BACKGROUND AND ANALYSIS
In 2014, the City Council determined that decommissioning the 1948-era La Salina Wastewater Treatment Plant (LSWWTP) was more cost-effective than rehabilitating it. The 2022 LSWWTP Long-Term Facility Upgrade Plan reaffirmed that rerouting wastewater flows to the San Luis Rey Water Reclamation Facility (SLRWRF) was the most sustainable and cost-effective long-term alternative.
To transfer flow from the LSWWTP in the coastal area to the SLRWRF and support the City's water reuse goals, four major facilities are required:
* Oceanside Mesa Garrison Lift Station (OMG LS)
* Oceanside Mesa Garrison Force Main (OMG FM)
* Buccaneer Lift Station (separate contract)
* Buccaneer Force Main (separate contract)
The Buccaneer facilities will route sewer flows from the LSWWTP to combine with the new OMG LS flows, which will then convey flow through the OMG FM to the SLRWRF.
