SOUTHWEST AQUEDUCT – REACH 1

Project Description

The project generally included construction of approximately 12,000-feet of new 66-inch to 90-inch diameter welded steel pipeline, large valve vaults, large diameter isolation and flow control valves, a new standpipe facility, and numerous large diameter fittings, special fabrications, appurtenances, and connections. The mainline Southwest Aqueduct – Reach 1 consisted of 66-inch diameter welded steel pipeline beginning at the Jordan Narrows Pipeline connection to Jordan Aqueduct – Reach 1 and running parallel to JA-1 to the Jordan Valley Water Treatment Plant in Bluffdale, Utah. The project included significant connections and improvements at four separate sites within Salt Lake and Utah counties, including the Point of the Mountain, Jordan Narrows Pump Station, Jordan Narrows Pipeline Interconnection, and Jordan Valley Water Treatment Plant. Some significant elements of the project included: connection to Jordan Aqueduct – Reach 4 downstream of the Flow Control Facility at Point of the Mountain; a new standpipe and valve vault at Point of the Mountain; connections to the Point of the Mountain siphon and penstock; modification within the Jordan Narrows Pump Station, including the addition of 2 new 36-inch flow control plunger valves, isolation of the pump station discharge header, and installation of a new 54-inch flow meter; construction of a new Interconnection Valve Vault between the Jordan Narrows Pipeline, Southwest Aqueduct – Reach 1 and Jordan Aqueduct – Reach 1; installation of a new fiber optic line along the Southwest Aqueduct – Reach 1 alignment; construction of approximately 12,000 feet of new 66-inch to 90-inch diameter welded steel pipeline and associated special fittings and appurtenances; construction of a Connection Vault at the Jordan Valley Water Treatment Plant to tie Southwest Aqueduct – Reach 1 into the Upper Raw Water Reservoir and Jordan Aqueduct – Reach 1 Bypass Pipeline. Construction of a new 90-inch bypass pipe at the downstream end of the Upper Raw Water Reservoir at Jordan Valley Water Treatment Plant; and the associated civil, mechanical, structural, electrical and instrumentation work required for the project.
