Las Vegas Aquifer Storage & Recovery: Feasibility Evaluation and Operations

This seminar explores the innovative water storage and recovery program in Las Vegas, Nevada. It covers the hydro-geological setting, water quality, production yield, and challenges like water level declines and planned growth. The approach of using basins vs. wells, old vs. new wells, and recovery locations is analyzed. Demonstration operations, wellhead equipping, and optimization strategies for efficient hydro-geo operations are discussed. Lessons learned from pre-development conditions, hydro-system changes, and aquifer recovery are shared, highlighting the importance of sustainable water management.
