RFP 26-139 - Wastewater Treatment Plant & Recycled Water Upgrades

The City of Banning has issued Request for Proposal RFP 26-139 to solicit qualified engineering consulting firms for the modernization and expansion of its Wastewater Treatment Plant (WWTP) and recycled water facilities. The project aims to increase the plant's capacity from 3.6 million gallons per day to 4.8 million gallons per day, ensure compliance with impending regional water quality standards, and enable the production of Title 22 tertiary recycled water. The scope of work includes project management, technical evaluation of alternatives such as zero liquid discharge, professional design, permitting support, and bidding assistance, with optional construction-phase engineering services. The successful consultant will be responsible for delivering a complete Plans, Specifications, and Estimates (PS&E) package through a phased milestone process and must coordinate with various regulatory agencies including the RWQCB, DDW, and SAWPA. This solicitation is supported by a federal grant from the Bureau of Reclamation under the Title XVI Water Recycling and Desalination Construction Program, which carries a total approved budget of $64,778,302. Consequently, the selected contractor must comply with federal requirements such as Build America, Buy America (BABAA) and specific grant reporting mandates, in addition to California prevailing wage laws and Cal-OSHA regulations. Interested firms must register on the City's Electronic Bidding System and submit a proposal that includes a detailed project schedule and a fully itemized, not-to-exceed fee proposal. The deadline for proposal submission is September 25, 2026, at 4:00 pm, following a mandatory pre-proposal meeting held on August 17, 2026.
