Reason for Recommended Action/Background
The landfill has several class 2 (double lined) liquid surface impoundments to retain and treat both landfill leachate (water that has percolated through waste) as well as the various liquid waste (septage, portable toilet, various sump waste, etc) received at the landfill. Currently, the landfill utilizes floating surface aerators to treat this liquid, but due to the increasing volume of liquid wastes received at the landfill, an upgrade to this system is necessary. The Waste Management Unit H Aeration System will utilize a centrifugal blower and fine bubble diffusion system to more effectively aerate and treat the waste.
The current division budget for fiscal year 2021-2022 includes $300,000 for completion of this work, however, the current engineer's estimate is $320,000. The recommended actions include only approval of the plans and authorization for competitive bidding. Following receipt of bids, staff will return to the Board for approval of the agreement and, if bids exceed the budgeted amount of $300,000, a budget resolution to amend the division's fiscal year 2021-2022 budget.
