About this file
This is a design report appendix for the City of Lompoc's Regional Wastewater Reclamation Plant, prepared by consulting engineers and containing detailed technical specifications and equipment data sheets. The document provides plans, sections, and details for the influent pumping station and fabricated pump system, with multiple elevation views and scale drawings. The file includes pump data sheets for two pumping systems: a Fairbanks Morse pump with a design capacity of 5,210 US gallons per minute at 29 feet of head and a 50 horsepower motor, and a Morris pump with a capacity of 7.5 million gallons per day at 30 feet of head and approximately 48.5 horsepower. The document references structural requirements, including steel plate conformance to ASTM A36 or A490 Grade C standards with 3/8-inch plate thickness, and compliance with AWWA Specification C201 for all fabrication work.
The design report supports the current Headworks and Influent Meter Improvements Project, which builds upon previous master planning efforts including a 2002 master plan and 2005 design report that identified infrastructure upgrade needs at the facility. The specifications outline inlet piece construction requirements, grouting procedures, and internal bracing to prevent damage during foundation work. The pumping station design accommodates the plant's treatment of wastewater serving approximately 9,000 sewer connections with a current Average Dry Weather Flow capacity of 5.0 MGD. This technical documentation establishes the baseline requirements and performance criteria for the engineering consultant selected to develop preliminary and final design documents for the broader headworks improvements, with proposals due June 30, 2025.
