JMAS provides drinking water service to approximately 98% of the homes in Ojinaga through 11,389 residential connections, while approximately 85% of the homes in the urban area are connected to the wastewater collection system. Those homes not connected to the centralized system are sparsely located south of the city, where extending service may not be feasible. The wastewater collection system operates by gravity and relies on one lift station to convey approximately 87.6 liters per second (lps) or 2.0 million gallons a day (mgd) of wastewater to the Ojinaga Wastewater Treatment Plant to receive treatment through a system of stabilization lagoons. The plant has an installed capacity of 140 lps (3.2 mgd).
The project consists of replacing approximately 27,688 meters (90,840 feet) of PVC pipe with dimeters ranging from 8 inches to 12 inches, construction of 239 manholes and rehabilitation of the service connections to 1,700 residences.
The rehabilitated infrastructure will improve wastewater collection services for 1,700 existing residential connections by reducing the risk of pipeline failures that cause sewage overflows onto local streets and contaminate surface and groundwater. Specifically, the project will help protect public health and the environment by preventing approximately 12.3 liters per second (lps) or 281,000 gallons per day of wastewater discharges. Even more importantly, the project will help prevent contamination of the West Texas Bolson Aquifer, which supplies drinking water to Ojinaga and to Presidio, Texas.
