The project consists of the partial replacement of the Cunningham Siphon. This existing, raw water conveyance currently runs underground, crossing under both Dog Bar Road and Alta Sierra Drive to meet the Rattlesnake Canal. NID proposes to replace the existing 22-inch, thin-walled steel siphon pipe with a new minimum size of 24-inch diameter pipe. The new pipeline would be re-routed, beginning after the existing siphon crosses under Dog Bar Road, to an alignment that parallels that road. The replacement pipe would be installed in the dirt shoulder of the road. No change would be made to the Dog Bar Road pipeline crossing.
