Wastewater Collection and Treatment Project in Porfirio Parra, Chihuahua

Status: Completed


The collected wastewater was discharged to nine different points along the “Interceptor Drain” which eventually discharged to the Rio Grande. 12% of the population lacked wastewater collection service and wastewater treatment was nonexistent. Residents who lacked wastewater collection disposed of their wastewater using latrines and cesspools which, due to the relatively shallow water tables and the type of soil, resulted in wastewater overflows and runoffs throughout the community.


The purpose of the project was to eliminate exposure to untreated wastewater by expanding the wastewater collection and treatment systems to un served areas, contributing to the reduction of groundwater pollution and the risk of water borne diseases.


The project consisted of the construction of a comprehensive wastewater collection and treatment system to serve 100% of the community’s population. The project includes: the integration of sewer lines into a single system, the expansion of the wastewater collection system to un served areas, the construction of a lift station and a regional wastewater treatment plant (WWTP). The WWTP consists of an stabilization pond system with a treatment capacity of 0.34 MGD (Regional WWTP).
