Spanish Valley Water Reclamation Facility (SVWRF) in Utah is requesting quotations for two headworks screenings and grit dumpsters, with quotations due August 10, 2026 at 11:00 a.m. The specification references American Bulk Conveying Model 20 Auger-Dumpster as the baseline or approved equal, with Rocky Mountain Welding listed as an acceptable alternative container manufacturer.

Each unit must be a self-contained, integral dumpster with internal shaftless screw conveyor rated for 20 cubic-yard capacity, road-worthy and leak-proof, designed to receive, convey, and distribute municipal wastewater screenings and grit. Construction must be ASTM A36 carbon steel with exterior ferrous surfaces coated with high-build epoxy resin (minimum 16-mil dry film thickness) and interior surfaces protected with phenolic epoxy coating. The shaftless screw conveyor must be cold-formed high-strength alloy steel sized for 100-percent trough loading at maximum motor horsepower with screenings density of 70 pounds per cubic foot. All equipment and wiring must comply with Class I, Division 1, Group D hazardous location requirements and Ontario Electrical Safety Code Section 18-100 (22nd Edition 1998), with CSA certification. Power specifications require 600 VAC, NEMA 7 connectors with three 20-ampere pins for motor power and six 15-ampere pins for 120-volt controls. Equipment must interface with Republic Services hauler equipment and SVWRF's existing electrical control systems.

The supplier must deliver and commission equipment at SVWRF, provide factory certification of functionality prior to shipment, conduct on-site inspection and adjustment, and deliver a minimum three-hour training session to facility personnel. Equipment warranty covers one year from startup acceptance or 18 months from delivery, whichever is longer. Each dumpster includes spare parts: one replacement liner, one complete replacement screw, and one motor. Quotations must include anticipated schedules for submittals and manufacturing timeframes and note any deviations from specifications as exceptions. Submissions must be emailed to tworthen@svwater.com and must not be submitted through the U3P (BONFIRE) system.
