This brown bag Webinar is brought to you by the NGWA Economics of Groundwater Interest Group.

Overview

Attend this half-hour brown bag Webinar to learn how the city of Phoenix has developed a plan to manage aquifers to ensure the future availability of groundwater, sustain production capacity of its existing wells, improve groundwater quality, and reduce land subsidence.

A 40-year life-cycle cost analysis was conducted for an aquifer storage and recovery well to assess whether this system is economically feasible compared to a standard water supply well. The most cost-effective scenario identified in the analysis is an ASR well system that stores and recovers treated surface water supplies directly into the aquifer with no wellhead treatment required. The financial and operational advantages of this system include:

• Appropriately sized and existing distribution and treatment systems are critical for reducing the overall costs of an ASR well system and improving groundwater quality
• Increased utilization and improved operational programming of an ASR well makes these systems economically feasible over the long-term since there is reduced downtime due to well clogging.
