Environment Cooperation Commission
Wastewater Collection System Rehabilitation and
Improvements Project
Tijuana, Baja California
1.
Project Type
The project consists of the rehabilitation of
approximately 131,000 meters of wastewater collection lines, which represents
approximately 7.5% of the total length of the city’s system.
2. Project Location
The
project is located in the city of Tijuana in the state of Baja California. All the components of the project are
located within the watershed of the Tijuana River, which flows into the United States
and reaches the Pacific Ocean through the Tijuana Estuary. According to the 2000 Census, Tijuana has a
population of 1,210,820. The Consejo
Estatal de Población (CONEPO) has official population projections through
the year 2010. It is expected that
Tijuana will reach a population of 1,424,426 by that year. If the population growth rate of 2.1% per
year utilized by CONEPO for the period 2005-2010 is extrapolated for the next
decade, a population projection of 1,755,138 for the year 2020 is obtained.
3. Project Description and Tasks.
The proposed project is composed of 50 specific projects for the
rehabilitation of sewer laterals, collectors and sub-collectors. Overall, 131,000 meters of sewer lines will be
rehabilitated with lines varying in diameter from 20 to 122 cm. Of the 50
projects, 36 involve the rehabilitation of laterals, 7 the rehabilitation of
collectors, 6 the rehabilitation of sub-collectors, and 1 the rehabilitation of
an interceptor.
The following table summarizes all 50 proposed projects.
