RECOMMENDATION
Approve expenditure of funds up to $2,400,000 for the replacement of sewer lines located in the Corgett Wash (Project 61002). (Barbara Chappell, Water Services Director)
FISCAL IMPACT
The Corgett Wash Sewer Line Replacement (Project 61002) has an approved project budget of $2,455,000 in the FY2024 Capital Improvement Program funded through wastewater operating funds; $55,000 of the funds have been set aside for preconstruction services performed by our contractor.
BACKGROUND AND PREVIOUS ACTIONS
Per City of Goodyear Resolution 08-1255, all expenditures of budgeted funds in excess of $500,000 must obtain Council approval. The city has developed and approved a Capital Improvement Program for FY2024 through FY2028. The subject sewer lines are planned to be replaced in FY2024 per this plan. Due to the complexity of the replacement of sewer lines in the Corgett Wash, a JOC has been selected and provided a scope of work and project costs.
STAFF ANALYSIS
The purpose of this project is to improve sections of ductile iron pipe (DIP) in the Corgett Wash at seven locations. The existing pipe is severely corroded to the point where it needs to be improved. The scope includes an analysis of CIPP (Cured In Place Pipe) liners at each location. If CIPP is feasible, it will be utilized; if not, the pipe will be removed and replaced.
The sewer lines were installed in 1986, and it is the main trunk line that transfers wastewater to the Corgett WRF. This replacement project will increase the reliability of wastewater service for the residents in the area. If not addressed, the pipe will eventually fail and cause a major sewer overflow in the Corgett Wash. This will result in an emergency repair, a possible service disruption to residents and businesses, additional regulatory oversight, and increased costs in the replacement of these sewer line segments.
There are seven total crossings that are planned for improvement. The total project funding is split over two fiscal years, FY24 and FY25 ($2,455,000 in each year). This expenditure request is for the first fiscal year.
