"SNWA Well System Management Program and Well Performance and Repair Cost Case Study"

By:  Jason Mace,

Hydrologist II, Las Vegas Valley Water District / Southern Nevada Water Authority

Abstract:

The LVVWD and SNWA operates over 100  production, recharge, and irrigation wells in the Las Vegas Valley, surrounding small communities and program areas. A well management program was developed in order to optimize well performance and maintain long term system production capacity. Well and pump attribute data, historical operation and hydrologic databases track well performance and condition. The longevity of each well is estimated based upon construction date, casing materials and condition to establish well replacement priorities. Pump performance is monitored including amperage and flow rates and changes in sand content, turbidity and well specific capacity are tracked to identify screen damage or plugging in order to identify wells requiring rehabilitation or repair.  After pump removal, wells are inspected using downhole videos and a Casing Inspection Thickness Measurement survey to identify casing competency and provide a baseline for future comparisons. The presentation presents the well management program elements and well performance and a deep dive in to a specific well repair case study.
