Title
Intergovernmental Agreement for Delivery, Treatment, and Wheeling of Avondale Colorado Water to Avondale through City of Phoenix Infrastructure to an Avondale Interconnect (Ordinance S-44009)
Description
Request to authorize the City Manager, or his designee, to execute an Intergovernmental Agreement (IGA) between the City of Phoenix and the City of Avondale for treatment and delivery of Avondale's Colorado River Water through Phoenix's existing water infrastructure and distribution system to an interconnection with Avondale's water distribution system.
Report
Summary
Avondale currently has a subcontract for 5,416 acre-feet of Colorado River water annually, but is unable to take direct delivery of its Colorado River Water due to lack of delivery infrastructure between the Central Arizona Project aqueduct and Avondale's water service area. This lack of physical availability to its Colorado River water impacts Avondale's resilience and forces it to rely upon groundwater sources. By using available capacity in Phoenix's water treatment and distribution system, Avondale can construct an interconnect with Phoenix and take direct delivery of its Colorado River supplies at times and in volumes of its choosing. Avondale will pay Phoenix all transportation and treatment costs. Avondale will be solely responsible for constructing infrastructure to connect with Phoenix's existing infrastructure.
This agreement provides both emergency backup to Avondale's water system, as well as resilience for long-range planning.
Contract Term
This IGA contract term is for 10 years, with an option to extend the term up to 10 years, which may be exercised by the City Manager or his/her designee.
Financial Impact
There is no net financial impact to Phoenix. Avondale will purchase its own Colorado River allocation and pay Phoenix the actual treatment and delivery costs. Avondale will also pay all costs associated with construction and operation of an interconnection with Phoenix's existing water distribution system.
Location
The treated water will be delivered through an interconnection facility near 107th Avenue and Indian School Road.
