Wastewater Collection and Treatment Project in Praxedis G. Guerrero, Chihuahua

Status: Completed construction


At certification time: The JMAS provided wastewater collection service to 70% of the residents of Praxedis G. Guerrero. The collection system was not able to handle the existing wastewater flows, some of the lines in the system had inadequate slopes resulting in low flow and inadequate velocities. Wastewater treatment was not available.


The purpose of the Project was to eliminate exposure to untreated wastewater by improving and expanding the wastewater collection system and the construction of a wastewater treatment plant, contributing to the reduction of water pollution and the risk of water‐borne diseases.


The project consisted of the expansion and rehabilitation of the wastewater collection system and the construction of a wastewater treatment plant based on a stabilization pond system for the community of Praxedis G. Guerrero, Chihuahua.
