Overview


Summary

OC San requires temporary bypass pumping at its Sunflower Lift Station for Pump#1 during the 2026/2027 wet weather season. The Contractor shall provide a complete temporary bypass pumping system capable of continuously conveying flows ranging from 10MGD to 40MGD under all anticipated wet well and receiving channel wet well levels.



Background

Due to reliability concerns with Sunflower Pump #1 resulting from work performed under project P1-105, additional standby pumping capacity is needed for the upcoming 2026/2027 wet weather season. This project will procure a 40-MGD temporary bypass pumping system to serve as a spare for Sunflower Pump #2 and provide adequate pumping redundancy until the existing pump #1 reliability issue is resolved.
