Transmission System Projects
After collecting and treating water, it must be delivered to the various water purveyors throughout the Las Vegas Valley. Transmission system project improvements involved laying miles of large diameter pipe and constructing pumping stations and reservoirs. 
The projects listed below are now complete.
East Valley Lateral
The East Valley Lateral increases the water delivery system's capacity and enhances its reliability for the eastern portion of the Las Vegas Valley.
- 14 miles of pipeline
- $111 million project total
- Completed in 2005
- Sloan Pumping Station (111 million gallons per day capacity)
- Lamb Pumping Station (111 million gallons per day capacity)
- Grand Teton Reservoir (10 million gallons per day capacity)
West Valley Lateral
The West Valley Lateral was one of the first projects of the Capital Improvements Program completed.
- 6.9 miles of pipeline
- Simmons Pumping Station (71 million gallons per day capacity)
- Completed in 1997
- $40.1 million total project cost
North Valley Lateral
The North Valley Lateral consists of seven separate construction programs. They include:
- 12.3 miles of pipeline in the northern and western parts of the valley
- $91 million total project cost
- Gowan Pumping Station (24 million gallons per day capacity)
- Decatur Reservoir (20 million gallons per day capacity)
- Decatur Pumping Station (81 million gallons per day capacity)
South Valley Lateral
This project serves Henderson and other areas throughout the valley's southern region.
- Spans 27 miles across the south end of the valley
- $160.5 million approximate project total (not including expansion projects)
- River Mountains Pumping Station (315 million gallons per day capacity)
- Burkholder Reservoir (50 million gallons per day capacity)
- Horizon Ridge Reservoir (20 million gallons per day capacity)
