About this file
The document is a technical engineering file for the Lompoc Regional Wastewater Reclamation Plant (LRWRP), specifically an appendix detailing pump specifications and design plans from March 1974 for the facility's influent pumping station. The file contains detailed technical drawings and performance data for two pump models: a Fairbanks Morse 60 Hz pump with a flow rate of 5210 US gallons per minute and a Morris Pumps model designed for 7.5 million gallons per day, both intended for water treatment applications. The drawings include plan views at various elevation levels, pump base and inlet piece configurations, and comprehensive performance evaluation metrics including head, efficiency, power requirements, and dimensional specifications.
The technical document is part of a broader infrastructure improvement project for the City of Lompoc's wastewater treatment facility, which serves approximately 9,000 sewer connections with a current Average Dry Weather Flow capacity of 5.0 MGD. While the 1974 document provides historical context, it supports the current Headworks and Influent Meter Improvements Project, which aims to upgrade critical wastewater treatment infrastructure. The project involves 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. The procurement seeks a qualified engineering firm to provide comprehensive design and engineering services, with proposals due by June 30, 2025, and an anticipated contract award based on technical capabilities and proposed approach.
