The LPP is necessary because the project:
Diversifies water supply and enhances its reliability
Most southern Utah residents currently depend on a single water source of variable quality and quantity – the Virgin River basin. The LPP diversifies the region’s water sources, which is a key objective of prudent water managers throughout the western United States.
Meets future water demands
Washington County is one of the nation’s fastest growing regions. Current state population projections estimate the county will increase by 155% by 2060. In addition to residents, Washington County attracts more than 6 million annual visitors and thousands of seasonal residents who own more than 20% of the county’s homes. The high visitor volume and seasonal population add significantly to Washington County’s water demand.
Adds resiliency and reliability to the water delivery system
LPP provides needed system redundancy, which adds a barrier against single system failure and climate variability.
Addresses long-term uncertainty
Water is not a real-time commodity that can be “manufactured” or delivered on a real time basis. Water shortages are not an option.
Protects the environment
The LPP will ensure that up to 83,756 acre feet of water will continue to flow more than 400 miles downstream through valuable riparian and fish habitat in the Colorado River system.
Helps ensure regulatory compliance
Water providers like WCWCD must plan and design facilities that are reliably capable of supplying adequate quantities of water that consistently meet applicable drinking water quality requirements and do not pose a threat to general public health.
