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, delivering one of the state’s most reliable water supplies, the Colorado River, to southern Utah.

Meets future water demands

LPP is necessary to meet current and projected water demands in Washington and Kane counties while maximizing the use of existing available water supplies. Population growth projections show that water demand will exceed local supplies, resulting in shortages if additional water sources aren’t secured.

Projected Population Growth by Decade

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. LPP is needed as early as 2028.

Protects the environment

The LPP will ensure that more than 86,000 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.
