One of the most important reasons southern Utah needs the LPP is to diversify its water supply, and that is something conservation cannot accomplish. Most of southern Utah is dependent on a single water source of variable quality and quantity — the Virgin River basin.
The LPP introduces a second, more reliable, water source to the area and more than doubles Washington County’s current supply. Meeting southern Utah’s future water needs requires a comprehensive plan including more conservation and reuse, development of local supplies, free market agricultural transfers and bringing a new source of water through the LPP. The chart below outlines the role conservation and the LPP will play in meeting future demand.
