City staff presented several wastewater‑system procurements and sole‑source recommendations at the Oct. 22, 2025 agenda‑study session, saying the items are budgeted in the FY26 wastewater budget and requested placement on the consent agenda for formal approval.

Cedar Trails Landfill: Staff described a sole‑source approval to contract for biosolids disposal at Cedar Trails Landfill, which the city said is the only local facility accepting the materials. The estimated disposal cost is $500,000 for the coming period. Jeremy Jacobson, Wastewater Treatment Manager, said the city produces roughly 58 wet tons a day and about 300 wet tons a month; biosolids are typically disposed at about 20% dryness.

Evacqua Adolphos: Staff requested authorization to buy approximately 115,000 gallons of an iron‑salt solution (Adolphos) used at the Glendale wastewater treatment facility for odor and corrosion control, at an estimated total of $195,500 (product plus delivery); purchases will be piggybacked off a contract used by Punta Gorda and treated as sole‑source for this vendor.

KED Group polymers: Staff requested a sole‑source purchase order for approximately 360,000 pounds (multiple blends) of polymer used for thickening and dewatering at Glendale and Northside wastewater plants, at an estimated cost of $807,980; KED Group is described as the only provider of the specific polymer blends used by the plants.

Walker Process clarifier replacement: Water Utilities presented a sole‑source purchase and installation of a spiral flight circular collector for an 85‑foot diameter primary clarifier at Glendale, replacing equipment that staff said has reached the end of its service life; the parts and installation cost was estimated at $830,250 plus an $83,000 contingency (total $913,250); Walker Process Equipment was identified as original manufacturer and sole‑source for direct replacement equipment.

Staff said funds for each procurement are included in the FY26 wastewater budget and that operational constraints (unique blends, proprietary equipment, local disposal availability) justify sole‑source treatments. The items were described as routine but significant recurring costs and were recommended for consent‑agenda approval.

Why it matters: These procurements maintain wastewater treatment operations, manage disposal of biosolids the city cannot land‑apply, and replace aging treatment equipment; several were identified as sole‑source because of proprietary blends, original equipment manufacturer status or limited local disposal capacity.

Next steps: Staff will place the purchase orders and sole‑source approvals on the consent agenda for formal commission action; work and deliveries will proceed under standard contracting and maintenance schedules.
