Document Description
The project involves the installation of approx 16,500 lf of water transmission main and the abandonment of the existing main within the Sweetwater River valley. The majority of the transmission main would be installed within proximity to the existing alignment, while some portions would be realigned. The majority of the new main would remain 36 inches in diameter, with the exception of a 3,100-ft reach that would be upsized to 48 inches. Installation of the new main would occur first, followed by the abandonment of the existing main by filling with concrete slurry or similar material. Construction would be accomplished primarily through open trenching, while jack and bore method would be utilized for a storm drain crossing along a limited portion of segment 1. Construction staging areas would be used for temporary storage of material.
