Summary
Public Works director presented change order No. 4 for the wastewater treatment plant Phase 2A solids-treatment improvements — primarily mechanical and site items totaling about $314,000; the project remains largely complete and is expected to integrate systems through 2026.
Public Works staff presented change order No. 4 Sept. 8 for the wastewater treatment plant Phase 2A project, describing a package of small-site and mechanical items related to the solids-treatment train. Director Maria Sarah said the Phase 2A work focuses on solids dewatering and thickening so biosolids can be transported off-site. The original contract was awarded at just under $14 million; earlier change orders totaled about $350,000. Change order No. 4 is for $314,000 and covers identified site repairs, mechanical adjustments and items that emerged during system integration and start-up. Sarah said most major construction tasks are complete and portions of the facility have been turned over to operations, but integration of components requires additional effort and sequencing; staff anticipates completion during 2026. The change-order request covers identified corrective work, additional mechanical components and areas of resurfacing uncovered during construction. No council vote on the change order is recorded in the Sept. 8 workshop minutes; staff recommended approval and offered to answer technical questions.
