North and South Wastewater Treatment Plants Project and Supplemental Sewerage Projects for Cd. Juárez, Chih.

Status: Completed construction

Pre-Project Conditions

JMAS had provided wastewater collection services to 80% of the residents of Ciudad Juarez, Chih. Wastewater treatment was not available. Existing services included collection of municipal wastewater and conveyance and discharge to an irrigation system drain. The drain conveyed wastewater through the irrigation system and eventually would discharge to the Rio Grande. The JMAS did not charge users for sanitation services.

Project Objective

Eliminate exposure to untreated wastewater by the rehabilitation and expansion of the wastewater collection system, and the construction of two wastewater treatment plants (North and South) to un-served areas, contributing to the reduction of water pollution and the risk of water-borne diseases.

Project Scope

This project consists of the construction of two Advanced Primary Treatment Wastewater Plants (North and South WWT Plants). The project includes grit removal, a clarifloculation treatment followed by a final chlorine disinfection process. This treatment may be modified based on the demand and wastewater quality to a biological treatment process (activated sludge through a no nitrate load). The North Plant was designed to treat 57 MGD and the South Plant as designed to initially treat 22.8 MGD. *Since this project, both facilities have been upgraded to secondary treatment.
