Title
Authorization to Enter into Groundwater Savings Facility Agreement with Roosevelt Irrigation District (Ordinance S-47857)
Description
Request to authorize the City Manager, or his designee, to enter into a Groundwater Savings Facility Agreement with the Roosevelt Irrigation District to store effluent, Central Arizona Project water, and New Conservation Space water. Since 2000, the City and Roosevelt Irrigation District have been parties to a Groundwater Savings Facility agreement to store City effluent at the Roosevelt Irrigation District-permitted Groundwater Savings Facility. This new agreement expands, amends and restates the original agreement to include Central Arizona Project and New Conservation Space water. Further request to authorize the City Treasurer to accept all funds related to this item.
Report
Summary
The Water Services Department produces more reclaimed water at the 23rd Avenue Wastewater Treatment Plant than can be exchanged under the current arrangements, and that reclaimed water can be stored for future use through the Roosevelt Irrigation District (RID) Groundwater Savings Facility (GSF). Further, under the Agreement, the City will have the opportunity to use the RID Groundwater Savings Facility to store Central Arizona Project (CAP) water and New Conservation Space (NCS) water from Modified Roosevelt Dam for future use, providing increased flexibility for the City’s use of those waters in the future.
Contract Term
The contract automatically renews on a year-to-year basis, but either party may terminate the Agreement at the end of any year by providing timely notice to the other party.
Financial Impact
For each acre-foot of water delivered by the City to the RID Groundwater Savings Facility, RID will pay the City $15, adjusted each year by the CPI-U (All Urban Consumers, U.S. City Average).
