Each proposal shall be in accordance with the general provisions for purchase of work and services on file in the office of the Utilities , 777 B Street , Hayward , CA 94541-5114 . All proposals must be submitted to the City's eProcurement Portal by 5:00 pm on Friday, June 20, 2025 and clearly identified with RFP title, number, company name and due date.

The City is seeking a qualified Consultant to develop a 2025-26 flow monitoring program, collect dry and wet weather flow data, update and recalibrate the City’s Infoworks ICM hydraulic model, identify capacity needs and associated projects and priorities, and update the City’s Sewer Collection System Master Plan.

Background

The City of Hayward, California (The City), located in Alameda County, is known as the “Heart of the Bay” because of its central and convenient location to San Francisco, Oakland and San Jose. The City owns and operates its own sanitary sewer collection system and Water Resources Recovery Facility (WRRF) located in the western area of the City. The sewer collection system includes approximately 322 miles of gravity sewers, 4 miles of force mains, and 9 lift stations. The City’s sewer service area includes approximately 29,700 residential, 2,800 commercial/industrial, and 100 agency connections with average dry weather flow of approximately 11 million gallons per day (mgd) and maximum wet weather flow of approximately 45 mgd with wet weather storage.

The City last updated its sewer collection system master plan in 2015. Since this time, nearly all of the capital improvements recommended in the 2015 Master Plan have been completed. The City is planning to complete a new flow monitoring program to collect dry and wet weather flow data, update and recalibrate the City’s InfoWorks ICM hydraulic model to reflect the improvements that have been completed, recalibrate the hydraulic model to new flow data, reassess current and future capacity needs using updated model, recommend short- and long-term capital improvements required to convey current and future wastewater flows, and incorporate a narrative that acknowledges the new capacity-related requirements of the Statewide Waste Discharge requirements that became effective in May 2023 (see Task 4 in Scope of Work). The master plan update does not include an evaluation of rehabilitation and replacement needs to address pipe defects, as the City conducts these assessments apart from the capacity analysis.
