STRATEGIC PLAN ALIGNMENT

RECOMMENDATION

Authorize the expenditure of wastewater asset management funds up to $655,000 for the Lost Lift Station Odor Scrubber Replacement project. (Barbara Chappell, Water Services Director)

FISCAL IMPACT

The Lost Lift Station Odor Scrubber Replacement project is currently programmed in the FY2025 Wastewater Asset Management Plan. The Wastewater Asset Management fund has $4,502,800 in available funding.

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.

STAFF ANALYSIS

The wastewater collections department identified elevated corrosion in the manholes and on the Lost Lift Station equipment. The increase in sewer flows has produced a high level of hydrogen sulfide odor and the current equipment has surpassed its life cycle and is unable to mitigate the odor requirements. The replacement of the odor scrubber at the Lost Lift Station is necessary to eliminate premature equipment failure and will remove 99% hydrogen sulfide odors. The new 10-year warrantied media will reduce man-hours, maintenance, and operating costs while aligning with asset management and a 10-year lifecycle for the equipment. The replacement of the odor control scrubber will be completed by a job order contract (JOC) contractor with an estimated completion date of June 2026.
