Reservoir Upgrades
Fire Mountain and Guajome No. 1 Reservoirs

Inspections and structural evaluations of all 12 of Oceanside’s drinking water reservoirs conducted in 2012 determined that the Fire Mountain and Guajome No. 1 reservoirs require repairs to the structures to meet current seismic requirements. Work needed for the 10 remaining reservoir tanks is currently under evaluation.

The retrofits and repairs are needed to minimize earthquake vulnerability and ensure the safety, security and reliability of our water supply stored at the Fire Mountain and Guajome No. 1 reservoirs. Construction work includes excavating the soil around the buried portions of each structure, removing the gunite (exterior concrete), and constructing new connections to tie the footings to the walls and the walls to the roof. Repairs will also be made to reservoir piping and surrounding buildings. Safety and security improvements will be made at each reservoir site as well.

The construction team is required to keep noise within regulations and sound walls will be erected to reduce noise impact. The contractor will also be required to control dust levels and not allow trucks to idle at the project site during working hours.

When all the repairs are completed, both tanks and surrounding buildings will receive aesthetic enhancements including fresh coats of new paint.


Work on the Fire Mountain and Guajome No. 1 reservoirs is expected to begin in October 2014 and take approximately one year to complete.

Myers-Tait Sewer Pipeline Replacement Project

The City of Oceanside is replacing outdated sewer pipelines throughout the city to ensure the pipelines can handle current demand and projected future demands. The existing lines that travel under the streets of Myers and Tait are between 30 to 80 years old. These pipelines will be replaced with newer and larger pipes. The City’s goal is to ensure continued reliable water and sewer service for all customers, and minimize breaks that are often associated with older pipelines. The improvement project will begin the summer of 2013 and take approximately 18 months to complete.

Oceanside Harbor Desalination Testing Project

The City of Oceanside is installing test wells in the Oceanside Harbor to determine the feasibility of using desalinated water as a way to supplement its water supply. Work began in November and will be finished in early 2013. Click on the links below to read a project fact sheet and view a map of the Harbor to see where the work is occurring.  As of this posting, the project has been delayed until this Fall.

Lake Boulevard Sewer Replacement


Sewer pipeline replacement work is being conducted in the roadway on Lake Blvd., College Blvd., Esplanade St. and a very short section of Mira Costa (see map). The work will improve the efficiency of wastewater flow and help to reduce odors in the area.


Work will require at least one road lane to be closed during construction and possible detours around some mall/business entrances to allow for trenching work in the roadways. When work is not underway, non-skid steel plates will be installed. They will be recessed to minimize noise impacts.


Construction Schedule

Construction will begin in late March 2015 and be completed by winter 2015. On Lake Blvd., Esplanade St. and Mira Costa St., work will be conducted during the day to avoid nighttime noise and impacts to residents. Daytime work hours will take place from 8:30 a.m. to 4:00 p.m. On College Blvd., work will take place at night to minimize potential traffic impacts for vehicles accessing State Route 78. Night work will take place on from 9:00 p.m. to 5:00 a.m.
