The Delta Conveyance Project does have a larger southern forebay based on the known engineering details at this time. She also noted that the Delta Conveyance Project does not have an intermediate forebay as the hydraulic analysis found it was not necessary the Water Fix had an intermediate forebay on Glenville Tract. She pointed out that one of the implications of the change in the size of the tunnel is that there will be less reusable tunnel material produced by construction of the tunnel. California Water Fix had two tunnels with a 40 foot inside diameter the Delta Conveyance Project is looking at one tunnel with a 36-foot inside diameter. There’s also a decrease in the size and the number of tunnels. California Water Fix had three intakes at 9,000 cfs capacity and Delta Conveyance Project has two intakes for a total of 6,000 cfs capacity. Buckman noted that the central alignment of the Delta Conveyance Project is a similar alignment to the California Water Fix proposed project, but there is a decrease in the number of intakes and overall capacity. The map shows two potential tunnel alignments: an eastern alignment and a central alignment (of which they will pick one).ĭifferences between the Delta Conveyance Project and the California Water Fix There is a southern forebay adjacent to Clifton Court Forebay and a pumping plant that pumps water from the tunnel up into the southern forebay, and then a conveyance facility to connect that southern forebay to the existing south Delta pumping plants. There are then tunnel reaches and tunnel shafts to connect those intakes to the South Delta. The project facilities include two intake facilities on the Sacramento River the Notice of Preparation identified three potential locations, but they will only pick two. The map on the slide is an updated version that has some more specifics. ![]()
