Wastewater Collection, Treatment, and Reuse Project for Colonia Anapra, Ciudad Juarez, Chihuahua, Mexico

Status: Completed Construction

Background

In 2007 the JMAS had already provided access to wastewater collection services to most of the residents of Anapra. However, because there was not a wastewater treatment plant, JMAS did not allow the households to connect to the collection system, therefore, residents continued disposing the wastewater through saturated latrines and some illegal connections to the sewer system that discharged directly onto the street, creating serious health hazards to the area residents. In addition, due to the topography of the area, runoff flowed from south-to-north towards Sunland Park, NM. Since the runoff was very likely to contain untreated wastewater, addressing this environmental problem was a high priority for both Mexican and US governments.

Description

Eliminate exposure to untreated wastewater in unserved areas through the construction of the wastewater collection system, construction of a new WWTP, and the construction of a reclaimed wastewater system; contributing to the reduction of groundwater pollution and the risk of water-borne diseases.

Benefits

This project consisted of the the construction of the wastewater collection system, a wastewater treatment plant (WWTP), and a reclaimed wastewater system. The lift station includes biological odor control measures and the WWTP consists of a secondary treatment process (activated sludge). The reclaimed wastewater system includes a distribution network for landscape irrigation purposes and conveyance to divert excess flow to the Benito Juarez reservoir.

Project Financing

Total Project Cost US 6.24M
NADB Funding US 0.44M - NADB Loan

Results Measurement

Results are measured upon completion of the project through a closeout process that assesses project performance within 6-12 months after completion, as well as the achievement of the goals and objectives established at the time of project certification and financing approval.

Outcomes

Provide access to wastewater collection and treatment services Reduce untreated wastewater discharges. Decrease demand on water resources.
