Resolution No.
STOCKTON CITY COUNCIL
RESOLUTION AUTHORIZING A CONTRACT WITH USALCO, LLC FOR A TOTAL NOT TO EXCEED AMOUNT OF $2,423,600 FOR THE PURCHASE OF WASTEWATER TREATMENT POLYMER The Municipal Utilities Department operates and maintains the Regional Wastewater Control Facility (RWCF), an advanced tertiary sewer treatment facility with a 55 million-gallon per day capacity, located adjacent to the San Joaquin River; and The RWCF includes Dissolved Air Flotation Thickeners within its tertiary treatment system. These units add polymer for the removal of suspended solids from wastewater. Polymers are coagulants that thicken the solids in wastewater, making it easier to separate them; and The type, dosage, and application rate of polymer used in wastewater treatment depends on the specific characteristics of the wastewater. A product that performs well at one treatment plant may not be suitable for another, given the variability in wastewater composition and the need to meet distinct treatment requirements; and On December 29, 2025, staff published PUR 26-019 in the Stockton Record inviting bids for the purchase of wastewater treatment polymer. Additionally, the bid specifications were sent to prospective bidders via Ask Stockton; and Bench-scale testing was conducted during the week of January 20, 2026. During the week of February 2, 2026, two participating vendors conducted full-scale performance testing; and On February 26, 2026, the City Clerk received two sealed bids. USALCO, LLC of Baltimore, Maryland, submitted a bid that was regular in all aspects with a cost of $0.548 per pound. Staff estimate an annual maximum purchase of approximately 764,000 pounds of Delta-Floc 1176 polymer; now, therefore, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF STOCKTON, AS FOLLOWS:
The Specifications and Addenda for the Invitation for Bids for the Purchase of Wastewater Treatment Polymer (PUR 26-019) are hereby accepted and attached as Exhibit 1 and incorporated by this reference.
The City Manager is authorized to execute a five-year contract with USALCO, LLC of Baltimore, Maryland, to provide polymer at the Regional Wastewater Control Facility for a total not-to-exceed amount of $2,423,600, a copy of which is attached as Exhibit 2 and incorporated by this reference.
The City Manager or designee is hereby authorized to take necessary and appropriate actions to carry out the purpose and intent of this Resolution.
