OOMAPAS-Agua Prieta provides wastewater collection and treatment services to approximately 26,518 active connections. The collection system consists of approximately 411.5 km (255.7 miles) of pipeline of various materials with diameters ranging between 4 and 24 inches. The collection system discharges to the main outfall, which runs approximately 2.5 km (1.55 miles) south, parallel to the Agua Prieta River. It conveys approximately 107 liters per second (lps) or 2.4 million gallons a day (mgd) of wastewater to the lagoon-based Agua Prieta Wastewater Treatment Plant (WWTP). The remaining 130 lps (3.0 mgd) of untreated wastewater are conveyed to two power plants to be treated and reused for power generation.
The project consists of rehabilitating approximately 2,428 linear meters (7,966 ft) of the main outfall using corrugated high-density polyethylene pipes (corrugated HDPE). Construction activities have been divided into two sections. The North section extending 1,170 linear meters (3,838 ft) is currently under construction with the funding from FONDEN. The South section extending 1,258 meters (4,127 ft) will be funded by NADB and local resources in 2021.
The purpose of the Project is to improve the wastewater collection and conveyance infrastructure for up to 26,518 existing residential connections and reduce the risk of pipeline failures and prevent approximately 237 liters per second (l/s) or 5.4 million gallons per day (mgd) of untreated or inadequately treated wastewater discharges. This action will contribute to reduce water pollution and the risk of waterborne diseases.
