Reconditioning of Sewer Drying Beds at WRF1

The City of Corona Utilities Department is seeking qualified contractors to redevelop its 1966‑era sludge drying beds at Water Reclamation Facility #1 (WRF‑1) into a modern, multi‑bay Sewer Vactor Trunk Dump Station. The project will replace aging drying beds, install new equipment to separate solids from liquid waste, and return the liquid portion to the headworks. Bidders must be pre‑qualified contractors on the City’s list, submit all required forms electronically via PlanetBids, and acknowledge any addenda. The work is expected to start around April 2026 and includes a 15‑day move‑in period followed by 45 working days of construction. • Convert existing drying beds to a multi‑bay Sewer Vactor Trunk Dump Station. • Provide all civil, mechanical, and electrical work necessary for the new system. • Comply with City of Corona pre‑qualification, licensing (“Class A General Engineering Contractor License”), and renewable‑diesel fleet compliance requirements.
