Sedona City Council voted unanimously 7-0, with Councilman Pete Furman attending remotely, to award a nearly $749,000 construction contract to Fann Environmental LLC for the rehabilitation of the wastewater reclamation plant’s secondary clarifier during its March 24 meeting.
While the wastewater plant has three secondary clarifiers that use gravity to remove solids from the wastewater, Director of Wastewater Roxanne Holland said. Unit No. 2 has been inoperable since a 2024 equipment failure.
The plant can handle peak flows but lacks redundancy to ensure the plant can reliably meet its permit requirements if another clarifier fails while unit one is in need of repairs.
“The rehabilitation consists of replacing original equipment with a new clarifier mechanism, drive system, skimmer arm, counter balancing arm, suction header, and scum pump on each clarifier,” the council agenda reads.
“The two that we have are operating really well and for our normal flows during the day, we have plenty of capacity with one,” Holland said. “It’s those peak flows, like when the most flow is coming out to the plant, or if there’s a rain event that we have some inflow that comes out to the plant, that’s when it would become an issue. And we can always divert some of the flow to storage basins and then reintroduce them when flows drop back off. So there’s ways around not having redundancy. It’s not pretty or easy, but we can adapt.”
Fann’s bid was $748,774, followed by ASR Construction Group $1,258,687, and KEAR Civil Corporation $1,292,800.
The new equipment is expected to be installed in March 2027 and be completed in July 2027.
