Report
Summary
The purpose of this study is to assess potential system-wide operating scenarios, anticipate any water quality or hydraulic issues, and advise and develop recommendations for operations and improvements in the event that restrictions are placed on Colorado River water delivered through the Central Arizona Project (CAP).
Carollo's services include, but are not limited to: evaluate and provide input on future operating scenarios including use of wells and new infrastructure to deliver Salt River Project (SRP) water to north pressure zones; develop blend scenarios and perform hydraulic modeling analysis to simulate distribution system conditions, including when wells are at high production rates and when SRP water is being delivered to north pressure zones; perform field investigations, sampling, and testing as needed to assist in meeting project goals; confirm water quality model results with bench testing; provide recommendations to provide stable water quality meeting regulatory requirements and treatment chemicals/processes that will be integrated with existing City facilities, if needed; assist the City with developing an implementation plan to bring on-line the future new Zone 3D and 4A resiliency infrastructure and an operations plan for various future scenarios; and provide a distribution modeling system plan for long-term monitoring of distribution system piping changes.
