Report
Summary
Scottsdale provides water and sewer services for County lands located east of 56th Street and south of Lone Mountain Road. A new single-family residential subdivision is planned along 56th Street, approximately a half mile south of Lone Mountain Road near the Montgomery Road alignment. Scottsdale has waterlines in the immediate area to provide water service but does not have sewer infrastructure nearby.
This IGA will allow Phoenix to provide wholesale sewer service to Scottsdale until it can bring sewer infrastructure to this area. Scottsdale will be responsible for constructing, maintaining, and ownership of the infrastructure upstream of the connection to Phoenix’s system at 56th Street and Milton Drive, just south of Montgomery Road. Scottsdale will be responsible for all customer connections and billing. Phoenix will be responsible for transportation and treatment of the sewer flow from the point of connection to the nearest wastewater treatment plant. Phoenix will invoice Scottsdale for the sewer transportation and treatment service each month based on the volume of sewer flow received from Scottsdale. Phoenix will charge Scottsdale a wholesale rate based on the actual capital, operating and maintenance costs of transporting and treating the wastewater, as determined by a cost-of-service study.
Contract Term
This IGA term is five years from the effective date and upon mutual agreement the parties may extend this agreement for one, additional five-year term.
Financial Impact
Scottsdale will pay Phoenix for the transportation and treatment as determined by a cost-of-service study.
