AI overview

The City of Banning (City) is soliciting proposals from qualified engineering consulting firms to provide professional engineering design, permitting support, bidding assistance, and optional engineering services during construction for the phased modernization and expansion of the City's Wastewater Treatment Plant (WWTP) and recycled water facilities. The selected Consultant shall provide a multidisciplinary team capable of delivering a complete set of Plans, Specifications, and Estimates (PS&E) suitable for public bidding while supporting the City's funding, regulatory, and operational objectives.

The City owns and operates a WWTP located at 2242 East Charles Street, Banning, California 92220. The WWTP has a design treatment capacity of 3.6 million gallons per day (MGD) and currently discharges approximately 2.1 MGD into 10 unlined evaporation/percolation ponds. The City's end goal is to select and construct a treatment alternative for the removal of nitrogen and the production of Title 22 recycled water that is the best fit for the City's current and future goals. The existing WWTP requires significant upgrades to meet the regional water quality control board's impending effluent water quality standards, increase capacity to approximately 4.8 MGD, produce Title 22 tertiary recycled water, and position the facility for future reverse osmosis (RO) and brine management improvements.

Key dates include a pre-proposal conference on August 17, 2026 at 5:00 PM, a Q&A deadline on September 4, 2026 at 7:00 PM, and a proposal submission deadline of September 18, 2026 at 11:00 PM. The City has previously completed planning studies, basis of design, preliminary engineering, surveying, geotechnical investigations, and other technical work that will be made available to the successful Consultant. Proposals must be submitted through the City's procurement portal. The contract will be awarded based on evaluation criteria including qualifications, approach, experience, and pricing.
