Facilities

Projected water purveyor demands in the southern area of the Las Vegas Valley and the need to increase the reliability and flexibility of the SNWA water supply system have resulted in the proposed South Valley Facilities Expansion Project (SVFE) to redistribute, treat and convey existing water supplies to meet the water demand projections and use patterns in this area. 

SNWA is working in advance to secure the rights-of-way for the SVFE project, which would not begin construction for several years.

The SVFE would increase treatment and conveyance capacity to allow SNWA to redistribute existing water supplies to locations identified by the City of Henderson and the Las Vegas Water District to meet projected water demands and to increase the flexibility and reliability of the SNWA system to meet seasonal and regional water needs.  The SVFE consists of two major elements:

1. An expansion of raw water transmission and treatment facilities (the treatment element)
2. Construction of a new transmission system to convey treated water to the southern area of the Las Vegas Valley (the conveyance element)

The expansion and treatment element of the SVFE includes upgrades and additional facilities to redistribute raw water from existing sources at Lake Mead to the River Mountains Water Treatment Facility (RMWTF); expansion of treatment capacity within the existing footprint of the RMWTF; and enhancement of existing pumping station capacity and water filtration rates. 

The conveyance element of the SVFE Project would increase SNWA's management flexibility and system reliability by supplying water to locations identified by the City of Henderson and Las Vegas Valley Water District, and through a planned interconnection with the South Valley Lateral, would allow areas to be served from either lateral if needed as a result of maintenance, repair or power outage.

Facilities proposed as part of the SVFE include:

• Pipelines
• Pumping stations
• Regulating reservoirs
• Expansion of the River Mountains Water Treatment Facility
• Rate-of-flow control stations
• Tunnel portals
• Power facilities
• Appurtenances

The proposed facilities are generally displayed on the Project Map. The proposed facilities will be located predominantly on public lands managed by the Bureau of Reclamation, Bureau of Land Management, and the National Park Service – Lake Mead National Recreation Area. Potential project alternatives include different pipeline alignments, different pipeline construction methods (trench excavation and tunneling), and different locations for pumping stations, storage reservoirs and appurtenant facilities.
