Background

JMAS provides drinking water service to approximately 100% of the homes in Camargo 18,357 residential connections. Approximately 96% of the homes in the urban area are also connected to the wastewater collection system, which operates by gravity. The existing connections generate approximately 80 liters per second (lps) or 1.8 million gallons per day (mgd) of wastewater, which is conveyed to the Camargo Wastewater Treatment Plant (WWTP) to receive treatment through a system of stabilization lagoons. The WWTP has an installed capacity of 140 lps (3.2 mgd), which is sufficient to treat current and future flows. The effluent produced by the WWTP complies with its discharge permit and Mexican federal regulations.  A portion of the treated effluent is reclaimed for agricultural irrigation and the rest is discharged to the San Pedro River.

Description

The project consists of the construction of a wastewater collection system, including the installation of approximately 2,900 meters (9,515 feet) of 20-cm (8-inch) diameter polyvinyl chloride (PVC) pipe and up to 131 yard-line connections. The current on-site systems will also be decommissioned.

Benefits

The project will reduce human health risks associated with waterborne diseases and the potential for groundwater contamination by providing first-time access to wastewater collection and treatment services for 131 homes and decommissioning their current on-site wastewater disposal systems. The project is expected to collect and treat approximately 0.96 lps or 21,871 gallons per day (gpd) of wastewater.
