ITB for Aluminum Based Coagulant

The City of Portland, Oregon is reposting an Invitation to Bid for aluminum-based coagulants for wastewater treatment at the Columbia Boulevard Wastewater Treatment Plant following cancellation on April 23, 2025 due to insufficient competition — only one responsive bid was received in the initial solicitation (ITB 00002524), which prevented the City from achieving its intended multi-award structure. The reposted ITB will have a new bid due date to be announced; the original deadline was April 11, 2025.

The scope covers high-basicity polyaluminum chloride or high-basicity aluminum chlorohydrate coagulants for chemically enhanced primary treatment (CEPT) of wastewater. The estimated annual requirement is 35,000 gallons, totaling 175,000 gallons over a five-year contract term with pricing firm throughout. Chemical specifications include aluminum fraction of 12.1–12.8% w/w, aluminum oxide fraction of 23.0–24.2% w/w, basicity of 75–86%, and specific gravity of 1.32–1.36 at 20 degrees Celsius. All bid prices must be F.O.B. destination freight prepaid and inclusive of shipping and delivery costs. Contractors must deliver products within three calendar days of regular orders and within eight hours for emergency orders, between 8:00 a.m. and 2:00 p.m., with delivery truck capacity of at least 3,600 gallons. Safety Data Sheets must accompany all bids.

The City plans to make multiple awards to ensure redundancy and uninterrupted supply. Commercial general liability insurance of $2 million per occurrence and automobile liability insurance of $2 million are required. Payment terms are Net 30 days via electronic funds transfer. Bidders must be certified as Equal Employment Opportunity employers and comply with the City's Equal Benefits Ordinance. No performance or payment bonds are required.
