REQUEST FOR PROPOSALS FOR CONSTRUCTION MANAGEMENT AND INSPECTION SERVICES FOR INLAND EMPIRE BRINE LINE REACH IV-B LOWER MAINTENANCE ACCESS STRUCTURES PROJECT

Description: The DIP section of Reach IV-B is approximately 1.6 miles of 36-inch pipeline which crosses several streets in the City of Corona and runs along the Riverside County Flood Control’s Temescal Creek Channel access road. This section of the Brine Line conveys highly saline brine water primarily from five desalters and several industrial dischargers via gravity to Reach IV downstream. The Reach IV-B daily flow is about 5 – 7 million gallons per day (MGD). In 2023, SAWPA hired a consultant to conduct a condition assessment on the DIP section of Reach IV-B. Due to access limitations on Reach IV-B the consultant recommended adding additional MAS on Reach IV-B to provide access for cleaning, inspection and future repairs. In 2025, SAWPA hired a design engineering firm to implement the design of two maintenance access structures on Reach IV-B Lower. Final Plans and Specifications are anticipated in December 2026. It is the intent of SAWPA to obtain the services of a professional firm to perform construction management (CM) services to oversee construction activities and provide inspection of the work to ensure the project is installed according to the plans and specifications prepared by the design engineer.
