Rehabilitation of Colector Poniente: Segment 1A

Status: Pre-construction

Background

CESPT has developed a Comprehensive Wastewater Treatment and Reuse Plan to reduce untreated wastewater discharges to the Pacific Ocean, improve the management of treated wastewater discharges to the Tijuana River basin, increase the use of treated water through groundwater replenishment, address sludge disposal, prioritize infrastructure development and establish a financial strategy. The immediate actions proposed by the plan include the rehabilitation of critical wastewater collectors. CESPT is already completing construction on three segments of the Colector Poniente, which will reduce the risk of discharges to the Tijuana River.  

Description

The project consists of the rehabilitation of approximately 1,874 linear meters (6,146 ft) of the Colector Poniente. 

Objective

The purpose of the project is to improve wastewater collection and conveyance infrastructure for up to 23,506 existing residential wastewater connections and to reduce the risk of pipeline failures, which would prevent approximately 177 liters per second (lps) or 4 million gallons per day (mgd) of untreated or inadequately treated wastewater discharges, thereby helping reduce water pollution and the risk of waterborne diseases, as well as transboundary wastewater flows into the United States.
