AI Summary
Yosemite National Park's Utilities Branch seeks proposals for a five-year Indefinite Delivery/Indefinite Quantity (IDIQ) contract for various polymers and liquid aluminum sulfate to enhance water and wastewater treatment at its El Portal and Wawona facilities. The El Portal Wastewater Treatment Plant (EPWWTP) requires three types of polymer: liquid Polyaluminum Chloride (PAC) for tertiary treatment (reducing turbidity and phosphorus), dry anionic polymer for secondary clarification (reducing turbidity), and a liquid polymer for centrifuging anaerobic digester solids (producing clear centrate and 24%+ total solids). EPWWTP also needs bulk liquid aluminum sulfate for secondary treatment (lowering phosphorus and turbidity). The Wawona Wastewater Plant requires liquid PAC for tertiary treatment, while the Wawona Potable Water Plant needs liquid PAC for potable water treatment, both aimed at reducing turbidity and phosphorus. All products must be NSF 60/61 approved and not cause NPDES violations. Vendors must submit samples for jar testing, provide chemical makeup results, and cost per 1,000 gallons treated. Successful vendors may undergo a full-scale treatability run. The contract will be awarded to one vendor for both locations by July 1, 2026, with deliveries made within 10 days of notice. Deliveries to El Portal are subject to a 45-foot vehicle length restriction on Highway 140, and winter deliveries to both locations may require snow chains.
