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—components of a multibillion-dollar effort geared 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 anticipated 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 challenge features a new 30 million-gallons-per-day (mgd) pumping station on the present Thomas Rice Reservoir and Pumping Station web site within the western valley. Moreover, a 21,000-linear-ft, 42-in.-dia metal water pipeline will likely 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 challenge was introduced on June 25. The challenge is anticipated to transition right into a development part 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 geared toward upgrading water supply companies throughout Southern Nevada. Water deliveries to the realm are at the moment supplied by large-diameter transmission pipeline often known as the South Valley Lateral (SVL) constructed three many years in the past. 

To satisfy the calls for introduced by the fast growth 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
contains 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 present 108-in. waterline, Interstate 11; and Union Pacific Railroad tracks. The pipeline will even embrace a number of valved retailers for future connections to Boulder Metropolis, a metropolis of Henderson reservoir, and all components 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 present roadways, and set up of all pump station constructions and gear. Granite’s whole estimated development contract worth is $240 million. Contri will likely be chargeable for putting in the 120-in. pipeline and related fittings.

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