Lompoc Wastewater Master Plan Volume I – Report Summary

This file is a master planning report prepared for the City of Lompoc, California, documenting infrastructure assessment and planning for the Regional Wastewater Reclamation Plant. The report supports the current Headworks and Influent Meter Improvements Project, which seeks design and engineering services for critical wastewater treatment facility upgrades. The project scope includes replacing the 1974 influent gate and actuator, installing three new bar screens, rehabilitating concrete influent channels, developing a bypass pumping plan, and implementing an odor control system. A mandatory pre-bid job walk is scheduled for May 14, 2025, with proposals due by June 30, 2025, at 3:00 pm. All proposals must remain valid for 90 calendar days after the bid opening date. The City will award the contract to the most responsive and responsible bidder based on comprehensive evaluation of technical capabilities and proposed approach. The contract compensation will be based on approved actual time and materials, not to exceed an agreed-upon "Not-to-Exceed Fee," with progress-based payments contingent on task completion.

The project builds upon previous master planning efforts, including a 2002 master plan by Kennedy/Jenks Consultants and a 2005 design report by Brown and Caldwell. The facility currently serves approximately 9,000 sewer connections with an Average Dry Weather Flow capacity of 5.0 MGD. Previous design reports estimated total project costs for various plant improvements ranging from approximately $300,000 to over $41 million for comprehensive upgrades. Insurance requirements mandate $1,000,000 in Errors and Omissions Professional Insurance, with additional coverage for general liability, automobile liability, and worker's compensation. The contract does not explicitly specify set-aside designations for disadvantaged enterprises. This project represents part of a phased approach to modernizing the facility's infrastructure in Santa Barbara County.
