The RFP is due end of day (5PM) on January 3, 2018. The Consultant’s Fee Proposal shall be submitted in a separate email marked with “Fee Proposal” clearly on the subject line.

Western provides wholesale and retail water services to a population of approximately 894,000 over roughly 527 sq. miles in Riverside County. Western’s potable and recycled water system includes 128 pumps, 621 miles of pipeline ranging from 4 to 60 inches, and 38 water storage reservoirs. Western’s wastewater system includes approximately 8,000 service connections, 24 lift stations and 2 wastewater treatment plants. A Western map is provided in Appendix 1.

The focus of this RFP relates to both the potable and recycled water transmission and distribution systems. Some pipelines are steel with existing corrosion test stations. There are several types of test type stations i.e.: Native potentials, Cathodically Protected and Rectifier Impressed Current.  Western staff took potential readings from these stations, and accumulated test results. This data, along with leak reports, has been used to prioritize pipeline replacement projects and installation of anodes on certain pipelines.

The pipelines are located throughout Western’s service area, generally in the Woodcrest, El Sobrante and Gavilan Hills area of Riverside County and the Orangecrest area of the City of Riverside. Western will supply to the successful Consultant detailed atlas maps, locations of ALL corrosion test stations and rectifiers and access to Western’s as-built drawings.

Western will require the services of an engineering consulting firm (Consultant) to provide 1) professional corrosion protection monitoring services for the existing infrastructure and 2) provide professional corrosion engineering services to support Western’s Corrosion Control Program. The contract will be for the remaining current fiscal year (FY2017-2018) ending June 30, 2018. Western will re-evaluate its approach for the next fiscal year (FY2018-2019).




Western is requesting proposals for professional engineering services for its Corrosion Control Program.
