Will the sediment basin be lined and, if not, will the basins be in groundwater from 4 or 5 feet below existing ground level and below? Does DCA expect the slurry walls to keep them out of the groundwater?
June 15, 2020Is the corridor that was proposed through the Deep Water Ship Channel with an intake near Rio Vista still a possibility?
June 15, 2020The NOP described the project with a capacity of 6,000 cubic feet per second (cfs) with a possible range in capacities of 3,000 to 7,500 cfs. At this time, DCA is considering tunnel sizing design criteria for gravity flow from the intakes to the pumping plant near the Southern Forebay. DCA is not considering design criteria for pressurized flow in the tunnel.
