eliminate recurring fires at such sites. Moreover, by sharing a single
facility, the municipalities were able to reduce capital costs by
approximately 18%, as well as optimize operation and maintenance
