Report
Summary
The purpose of this project is for the City of Phoenix to supply water in north Phoenix in the event there are restrictions placed on Colorado River water delivered through the Central Arizona Project. The City of Phoenix treats Colorado River water at the Union Hills and Lake Pleasant Water Treatment Plants (WTP), which supply water to north Phoenix. Construction of a new 66-inch pipeline from the 24th Street WTP to 32nd Street and Bell Road is intended to allow the delivery of Salt and Verde River water into north Phoenix.
This amendment is necessary as more contract time is needed to purchase standby generators to provide power redundancy to the 24th Street WTP facilities to supply water from the 24th Street WTP to north Phoenix. This amendment will provide additional time to fulfill the agreement.
Contract Term
The term of the agreement amendment is two years from the issuance of the Notice to Proceed. Work scope identified and incorporated into the agreement prior to the end of the term may be agreed to by the parties, and work may extend past the termination of the agreement. No additional changes may be executed after the end of the term.
Financial Impact
The initial agreement value remains unchanged.
