Granite-Led JV Tapped for Two Major Southern Nevada Water Projects

The Southern Nevada Water Authority (SNWA) chosen a three way partnership of Granite Development and Contri Development to construct two pumping stations and pipelines projected at between $450 to $520 million—elements of a multibillion-dollar effort aimed toward bolstering water safety and increasing service within the Las Vegas Valley.

The Southern Nevada Development Companions (SNCP) three way partnership has already began preconstruction work on the Rice Pumping Station and Interconnect Pipeline and the Paradise Hills Pumping Station and Pipeline Mission. Development on each is predicted to start in 2027 and completed in 2030. The 2 contracts issued to the three way partnership cowl preconstruction work, with last development contracts to be negotiated nearer to the beginning of development.

The Rice mission features a new 30 million-gallons-per-day (mgd) pumping station on the current Thomas Rice Reservoir and Pumping Station website within the western valley. Moreover, a 21,000-linear-ft, 42-in.-dia metal water pipeline might be put in to convey water southwest to the Spring Mountain/Durango Reservoir.

The three way partnership was awarded a $15 million preconstruction companies settlement in Might, and its affiliation with the mission was introduced on June 25. The mission is predicted to transition right into a development section of $100-$120 million, with Granite’s portion being roughly $70 million.

Earlier this week, SNCP introduced it had been chosen to construct the $350-$400 million Paradise Hills Pumping Station and Pipeline Mission in Henderson, southeast of Las Vegas.

The work is a part of the company’s multi-billion greenback Horizon Lateral Program aimed toward upgrading water supply companies throughout Southern Nevada. Water deliveries to the realm are at present offered by large-diameter transmission pipeline often called the South Valley Lateral (SVL) constructed three many years in the past. 

To satisfy the calls for introduced by the speedy improvement of the area and anticipated future demand, SNWA developed the Horizon Lateral Program; a two-phase bundle of associated giant transmission and storage initiatives.

The work awarded to SNCP
consists of set up of roughly 22,000 linear ft of 120-in.-dia metal water pipeline, that includes as much as three trenchless crossings beneath vital infrastructure: an current 108-in. waterline, Interstate 11; and Union Pacific Railroad tracks. The pipeline can even embody a number of valved shops for future connections to Boulder Metropolis, a metropolis of Henderson reservoir, and all elements of SNWA’s Horizon Lateral Program.

Because the JV lead, Granite will carry out clearing and grubbing operations, construction excavations and backfill, forming and putting of concrete constructions, set up of entry roads alongside the pipeline alignment, demolition and restoration of current roadways, and set up of all pump station constructions and gear. Granite’s complete estimated development contract worth is $240 million. Contri might be liable for putting in the 120-in. pipeline and related fittings.

The Paradise Hills Pumping Station might be constructed on metropolis of Henderson land and can open with a 35 mgd capability, with eventual enlargement to 65 mgd.
