CITY COUNCIL ACTION REPORT
SUBJECT:
AUTHORIZE BUDGET AMENDMENTS AND EXPENDITURES FOR CIP PROJECT #60109
STAFF PRESENTER(S):
Barbara Chappell, Water Services Director; Lisa Melton, Senior Project Manager
SUMMARY
Request City Council to approve budget amendments and authorize expenditure of funds up to $5,000,000 for construction of improvements at the Goodyear Water Reclamation Facility (WRF).
RECOMMENDATION
Approve budget amendments of $4,000,000 and authorize expenditure of funds up to $5,000,000 to increase the rated capacity of the Goodyear Water Reclamation Facility (WRF) from 6.0 to 7.5 million gallons per day (mgd), for CIP Project # 60109. (Barbara Chappell, Water Services Director; Lisa Melton, Senior Project Manager)
FISCAL IMPACT
The Goodyear WRF Expansion, CIP Project # 60109, was approved in FY2023 with a total project budget of $2,000,000 for an initial study and preparation of a Basis of Design for expansion which has been completed for $1,000,000. The proposed construction cost is $5,000,000 that will come from the remaining $1,000,000 and a budget amendment of $4,000,000. Funding for this project is currently available in the North Wastewater Development Impact Fee Fund.
BACKGROUND AND PREVIOUS ACTIONS
The Goodyear WRF Expansion evaluated options to address short-term growth in the WRF service area. The project delivered a Basis of Design Report and design to support increasing capacity to 7.5 mgd. Construction of improvements will be incorporated in multiple process areas to increase hydraulic and treatment needs. The master plan of the Goodyear WRF has been removed from the original scope to a separate project (CIP Project # 60112), approved by Council on March 6. A future project based upon the results of the master plan for the full WRF design and expansion is anticipated in FY2027.
STAFF ANALYSIS
Improvements at the Goodyear WRF will increase capacity from 6.0 to 7.5 mgd, addressing short-term growth, and removing the need for enhanced monitoring as required by the Maricopa County Environmental Services Department. Process improvements will be implemented in the aeration basins, tertiary filters, effluent pumps, potable water and digester. This project is being completed in parallel with the Brine Line Project, which will increase available capacity at the Goodyear WRF.
