The project scope will replace the existing knife gate valves and flanged coupling adapters on the three 42-inch diameter influent wastewater pipelines that transport wastewater from the District's major pumping stations to the Alvarado Wastewater Treatment Plant's Headworks process.  The knife gate valves are critical in the isolation of wastewater into the treatment plant for operations and maintenance requirements.
