Altamont Pipeline Project Draft EIR

Altamont Pipeline Project Draft EIR

The Proposed Project would entail constructing about 11-12 miles of buried potable water pipeline. Most of the pipeline would be constructed by the conventional cut-and-cover trenching method, with smaller segments constructed through microtunneling or jack-and-bore. Minimum cover over the top of the pipe would be 3-4 feet. A microtunnel boring machine would be used for portions of the alignment where it is essential to avoid surface ground disturbance or disruption of surface activities. The pipeline would be graded for gravity flow. It would be up to 48 inches in diameter, and would accommodate a normal peak capacity of 42 MGD with fluctuations up to 46 MGD. It would be equipped with the following appurtenant facilities: in-line valves to control and isolate flow in the pipeline, air valves, blowoffs, pressure-reducing valves, access manways, access roads, and backup (emergency outage) facilities to provide water supply to the future AWTP for maintenance, operations, and print startup when the ATWP or South Bay Aqueduct is out-of-service.
