Description
Request to authorize the City Manager, or his designee, to execute an amendment to Agreement 149215, with Salt River Landfill, to provide additional funding to the agreement.

Report
Summary
The purpose of the amendment is to request additional payment authority of $1,000,000 for supply of landfill services required by the Water Services Department (WSD). WSD uses Salt River Landfill services related to disposal of plant sludge, clean dirt and green waste such as grass, tree branches and weeds. The Salt River and Verde River watersheds are the main sources of surface water that is supplied to the drinking water plants. The process of removing settled sludge from the water treatment process includes disposal in local landfills.
The services provided by Salt River Landfill have experienced three price increases in the past three years, contributing to a higher cost of purchase from the original contracted amount. Additionally, the City has increased the amount of water treatment plant sludge and green waste disposal from approximately 30,000 to 40,000 tons per year. Combined, these changes have contributed to a need for additional funding to support the required service.
Agreement Term
The agreement term will remain unchanged ending on Feb. 19, 2024.
Financial Impact
- The initial authorization for Landfill Services was for an expenditure not-to-exceed $4,688,000.
- This amendment will increase the authorization for agreement by an additional $1,000,000, for a new total not-to-exceed agreement value of $5,688,000.
Funding is available in the Water Services Department's Operating budget.
