Further request authorization for the City Controller to disburse all funds related to this item.

Report
Summary
The purpose of this agreement is to improve the reliability of the Val Vista Water Treatment Plant's power supply by allowing SRP to construct a firewall between existing substation transformers and add necessary main power disconnects. A 2016 study of the substation found: 1) a firewall barrier was needed between the two side-by-side substation transformers to prevent equipment fire; and 2) an additional breaker needed to be installed to prevent failure of the main power substation due to fire or other catastrophic events, which would result in a complete plant shutdown.
Financial Impact
Funding for this agreement in the amount of $931,019 is available in the Water Services Department Capital Improvement Program budget.
Location
Val Vista Water Treatment Plant, 3200 E. McDowell Road, Mesa, Ariz.
